"Why would anyone design a boat with" Damfino, it wasn't on MY watch.
Could be someone said "We've got a stock rudder that will work for that design" or even just "Yeah, we can make a shoal draft version of that." Then again, it might be part of the same french engineering that leads some folks to call them "BendyToys".
I like some of the boats...but overall I wish the French would stick to champagne and cheese, they do THOSE so nicely. Coq au vin, lots of nice things from France that don't need machine tools to make them.
