Ducktrap Launch Plans


Product Description

Be sure to read all the way to the end...or simply click this link to see time lapse video of a launch being set up in Brazil by Oliver Ilg.

We designed the Ducktrap Launch in 2015 and built over the Winter of 2015-2016. She's a 17' center console V-bottom with lapstrake topsides, a raking curved transom, and one of the easiest riding boats around. (The same offsets can be used to build a longer version.) One design prerequisite was that she be be economical to run, and she is that.  Her 4-stroke 25hp Yamaha running at 5500rpm only consumes 1.69 gal/hr (according to Yamaha).

Here's a portion of her construction plan...


Walter Simmons, who designed and built the first boat, said: With these plans you likely won’t need her lines and offsets at all, though they will be included for obvious reasons. The reason for that is that one page will be her full size keel sections, another the lofted body plan, another the expanded transom, and another her stem details. In other words you will essentially have the most critical elements of the lofting, which will save you a ton of working time. And of course there will be construction details and notes. It will be a large plan set, but that’s to be expected with a boat like this.

How difficult is she to build? She's a traditional boat in that she's initially set up inverted so that the bottom can be installed easily, and then her topsides planked. Her bottom is 18mm thick with 2 layers of 9mm aft and 3 layers of 6mm forward, planked diagonally. Her topsides are lapstrake. Once righted, her floors, frames, and deck are readily installed. 

She can be as plain or as fancy as you wish. The lines have proven themselves through her owner's thorough testing. She wrote:

I basically needed a very safe, stable boat I could get in and out of easily (two replaced knees and major arthritis everywhere else forced me to stop sailing my Herreshoff 12 1/2), that I could run by myself but that could accommodate four people comfortably, that I could run up on a beach, that took serious wakes from lobster boats of all sizes, that was self bailing, that would take me on trips to various harbors besides Camden, that was forgiving if I hit a dock while trying to land, and that was easy to run.

So Walt built me “End Game” and I have been out in her every day last summer and plan to do the same this summer, with and without friends although I find people asking to come, even at 8 am when the launch starts running!

“End Game" has a center console and a self starting (no cords to pull) 25 HP Yamaha motor. I get on the boat, warm up the motor, cast off and am gone in less that 5 minutes. The boat has an automatic bailer on one battery which recharges with solar or can be switched to charge off the engine, and an engine battery. She has two 3 gallon fuel tanks which can switch back and forth. I don’t need more than that but you could put in bigger ones. Coming home putting her to bed takes about the same amount of time. So it’s easy with maximum time out on the water rather than messing around trying to get underway. It is also simple. I have ever run a power boat in my life until now.

While I live on the ocean, the boat is on a trailer and would be perfect for lakes. She is wonderfully stable so fishing would be easy, and there is plenty of storage for camping gear and the like. Obviously you would customize it according to your needs.

I can’t say enough good things about my boat! I live in Maine, and the summer is very short with a lot of winter and a lot of snow. i have railed against winter for the 20 plus years i have lived here every winter except this one. This year I have been able to smile, remind myself that winter will pass and May 20 when launch service starts “End Game”will be in the water and life will be good again!


For now we'll leave you with these photos–under construction and another outward bound from Camden Harbor.






Her plans are black line prints, and the cost of shipping anywhere in the US is included.
