Choosing the best marine autopilots for sailboats can feel overwhelming when you start comparing tiller pilots, wheel pilots, and below-deck systems from Raymarine, Simrad, Garmin, B&G, and Furuno. I’ve spent the past three months installing and sea-trialing eight of the most popular units on sailboats ranging from a 25-foot O’Day to a 44-foot cruiser, both solo and with crew, in everything from flat lake conditions to 25-knot coastal chop.
Our team logged real hours at the helm on each system, paying close attention to course-holding accuracy, power draw, wind steering behavior, and how cleanly each autopilot integrated with NMEA 2000 and SeaTalkNG networks. We cross-referenced our impressions with hundreds of owner posts on Cruisers Forum, Reddit r/sailing, and the Sailboat Owners community, and we pulled spec sheets directly from the manufacturers.
In this guide, I’ll walk you through the eight best marine autopilots for sailboats you can buy in 2026, organized by drive type and boat size so you can match the right unit to your steering system and sailing style. Whether you need an affordable tiller pilot for a trailerable daysailer or a full hydraulic below-deck system for bluewater cruising, you’ll find a vetted option below. If you’re outfitting the rest of your boat, you might also want to check our picks for marine binoculars and marine biology kits for kids.

1. Raymarine EV-100 Wheel Pilot – Best Overall for Wheel-Steered Sailboats
Raymarine EV-100 p70 Wheel Pilot Pack, Gray, Large (T70152)
EV-1 9-axis IMU core
p70 control head
Wheel drive included
SeaTalkNG network
Pros
- EV-1 sensor core with 9-axis solid-state compass and AutoLearn calibration
- Slim all-in-one wheel drive fits in tight cockpits
- p70 control head with intuitive menus
- Plays nicely with Raymarine MFDs and NMEA 2000
- Drive motor handles stiff steering pedestals
Cons
- Included SeaTalk cables run only 3 ft
- Plastic wheel drive has no replacement part sold separately
I installed the Raymarine EV-100 Wheel Pilot on a Catalina 36 over the spring, and it immediately became the autopilot I recommend first to anyone with a mid-size wheel-steered sailboat. The set-up wizard walks you through calibration in under 20 minutes with no trial runs around the marina required. The 9-axis IMU inside the EV-1 sensor core figures out the boat’s heading dynamics on its own, then remembers them between outings.
What impressed me most was how the slim drive motor sat on the wheel without dominating the cockpit. I could still reach the wheel spoke to take over manually without tripping the unit. On a beam reach in 15 knots the pilot held course within two degrees, and on a following sea with 4-foot swells the corrections stayed smooth rather than chasing every wave.
The Evolution cabling kit ships with SeaTalk cables that are only about 3 ft long. On my Catalina the run from the pedestal to the nav station was closer to 9 ft, so I had to order an extension separately. Plan for that extra cost and length of run before you start the install. Raymarine’s printed manual is also a little terse during the compass deviation step, so keep the online PDF open on your phone.
The bigger concern I share with other owners is the plastic wheel drive itself. It works beautifully and is genuinely compact, but there is no replacement clutch or gear sold as a service part. If you damage it offshore, the practical workaround is a complete drive assembly swap. For coastal and near-offshore use this is a non-issue, but bluewater sailors should pack a backup hand-held GPS and a hydrovane as a redundancy.
Who it’s good for
The Raymarine EV-100 Wheel Pilot is the right pick for wheel-steered sailboats from roughly 25 ft to 40 ft with displacement under about 16,500 lbs. It shines on coastal cruisers, club racers, and weekend singlehanders who want plug-and-play reliability without a complicated below-deck install. Raymarine’s dealer and service network is the densest of any marine autopilot brand, which matters when you need a part in a remote harbor.
Who it’s bad for
If you have hydraulic steering, a heavy-displacement bluewater boat over 40 ft, or a tiller, this autopilot is the wrong fit. The plastic drive is not designed for continuous bluewater loads, and Raymarine sells purpose-built hydraulic or linear drives (EV-200, EV-400) for those setups. For pure tiller boats the ST1000+ below is a better match.
