Expensive Modification

The Wood Duck Double has worked out great for my planned uses (duck hunting, fishing, and paddling Lake Superior.) It’s quite a comfortable fishing kayak. My wife and I had planned to buy a Lund 1650 Angler SS v-hull boat as we’re getting more and more into fishing. However, this winter we decided to focus on kayak fishing instead since we can take two kayaks with us everywhere we go with our travel trailer and only need one vehicle.

We purchased a Torqeedo Ultralight 1103 AC electric motor for each of us. This motor puts out 3 hp and includes a 31 amp-hour lithium battery that should produce a range of 40 miles at 3 mph. We bought a Wilderness Systems ATAK 120 fishing kayak for Mary and I’m installing my Torqeedo on the Wood Duck.

Minnesota DNR is considering a change to allow electric trolling motors in their wildlife management areas. This motor would be perfect for getting out to my favorite, distant honey holes for duck hunting. We’ll also modify our triple kayak so we can get a “boost” on our Lake Superior kayak expeditions in the Apostle Islands.

Beef Up the Stern

This kayak is not designed to run a motor. However, I’m not letting that stop me. The motor assembly weighs 20 pounds and I opted to reinforce the stern and go for it!

The wedges lay on the top of the deck and level it so that the motor mount is running closer to level. The 1/4” plywood is custom fit to beef up the underside of the deck at the stern.

I sanded the paint off in this area so the epoxy would get a good bite on the stern deck.

The motor mount is installed and serves as a clamp as the epoxy cures. I’ll seal the new parts with epoxy once this assembly cures.


Raising the seat.

Yeah, this is stretching it a bit for this boat, but I think it should work well. My main concern is how much the stern squats at 3-5 mph. You can get into some “skinny” water with a boat like this!
