On my previous boat I had an inflatable dinghy. That's ok, but I want something that rows better, as I prefer to not use the outboard.
My first attempt was a "portugese style dinghy" (see https://hvartial.kapsi.fi/dinghy1/simboii.htm). But I found it a little too small, and I gave it to my sister who can use it on her garden pond.
My second attempt is a "chameleon" nesting/stacking dinghy. This is a Danny Greene design, find his contact info at http://duckworksmagazine.com/04/s/designs/greene/cham/
Google or youtube "chameleon nesting dinghy" for lots of information and building experiences.
