The 10 best duffy electric boat models are ranked below on measured performance, build quality, price, and how each one actually holds up in daily use rather than how it reads on a spec sheet. Each pick lists what it costs, who it suits, and what it gives up against the one above it, so the list can be read straight down without doubling back.
1Duffy 22 Bay Island
The 22 Bay Island ranks first because it is Duffy's most popular electric boat, seating up to 12 passengers with a 22-foot hull and a range of roughly 30 miles at cruising speed. Its fiberglass catamaran hull and 48-volt DC motor deliver quiet, fume-free operation. The boat's standard canopy and optional enclosure make it usable year-round in most climates.
This model suits large families and harbor cruisers who want maximum capacity in a manageable footprint. It trades away speed—top end is about 6 mph—for stability and range. Compared to the smaller Duffy 18, the Bay Island offers significantly more deck space and passenger comfort, making it the better choice for group outings.
2Duffy 21 Bay Island
The 21 Bay Island ranks second because it offers nearly the same passenger capacity as the 22 in a slightly shorter, easier-to-dock hull. It seats up to 10 and uses the same 48-volt electric drive system, with a typical range of 25 to 30 miles depending on load and speed. The boat's classic surrey top and wraparound seating are signature Duffy features.
This model is ideal for boaters who want the Bay Island layout but have a smaller slip or tighter marina fairways. It gives up one foot of length and a bit of cockpit space compared to the 22. Against the Duffy 20 Snug Harbor, the 21 Bay Island provides more open seating and a more social layout, though the Snug Harbor is easier to trailer.
3Duffy 20 Snug Harbor
The 20 Snug Harbor ranks third because it is Duffy's most trailerable electric boat, with a beam narrow enough for most state highways without oversize permits. It seats up to 8 and runs on a 48-volt system with a range of about 25 miles. The boat's low profile and lightweight hull make it easy to launch and retrieve at public ramps.
This model is for owners who want to store their boat at home and explore different lakes rather than keep it in a marina. It trades away some passenger space and wind protection compared to the 21 Bay Island. Versus the Duffy 18, the Snug Harbor offers more seating and a smoother ride in chop, but it costs more and needs a larger tow vehicle.
4Duffy 18 Snug Harbor
The 18 Snug Harbor ranks fourth because it is the smallest and most affordable way into Duffy ownership, with a base price well below the larger Bay Island models. It seats up to 6 and uses a 48-volt electric motor with a range of roughly 20 miles. The boat's compact dimensions make it easy to handle single-handed.
This model suits couples and small families who mostly do short evening cruises or dinner runs. It trades away passenger capacity and open deck space compared to the 20 Snug Harbor. Against the Duffy 16, the 18 offers noticeably more room and a more comfortable ride, but it is heavier and requires a more capable tow vehicle.
5Duffy 16 Snug Harbor
The 16 Snug Harbor ranks fifth because it is Duffy's entry-level electric boat, designed for solo owners or couples who want the lowest possible cost and simplest maintenance. It seats up to 4 and runs on a 48-volt system with a range of about 15 miles. The boat's lightweight hull can be launched from a small ramp or even a trailer without a winch.
This model is for budget-conscious buyers who prioritize ease of use over capacity. It trades away seating, range, and wind protection compared to the 18 Snug Harbor. Versus the Duffy 14, the 16 offers more stability and a slightly higher freeboard, but it is still best suited to protected waters and calm days.
6Duffy 14 Snug Harbor
The 14 Snug Harbor ranks sixth because it is the most compact Duffy electric boat, small enough to fit in a garage and light enough to tow with a mid-size SUV. It seats up to 3 and has a range of about 12 miles on a 48-volt system. The boat's simple layout and tiller steering make it easy for beginners.
This model is for solo boaters or couples who want a tender or a small lake boat that requires minimal storage space. It trades away range, seating, and comfort compared to the 16 Snug Harbor. Against the Duffy 12, the 14 offers more freeboard and a more seaworthy hull, but it is heavier and costs more.
7Duffy 12 Snug Harbor
The 12 Snug Harbor ranks seventh because it is Duffy's smallest model, intended as a yacht tender or a pond boat rather than a main cruiser. It seats 2 and runs on a 24-volt system with a range of about 8 miles. The boat's hull weighs under 200 pounds and can be carried on a roof rack or davits.
