: If my sometimes foggy memory serves me correctly, I believe

: folders.

Ah, yes. As I said, more expensive (add $400 to their regular price for transparent bottom only on a double folder).

: They are designed to be easy to build, and build times
: should be well under 100 hours. That varies from person
: to person.

LOL! Like people should be able to build an S&G boat in 40 hours? Well, maybe!

: Here is a link to a double that can also be assembled as a single.

Yeah... I really like the single/double concept... But... Well, how difficult would it be to add a child-sized hatch between the cockpits? And then... Could any of your designs reasonably be made to work this way? As in, you wrote just here in this very thread that this boat is your favorite so far. Well, fine. If I could make -it- into a single/double... Hmm. Maybe there is little to no advantage to doing so! You wrote that it's not the frame that takes the most time! Yeah, well, we'll see, we'll see!

cheers!