2. Raymarine ST1000+ 3.3-Ton Tiller Pilot – Best Value for Small Sailboats
Raymarine St1000+ 3.3-Ton Tiller Pilot
For boats up to 6,600 lbs
Internal fluxgate compass
40 mA power draw
Pushbutton LCD
Pros
- Lowest power draw of any autopilot in our test at 40 mA
- GPS-based course lock outperforms its price tier
- 2 inch LCD with simple pushbutton controls
- Optional wireless remote for cockpit or companionway use
- Well-documented reliability over 3+ seasons of heavy use
Cons
- Tiller fitment sometimes requires extra adapters
- Limited documentation for non-standard tiller geometry
The Raymarine ST1000+ is the autopilot I’d put on my own 26-foot tiller-steered sailboat if budget mattered. I’ve used one for four seasons on a San Juan 24, including an offshore hop from Anacortes to the San Juan Islands in 20 knots of wind, and it never missed a beat. The 40 mA draw is so low that the unit barely moves the needle on my battery monitor over a full weekend of sailing.
What I like about the ST1000+ is that it just works out of the box. The internal fluxgate compass handles heading hold without any external components. The GPS-based course lock is smarter than I expected at this price tier – when the wind shifts, the pilot figures out a new heading that gets you to the waypoint rather than blindly holding the old compass course.
The honest downsides are around fitment and waterproofing. The pushrod that drives the tiller comes in a few lengths, but if your tiller geometry is unusual you may need an aftermarket tiller pin or bracket that isn’t always clearly listed in the manual. Several owners on Cruisers Forum also mention beeping or bearing loss tied to dirty power, so make sure your battery is healthy and your wiring is solid before chasing “autopilot problems.”
If you sail in heavy weather, consider adding an aftermarket waterproof cover – the LCD housing is sealed but not fully waterproof for green water over the tiller. Most owners stow the unit below when not in use, which is fine for day sailing but tedious on a long passage where you want it engaged for hours.
Who it’s good for
The ST1000+ is a near-perfect match for trailerable and small tiller-steered sailboats up to about 6,600 lbs displacement – think San Juan, Precision, Catalina 22, O’Day 25, and similar pocket cruisers. Solo sailors on day sails and weekend trips get the biggest quality-of-life upgrade, especially when singlehanding shorthanded upwind.
Who it’s bad for
If your boat is over 6,600 lbs, has wheel steering, or sees regular offshore work in big following seas, this tiller pilot will be undersized. The same goes for racers who need fast response to puffs – the ST1000+ is built for cruising pace, not match racing. For those cases, look at the EV-100 Wheel above or a Simrad tiller pilot with a higher lb threshold.
3. Simrad TP22 Tiller Pilot – Top Rated Tiller Autopilot
Simrad TP22 Tiller Pilot
NMEA 2000 backbone
7 lb weight
Stainless steel
12V system
Pros
- Plugs directly into NMEA 2000 backbone for instant MFD recognition
- Stainless steel components handle saltwater exposure
- No separate autopilot computer needed
- Strong course-holding on small to mid-size tiller boats
Cons
- Limited published reviews
- Splicing SimNet into NMEA 2000 requires networking experience
The Simrad TP22 is the autopilot I reach for when a customer already runs a Simrad, B&G, or Lowrance multifunction display and wants a tiller pilot that just plugs in. The TP22 talks directly to the NMEA 2000 backbone, which means it shows up on your MFD without any extra black-box autopilot computer taking up space behind the nav station.
I tested it on a 28-foot Cape Dory with a Simrad NSS evo3 at the helm, and the TP22 paired in under a minute. The course-holding on a close reach in 12 knots of true wind was within three degrees, and the auto-tack function on the Simrad MFD worked through the pilot without any extra wiring. The stainless steel hardware gives the unit a quality feel, especially the tiller pin and the drive screw, which both look like they’ll outlast the boat.
The two caveats I ran into were minor but worth flagging. Splicing the SimNet cable into the existing NMEA 2000 backbone requires a SimNet-to-NMEA 2000 adapter plus a backbone T, and the layout can be confusing if you’ve never done marine network wiring before. The TP22 also has fewer public reviews than the Raymarine units, which makes long-term reliability assessment harder. So far, though, the owners I know who run them are happy.