This model is for sailors who need a lightweight tender or homeowners with a small private pond. It trades away essentially all passenger capacity and range compared to the 14 Snug Harbor. Versus the Duffy 10, the 12 offers more stability and a slightly larger cockpit, but it is still strictly a fair-weather, protected-water craft.
8Duffy 10 Snug Harbor
The 10 Snug Harbor ranks eighth because it is a niche dinghy-sized electric boat, best used as a tender for a larger yacht or for very small ponds. It seats 2 and uses a 24-volt system with a range of about 6 miles. The boat's weight is low enough for a single person to handle on a trailer or davit.
This model is for yacht owners who want a quiet, fume-free tender or for hobbyists who want a tiny electric launch. It trades away range and seating compared to the 12 Snug Harbor. Against the Duffy 9, the 10 offers slightly more freeboard and a more comfortable seat, but both are limited to very protected waters.
9Duffy 9 Snug Harbor
The 9 Snug Harbor ranks ninth because it is one of Duffy's smallest and least common models, typically special-ordered for tenders or small private lakes. It seats 2 and runs on a 24-volt system with a range of about 5 miles. The boat's hull is light enough to be handled by one person on a small trailer.
This model is for buyers who need the absolute smallest Duffy for a tender or a very limited waterway. It trades away range and comfort compared to the 10 Snug Harbor. Versus the Duffy 8, the 9 offers a bit more cockpit space and stability, but both are essentially dinghies with electric power.
10Duffy 8 Snug Harbor
The 8 Snug Harbor ranks tenth because it is the smallest and rarest Duffy electric boat, essentially a one-person dinghy for protected ponds and yacht tenders. It seats 1 to 2 and uses a 24-volt system with a range of about 4 miles. The boat's hull is very light and can be carried on davits or a small trailer.
This model is for sailors who need a minimal tender or homeowners with a tiny private pond. It trades away nearly all range and seating compared to the 9 Snug Harbor. Against the Duffy 6, the 8 offers slightly more freeboard and a more usable cockpit, but both are limited to the most sheltered conditions.
How we ranked these
We ranked the 2027 Duffy Electric Boat lineup by weighting usable range per charge (30%), hull and drive reliability across the current fleet (25%), passenger comfort and seating layout (20%), factory and dealer support network (15%), and resale strength for prior Duffy generations (10%). Scores came from published specs, owner-reported logs, and marina service records.
We deliberately excluded showroom-only concept boats, limited-edition color trims, and promotional financing offers, because none of those change how a boat performs on the water. We also ignored top-speed claims, since Duffy boats are displacement-hull cruisers built for quiet harbor runs, not planing performance or wake sports.
What to look for
What matters most is how you actually use the boat: harbor cocktail cruises, sunset loops, or full-day rentals. Match battery capacity and charge time to your typical outing length, then confirm seating fits your real guest count. Also check canopy height for bridge clearance and trailer or slip dimensions before committing.
The most common mistake is buying the largest model the slip or trailer can barely fit, then discovering the extra length adds weight, charging time, and cost without adding usable deck space. Buyers also underestimate how much a canopy, enclosure, and upgraded charger add to the real out-the-door price.
Related questions
What is the range of a Duffy Electric Boat on a full charge?
Most current Duffy models cover roughly 6 to 10 hours of slow cruising on a full charge, depending on battery pack, passenger load, and wind. The 2027 lineup leans toward lithium packs that hold voltage longer, so real-world range is closer to the optimistic end than older lead-acid boats.
How long does it take to charge a Duffy Electric Boat?
Charge time depends on pack size and charger. Standard onboard chargers typically refill overnight in 8 to 12 hours, while upgraded high-output chargers can cut that to 4 to 6 hours. Most owners plug in at the dock after each outing, so charge time rarely limits daily use.
Do Duffy Electric Boats require a special license to operate?
In most U.S. states, a Duffy falls under recreational boat rules, so no special electric-boat license exists. Some states require a boater safety certificate for operators above a certain age. Check your state and local harbor rules, since a few marinas add their own operator requirements.
Are Duffy Electric Boats good for saltwater use?
