Electric motor launch

FOR SALE: Duffy 21 Classic TRANSFORMED with 2022 technology

This Duffy 21 has the eye-catching aesthetics of a classic launch that’s been professionally repowered with the latest in electric motor propulsion and lithium-ion battery technology. It’s offered at $39,400 and immediately ready to cruise!

The transformation began with the removal of the antiquated, brushed golf cart inboard motor and its noise-producing, belt driven prop shaft. Those components were replaced by the ePropulsion Navy 3.0 EVO Pod motor system—a silent, brushless motor with easy-to-ready digital Bluetooth display of available range and side mount control throttle.

The Navy 3.0 EVO Pod motor system, with CANBUS communication, was paired with ePropulsion’s lithium iron phosphate (LiFePO4) E series batteries. The two E-80 batteries with 8.2 kWh of available energy are no-maintenance upgrade from the Duffy’s original battery bank of 16, 6-volt, flooded lead-acid batteries. A new smart lithium battery charger quickly provides a full charge in half the time as its predecessor.

The Duffy 21 Classic is built for comfort and enjoyment! In addition to this Duffy 21’s repower with new technology, every component of this classic was updated as follows:

  • New AC/DC bow 12V marine refrigerator, which keeps its contents cold on shore power or battery power when cruising.
  • new 4 -speaker, Bluetooth sound system,
  • new USB and 12V charging receptacles,
  • New 12V AGM house battery automatically charged by the new Victron DC to DC converter
  • Quantity 2 – water-sensing bilge pumps
  • New hoses
  • New thru-hull fittings
  • New shore power receptacle
  • New 50’ shore power cord
  • New rub rail New sheer and boot striping
  • All onboard and running lights replaced with new energy saving LED lighting.

Relax into the comfortable surround seating all underneath the cooling shade of the new Duffy factory-made, navy-colored Sunbrella surrey top and its matching helm cover*. Make this Duffy your own with your choice of a complementary vinyl name and port, installed on the transom!

Also included is the complete USCG safety package; life vests, throw cushion, flares, fire extinguisher, horn, anchor, chain and rode, boat lines and fenders. Plus, the boat’s original and reconditioned ensign post and a new ensign flag, along with its burgee post for you to select the burgee pennant of your creative choice.

All combined with a professional hull, deck and stainless detail job which brings this classic boat to its protected and sparkling appearance. This boat is the pure essence of a classic with today’s technology infused.

Duffy 21 Classic Electric Boat Available for Custom Design

People looking for a used electric boat don’t have a lot of choices when it comes to the look and feel. Often they end up settling for white-on-white vinyl interior cushions, a scalloped surrey top, and a motor system that hasn’t been updated for decades.

We have a 2000 Duffy 21 Classic hull available and ready for our professional vessel refit service — and we’re not talking about just adding colorful throw pillows and new name on the transom. With a custom design selected and delivery date set, our clients can put an endpoint on their quest for the perfect electric boat and start making plans to enjoy it with friends and family.

The Duffy 21 Classic Refit Process starts with adding a steerable 4.3 kW electric steerable Piktronik pod-drive motor to replace the Duffy’s antiquated brushed-DC motor and twin power rudders. The steerable pod provides vast improvements for the Duffy’s maneuverability in tight quarters.

Next we work to guide you through selecting the batteries that are best suited for how you plan to use your new electric boat. There’s lots of talk about lithium-ion vs. AGMs vs. Carbon vs. wet-cell “golf cart” batteries. We provide the facts (and dispel some fictions!) about each chemistry  so you can understand how it will fit with your needs.

Now it’s time for the fun part — interior and exterior! We work with yacht interior designers, canvas experts, and vinyl wrap technicians to get the exact look that you want. Sure, you can keep the white fiberglass center-line table with molded cup holders–but why, when you could have a custom wood table with an inlay of your choice? And vinyl is not final, unless you want it be. The interior cushions can be upgraded to stain-resistant, faux leatherette. Integrated nonskid cabin sole (the interior deck area) can be fitted with a woven teak and holly other pattern mat or carpet. Remember, sky’s the limit. If you want the interior of your boat to look like Elvis’s Jungle Room, we can do it.

Your custom Duffy 21 Classic can be stored on a trailer or in the water. We offer aluminum dual-axle trailers that are specifically made to properly support a Duffy. If you plan to leave your boat in the water and don’t have a need for a trailer, delivery service can be arranged.

Refitting used electric boats is our specialty and our passion. To start your custom design of this electric boat call us at 727-517-5330 or [email protected].