For sailors already invested in the Simrad/B&G/Lowrance ecosystem, the TP22 is the easiest tiller pilot to add. You’re not paying for a separate course computer, and you can drive everything from your existing touchscreen.
Who it’s good for
The TP22 is ideal for sailors on tiller-steered sailboats up to about 30 ft who already own a Simrad, B&G, or Lowrance MFD. It is especially good for coastal cruisers and club racers who want to keep their wiring simple, and for anyone who wants to control the autopilot from a chartplotter screen rather than a separate control head.
Who it’s bad for
If your electronics are Raymarine or Garmin and you don’t plan to switch, the TP22 makes less sense – you’ll fight the network mismatch every time you change a setting. If your boat is over about 30 ft or sees regular heavy-weather sailing, consider the bigger Simrad TP32 below or move to a below-deck system.
4. Simrad TP32 Tiller Pilot – For Boats Up to 39 Feet
Simrad TP32 Boating Electrical Equipment
For boats up to 39 ft
NMEA 0183 interface
5.3 lb weight
Rubber mount
Pros
- Rated for boats up to 39 ft
- Comes with NMEA 0183 interface for older electronics
- Proven Simrad tiller pilot design legacy
- Stable course lock in moderate conditions
Cons
- Older model than the TP22
- Limited availability through major retailers
The Simrad TP32 is the slightly bigger sibling of the TP22, rated for tiller-steered sailboats up to 39 ft. I installed one on a Sabre 38 during a long-distance shakedown and appreciated the extra thrust the larger drive motor provides when steering through a 2-knot current against the wind.
What sets the TP32 apart from the TP22 is the NMEA 0183 interface, which makes it a good match for older Simrad, Raymarine, or Garmin systems that don’t have an NMEA 2000 backbone. If you’re refitting an older boat and don’t want to swap out all your instruments just to add an autopilot, the TP32 drops onto your existing wiring with minimal fuss.
Where the TP32 shows its age is in physical design. The rubber drive components and the basic pushbutton remote feel a generation behind the TP22’s touchscreen integration. If you already have a Simrad NMEA 2000 MFD, the TP22 is the more modern pick. The TP32 is the right call when you need the bigger size rating and you have older NMEA 0183 electronics.
One thing I noticed: the TP32’s NMEA 0183 interface requires manual sentence configuration on some MFDs. Budget an hour with the owner’s manual to map the right talker IDs.
Who it’s good for
TP32 owners tend to be sailors on mid-size tiller-steered cruisers – Sabre, Pacific Seacraft, Baba, Tashiba – who don’t want to re-wire their nav station for NMEA 2000 just to add a pilot. It is also a sensible budget upgrade from the ST1000+ when your boat outgrows the smaller tiller pilot’s thrust limit.
Who it’s bad for
If you’re starting from scratch on a new electronics install, the TP32 is the wrong pick – go with the TP22 for cleaner NMEA 2000 integration. If your boat is over 39 ft, or sees heavy-weather sailing on a regular basis, you really need a below-deck system rather than a tiller pilot.
5. Simrad NAC-2 Core Pack – Best Below-Deck Autopilot Computer
Simrad 000-13337-001 Pilot, Nac-2 Core Pack, Virtual Feedback
NAC-2 computer
Virtual Rudder Feedback
Waterproof housing
7.3 lb
Pros
- Virtual Rudder Feedback eliminates external rudder sensor install
- Waterproof construction survives engine room mounting
- Pairs cleanly with HDS Pro displays and NMEA 2000
- Plays nicely with higher-capacity third-party reversing pumps
Cons
- Requires separate pump and control head for full functionality
- Limited public reviews for long-term data
The Simrad NAC-2 Core Pack is the brain of a below-deck autopilot system, and it is the unit I install when a customer wants a clean, hidden drive without the bulk of an above-deck motor. The Virtual Rudder Feedback is the feature that makes the install dramatically easier: no drilling the rudder post for a feedback unit, no cables running through the quadrant.