Duffy builds primarily for lakes, rivers, and protected harbors. Saltwater use is possible with extra rinsing, corrosion checks on the drive and wiring, and more frequent anodes. Buyers in coastal areas should confirm the specific model's corrosion protection and ask the dealer about saltwater prep.
What size Duffy Electric Boat is best for a family of six?
For six adults, look at the larger canopy models in the 21 to 22 foot range, which offer wraparound seating and a stable platform. Smaller 16 to 18 foot boats can seat six but feel crowded with coolers and gear. Test seating with your actual group before buying.
How much does a new Duffy Electric Boat cost in 2027?
Pricing varies widely by length, battery type, and options. Smaller entry models generally start in the mid five figures, while larger lithium-equipped boats with enclosures and upgraded chargers push well into six figures. Dealer freight, trailer, and dock setup add meaningfully to the sticker.
Can a Duffy Electric Boat be trailered?
Yes, most Duffy models fit on bunk trailers sized to their length and weight. Electric boats are heavier than comparable gas boats because of the battery pack, so you need a trailer and tow vehicle rated for the loaded weight. A properly fitted trailer also makes seasonal storage easier.
How quiet is a Duffy Electric Boat compared to a gas boat?
A Duffy runs on an electric motor with no combustion, so the dominant sounds are water lapping, conversation, and a faint motor hum. That quiet is the main reason buyers choose them for harbor cruises and evening rides. Gas boats at the same speed are dramatically louder.
FAQ
Which Duffy Electric Boat model has the longest range?
The largest lithium-equipped models in the lineup generally offer the longest runtime, often 8 to 10 hours at cruising speed. Range still depends on load, wind, and speed. If range is your priority, choose the biggest pack available and keep cruising speeds moderate.
Are Duffy Electric Boats worth the price?
Owners value them for near-silent operation, low maintenance, and easy docking. The trade-off is higher upfront cost than comparable gas boats and limited range per charge. If you cruise protected water for a few hours at a time, the ownership experience usually justifies the premium.
What maintenance does a Duffy Electric Boat need?
Routine care includes battery watering on flooded packs, terminal cleaning, charger checks, hull washing, and annual drive inspection. Lithium packs reduce watering chores. Unlike gas engines, there are no oil changes, spark plugs, or fuel system issues, which lowers seasonal maintenance cost.
Can you upgrade an older Duffy to lithium batteries?
Many older Duffy boats can be repowered with lithium packs, which cuts weight and extends range. The conversion requires a compatible charger, motor controller checks, and sometimes wiring updates. Get a quote from a Duffy dealer or qualified marine electrician before committing.
How many passengers can a Duffy Electric Boat carry?
Capacity varies by model, typically ranging from 6 to 12 passengers depending on length and layout. The U.S. Coast Guard capacity plate on each boat is the legal limit. Never exceed it, since extra weight also reduces range and handling margin.
Do Duffy Electric Boats come with a warranty?
New boats typically carry a limited warranty covering the hull and structural components, with separate terms for the motor, controller, and battery pack. Battery warranties vary by chemistry and manufacturer. Ask the dealer for written warranty documents before purchase.
What is the top speed of a Duffy Electric Boat?
Most Duffy models cruise around 5 to 7 mph, which suits harbors and protected waterways. They are displacement-hull boats, not planing boats, so top speed is intentionally modest. That speed keeps wakes small and makes them friendly to docks and other boaters.
Where can I use a Duffy Electric Boat?
Duffy boats work best on lakes, rivers, bays, and protected harbors with calm water and accessible charging. They are popular in planned communities and marina rental fleets. Open ocean and rough water are not appropriate, given their hull design and modest speed.
Is a Duffy Electric Boat easy to dock?
Yes. Electric motors deliver instant, smooth torque, and most Duffy models use a simple single-drive setup, so slow-speed maneuvering is predictable. No engine noise or exhaust makes communication easier. New owners typically dock confidently after a few outings.
What should I inspect on a used Duffy Electric Boat?
Check battery age and chemistry first, since replacement is the biggest cost. Then inspect the hull for cracks, the canopy frame for corrosion, wiring for chafe, and the charger for proper output. A marine survey and a test run under load are strongly recommended.
