The Duffy Back Bay 16 is one of the smaller Duffy models we’ve ever built.  She’s perfect if your lake or waterway has a size restriction or a maximum length for your boat.  This boat includes all the same technology as our other models, including our Duffy Power Rudder.  Don’t let her shorter length fool you – the Back Bay has an amazing amount of interior space to fit plenty of friends and family onboard comfortably for a great cruise to remember.

The new Duffy Back Bay 16 features some exciting new improvements! One of the major differences – the newly redesigned hull, which has been widened to really open up the interior space of the boat and give individuals the freedom to move around freely inside the boat.

The Back Bay 16 comes in at a full eight inches wider than our previous 16′ model. Combine the extra width of the boat, along with the unfixed, movable tables and the side-steering helm (thanks to our patented Duffy Power Rudder), and you’ve got a completely different boat with an open interior to move about.

The Back Bay 16 has become a very popular model, thanks to the redesigned shape of the boat and her ability to fit into the smallest of slips. At 16 feet she meets the length restrictions on all of the local lakes and the beautiful spacious interior offers solid wood forward and aft tables, along with both forward and portside cherry wood storage cabinets.

The new three-step entry on both sides of the boat makes it extremely easy for anyone to get in and out of the boat!

There’s also a built-in ice chest under the aft side seat! The fully insulated ice chest drains straight to the bilge pump. With the automatic float switch sensor, there is no need to take the ice out yourself!

One of the biggest changes to come to the 16 is the location of her batteries. Rather than being under the seats like on our previous models, the batteries are now located in the keel of the boat. This provides great stability and unparalleled tracking for a boat of this size. You also have lots of space under the seats for storage!

Our new Duff Eze III polycarbonate window system is fully UV proof and keeps you warm and toasty on the coldest of days. The enclosure will also keep any rain or dirt outside the boat, without the need for a full boat cover! Just unplug, untie, and unwind!

The 2021 Back Bay model includes some other exciting changes. The new Lonseal flooring gives the look of a beautiful teak floor, but without the hassle! Easy to clean and soft on your feet, it will last forever. The “Smart Plug” power connector is included on all our 2021 boats and provides faster and more efficient charging. Navigation and interior lighting have been replaced with new efficient LED lights, which will last for years!

Like all Duffy models, the Back Bay 16 comes with the new Fusion stereo. Play music, or take calls wirelessly with Bluetooth, tune in the AM/FM radio, or plug in for a quick charge while you play your favorite songs through the USB port!

We here at Duffy are very proud of this model, and we look forward to building you one of America’s first and finest electric boats as we have since 1970!

Like all of our Duffy Electric Boats, the Back Bay 16 is made in America.