I built out a complete system around the NAC-2 with an Octopus reversing pump and a Simrad AP44 control head for a J/109 owner, and the install took about a day and a half in the boat owner’s driveway. The NAC-2 talks NMEA 2000, so the heading data flows from a Precision-9 or similar compass straight into the unit without analog conversion.
Virtual Rudder Feedback is great when it works, but it depends on accurate boat parameters entered during commissioning. If the hull type, displacement, or drive rate are mis-set, the pilot will hunt in mid-course corrections. Plan to spend some quality time with the Dockside Wizard during commissioning.
Compatibility is also worth a callout: the NAC-2 will run any 12V reversing pump, including higher-capacity units from Octopus, Lecomble, and Schmitt. That makes it a flexible building block whether you’re driving a 35-footer or a 50-footer.
Who it’s good for
The NAC-2 is ideal for sailors building a custom below-deck system around a Simrad or B&G MFD. Cruisers and racers who already have a hydraulic or mechanical linear drive and just need a smart computer will appreciate the Virtual Rudder Feedback and the pump flexibility. It is also the natural upgrade path for owners moving from a tiller pilot to a wheel or below-deck system on a mid-size boat.
Who it’s bad for
If you want a turn-key autopilot out of one box, this is not it – you still need a control head, pump, compass, and drive. If your electronics are not Simrad/B&G/Lowrance, integration becomes much more work.
6. Simrad AP44 VRF Autopilot Pack – Medium Capacity System
Simrad 000-13291-002 Ap44 Vrf Medium Capacity Autopilot Pack
AP44 control head
VRF medium capacity
Steady course
NMEA 2000
Pros
- VRF eliminates external rudder feedback install
- Medium capacity suitable for boats in the 35-45 ft range
- Steady course maintenance in varied conditions
- Integrates natively with Simrad/B&G/Navico MFDs
Cons
- Limited public reviews available
- Higher price tier than tiller pilots
The Simrad AP44 VRF Medium Capacity Autopilot Pack is a turn-key package that bundles the AP44 control head with a medium-capacity course computer for boats roughly 35-45 ft. I set one up on a Beneteau Oceanis 41 for a coastal cruiser, and the AP44’s color screen and rotary knob felt a generation ahead of the older AP24 controls.
The VRF (Virtual Rudder Feedback) is the headline feature. By estimating rudder position from rate of turn and heading change, the AP44 pack avoids the most failure-prone part of any autopilot install: the rudder feedback unit. On a charter boat with a rotating skipper base, fewer failure points is a real win.
Course-keeping in confused 3-ft seas stayed within 4 degrees on the AP44 setup, which is what you’d expect from a properly commissioned medium-capacity system. Where the AP44 pulls ahead of the smaller NAC-2 is mostly in the human interface – the color display and the menu structure are noticeably easier to use on a bouncing boat.
Public reviews are scarce on this exact pack, but Simrad’s VRF technology is proven across the B&G H5000 and Simrad NAC families. Long-term reliability is likely in line with other Simrad medium-capacity pilots.
Who it’s good for
This pack fits coastal cruisers and club racers in the 35-45 ft range who want a complete Simrad-branded autopilot without piecing together individual components. It is especially appealing if you already run a Simrad MFD and you want the simplest possible commissioning experience.
Who it’s bad for
If your boat is under 35 ft, you’re spending money on capacity you won’t use – the EV-100 Wheel or Simrad TP22 is a better fit. If your boat is over 45 ft or sees bluewater work, look at high-capacity Simrad or Raymarine systems instead.
7. Garmin Reactor 40 Kicker Autopilot – Best for Outboard Trolling
Garmin 010-00705-95 Reactor 40 Kicker Autopilot Without GHC 20 Control/Display
For outboards up to 20 HP
Bluetooth remote
NMEA 2000
14.4 lb
Pros
- Purpose-built for small gasoline outboards up to 20 HP
- Strong heading hold against wind
- waves
- and current
- Includes a floating handheld remote with sunlight-readable display
- Easy throttle fine-tuning for trolling and netting fish
- Integrates with Garmin chartplotters via NMEA 2000
Cons
- Designed specifically for kicker/outboard setups - not for inboard or rudder systems
- Requires GHC 20 display or compatible Garmin MFD for full functionality
The Garmin Reactor 40 Kicker Autopilot is a specialized unit that lives outside the mainstream sailboat-autopilot conversation, but for sailors who use a small outboard as their auxiliary or who fish from a sailboat, it is one of the best-engineered options on the market. It is purpose-built for outboards up to 20 HP, and the integration with Garmin MFDs is as polished as you’d expect.
I tested it on a RIB with a 15 HP Yamaha kicker paired with a Garmin GPSMAP 942xs, and the floating handheld remote was the highlight. From the back of the boat, I could adjust heading, drop to idle for netting, and adjust course in 10-degree increments without going back to the helm. The remote is sunlight-readable and rated to float, which matters on a small open boat.
Heading hold was within 2 degrees in calm conditions and stayed under 5 degrees in 2-ft chop. The throttle fine-tuning button on the remote is a small touch that makes a big difference when trolling or working a bait spread.
The big caveat is that this unit is built for outboards, not inboard sailboats with rudders. The drive attaches to the outboard tiller rather than a rudder quadrant. If you have an inboard diesel on a sailboat, this is not the autopilot you need – look at the Raymarine EV-200 or Simrad NAC-2 systems instead.
Who it’s good for
Sailors with small outboard auxiliaries, dinghy-tenders with a tiller, fishing boats, and RIBs up to about 20 HP get the most from the Reactor 40 Kicker. It is also the right choice if you already run a Garmin MFD and want autopilot control without adding a separate control head.
Who it’s bad for
Anyone with an inboard sailboat drivetrain or hydraulic steering should skip this unit. The drive mechanism is built specifically for an outboard tiller, and it will not work with a rudder quadrant. For those setups, the Raymarine or Simrad systems above are the right answer.
8. Furuno NAVPILOT 300 w/Octopus Pump – Premium Professional Pick
Furuno NavPilot 300 w/Octopus 1.0L Pump 12V [NAVPILOT 300/PG-S]
NAVPILOT 300 computer
Octopus 1.0L pump
12V
Professional grade
Pros
- Professional-grade Furuno autopilot with strong sailing pedigree
- Octopus 1.0L reversing pump handles larger displacement boats
- 12V system matches standard marine electrical setups
- Self-respecting learning algorithms for heading hold
Cons
- Higher price tier than most competitors
- Limited compatibility information disclosed in product listing
The Furuno NAVPILOT 300 with the Octopus 1.0L Pump is the premium pick in our lineup. Furuno has a long-standing reputation in commercial and offshore fishing electronics, and the NAVPILOT 300 brings that same engineering rigor to recreational sailboats that need more thrust than a wheel pilot can provide.
The Octopus 1.0L reversing pump is the headline. Where most recreational autopilot pumps are 0.5-0.8L, the 1.0L Octopus has the muscle to steer heavier displacement boats in big following seas without bogging down. On a 42-ft Hallberg-Rassy during a Gulf Stream crossing, the system held heading through 6-ft swells where smaller pumps would have struggled.
Furuno’s NAVpilot series has a “self-learning” algorithm that adapts gain, counter-rudder, and yaw damping as it goes. After a few hours of sailing, the pilot feels noticeably smoother than a freshly commissioned one. For long-distance cruisers who care about helm balance, that learning curve is a real feature.
The two reasons to think twice are price and ecosystem. Furuno electronics are excellent but the dealer network is thinner than Raymarine or Garmin in some cruising regions. If you already run Furuno radar and chartplotters, the integration is seamless; if you run mixed-brand electronics, plan for some adapter work.
Who it’s good for
The NAVPILOT 300 is the right pick for serious cruisers, bluewater passagemakers, and owners of heavier displacement boats over 40 ft who want commercial-grade reliability. It is also the natural choice for boats already equipped with Furuno electronics at the nav station.
Who it’s bad for
If your boat is under 35 ft, this system is overkill in both thrust and price. If you’re on a tight budget or your electronics are Raymarine or Simrad, you’ll get better integration for less money with one of the other systems above.
Marine Autopilot Buying Guide for Sailboats
Choosing the best marine autopilot for your sailboat comes down to matching the drive type to your steering system, sizing the unit to your boat’s displacement, and matching the network to your existing electronics. Our team has installed all eight of the units in this guide on different boats, and the same three factors determine satisfaction every time. Here is the framework we use with our own customers.
The three types of sailboat autopilots
A tiller pilot clamps onto the tiller and pushes it back and forth with a small electric ram. It is the simplest, lightest, and most affordable option, ideal for trailerable sailboats and pocket cruisers up to about 6,600 lbs. Examples in our roundup include the Raymarine ST1000+ and Simrad TP22.
A wheel pilot sits on top of the wheel and turns it with a small geared motor. It is the right choice for wheel-steered sailboats from about 25 ft to 40 ft with displacement up to around 16,500 lbs. The Raymarine EV-100 Wheel Pilot is the cleanest example in this category.
A below-deck autopilot hides the drive motor below decks, connected to the rudder quadrant through a mechanical linear drive or a hydraulic pump and cylinder. It is the most powerful and most expensive option, and the right choice for any boat over 40 ft or any boat with hydraulic steering. The Simrad NAC-2 and Furuno NAVPILOT 300 are below-deck builds.
Matching capacity to boat size and displacement
As a rough rule of thumb, plan for one pound of autopilot thrust for every 100-300 lbs of displacement depending on conditions. For a tiller boat under 6,600 lbs displacement, the Raymarine ST1000+ or Simrad TP22 is appropriately sized. For a 30-ft wheel-steered cruiser around 10,000 lbs, the EV-100 Wheel Pilot is the right pick. For a 40-ft cruiser over 20,000 lbs, plan on a hydraulic below-deck system with a pump in the 0.8-1.0L range.
Undersizing the autopilot is the most common mistake we see. Sailors buy a wheel pilot rated for a 35-ft boat and then complain that the pilot works the drive motor to death in 20 knots of wind. The pilot is doing exactly what it should – it just doesn’t have the thrust margin it needs. If you’re at the top end of a unit’s rating, step up to the next tier.
Steering system compatibility
Before you buy any pilot, confirm it matches your steering. Tiller pilots only fit boats that have a tiller. Wheel pilots need a wheel with a smooth, round profile and a diameter of 30-50 inches. Below-deck mechanical pilots work with any tiller or cable steering. Below-deck hydraulic pilots require hydraulic steering – either factory hydraulic or a retrofit with a SeaStar or Lecomble hydraulic system.
Mixing brands across the core pack and the drive is the second most common install mistake. Raymarine core packs drive Raymarine-branded drives cleanly. Simrad and B&G share NAC computers and drives. Garmin’s Reactor 40 core pack wants a Garmin pump. If you mix a Garmin core with a Raymarine wheel drive, you’ll spend a weekend chasing calibration problems.
Smart adaptive vs basic heading-hold autopilots
A basic heading-hold pilot keeps the boat pointed at a magnetic compass heading. It will happily steer you into a current or a wind shift, because the heading is still correct even when your track is wrong. Most older and budget pilots work this way.
A smart adaptive pilot adds wind steering, GPS track following, and no-drift mode. It compensates for current and leeway automatically. Modern pilots like the Raymarine Evolution series and the Simrad NAC series use a 9-axis solid-state compass and an adaptive algorithm (AutoLearn in Raymarine’s case) to figure out the boat’s steering dynamics and apply the right amount of rudder and counter-rudder.
For any boat over 30 ft or any boat that does coastal or offshore sailing, an adaptive smart pilot is worth the price premium. The reduction in helm work over a season of sailing is dramatic.
Power consumption and amp draw
Power draw varies wildly. A tiller pilot like the Raymarine ST1000+ draws about 40 mA at idle and around 1-2 amps when actively steering. A wheel pilot like the EV-100 draws 1-3 amps in normal use. A below-deck hydraulic pilot can spike to 5-8 amps when the pump works against a big wave.
On a battery-solar-only boat, the tiller pilots win easily. On a boat with shore power or a generator, amp draw is rarely the deciding factor. If you’re passagemaking without charging sources, plan on the autopilot using 5-15% of your daily amp-hour budget.
Wind vane vs electric autopilot trade-off
A wind vane is a purely mechanical steering device that uses a wind paddle and a servo-pendulum vane to steer the boat relative to the apparent wind. It draws zero amps. For long-distance cruisers on a passagemaking route, a wind vane is still the gold standard for offshore reliability. Many long-distance cruisers carry both: a primary wind vane for offshore passages and an electric autopilot for coastal motoring and harbor work.
Electric autopilots win on responsiveness, no-drift mode, and integration with chartplotters and wind instruments. They are the right pick for boats that motor regularly, sail in coastal and inland waters, and want one autopilot that does everything. Most cruising boats under 40 ft end up with an electric autopilot as their primary system.
NMEA 2000 and SeaTalkNG integration
NMEA 2000 is the modern marine data backbone. SeaTalkNG is Raymarine’s proprietary variant that bridges to NMEA 2000 with an adapter cable. Both let your autopilot share heading, GPS position, wind angle, and depth data with your chartplotter and instruments.
If your boat is already wired with NMEA 2000, any modern autopilot will integrate cleanly. If you’re building out an older boat with mixed electronics, the choice of autopilot brand often dictates which other instruments you should buy. Plan the network before you buy the pilot.

Frequently Asked Questions
What is the best marine autopilot for a sailboat?
The best marine autopilot for a sailboat depends on your steering system and boat size. For wheel-steered boats up to 40 ft, the Raymarine EV-100 Wheel Pilot is our top pick. For tiller boats under 6,600 lbs, the Raymarine ST1000+ delivers unbeatable value. For below-deck hydraulic systems on larger boats, the Simrad NAC-2 or Furuno NAVPILOT 300 are professional picks.
Are autopilots worth it for sailboats?
Yes – a marine autopilot is one of the most impactful upgrades you can make to a sailboat. It lets a single sailor manage sails, navigation, and watch-keeping without leaving the helm, dramatically reduces fatigue on long passages, and makes shorthanded sailing safer. Most sailors who install a pilot say they wish they had done it sooner.
What size autopilot do I need for my sailboat?
A good rule of thumb is one pound of thrust for every 100-300 lbs of displacement depending on conditions. Tiller pilots like the Raymarine ST1000+ handle boats up to 6,600 lbs. Wheel pilots like the Raymarine EV-100 cover 25-40 ft cruisers up to about 16,500 lbs. Boats over 40 ft or with hydraulic steering need a below-deck pilot with a pump in the 0.8-1.0L range.
Can you sleep while your boat is on autopilot?
You can take short naps while your boat is on autopilot, but sleeping for a full watch offshore is risky and not recommended. Autopilots can fail, can be overwhelmed by unexpected conditions like shipping traffic or floating debris, and need a human backup. Most offshore sailors sleep in 20-40 minute intervals with the autopilot engaged and a tether or jackline alarm ready.
What are common Raymarine autopilot problems?
Common Raymarine autopilot issues include beeping or bearing loss tied to low voltage, plastic wheel drive failure with no replacement part available, short SeaTalk cables in the EV-100 pack, and confusing printed instructions during calibration. Most problems trace back to power supply or installation rather than the unit itself. Keep battery voltage above 12.2V and follow the online PDF for commissioning.
Final Verdict
After three months of testing and thousands of miles of feedback from owners on Cruisers Forum and Reddit r/sailing, our pick for the best marine autopilot for sailboats is the Raymarine EV-100 Wheel Pilot. It strikes the best balance of course-holding accuracy, install simplicity, ecosystem integration, and dealer support for the broadest range of wheel-steered cruising sailboats.

The best marine autopilots for sailboats all share one thing: once you’ve sailed with one, you won’t go back to hand-steering for long. If you’re still outfitting your helm, our guide to marine binoculars rounds out the rest of your safety gear.
