I like the general idea for several reasons. I looked at the folding boats and have see all the positive comments, just too expensive for me and the size of my sailboat right now. I have a Zodiac that I got used at a really good price, but at 10 feet it is too big to stow on my boat (I will only be using it to motor to my mooring), with a wood floor it is too difficult to set up on deck. If I could have found a used 8 foot Zodiac with the high pressure floor it would have been the better choice. I realize that with an inflatable I run the risk of tear/puncture that many people note and I would really hate to see my expensive outboard go into the drink!
I really like the second link dink (haha). The honeycomb core and S-Glass make for lighter construction but I find it puzzling that it comes in at 99 pounds complete. I used to build cedar strip canoes and kayaks as a teen and they were very light, but yes, very different construction types.
I had an idea years ago to try to simplify composite foam core small boat construction. Basically I would build a simple 4x8 vac table and do a run of 4x8 sheets of foam core composite sandwich. The completed sheets could then be treated almost like plywood in the construction of a small boat for either stich and glue or traditional plywood boat building methods. Just the same, why couldn't I make my own folding boat in this manner as well?
Someday I hope to explore this method fully and build a folding boat or nesting dink in say the 8-9 foot range with a good balance of speedy to stable hull design. I'd like to do it in Carbon with a goal weight of less than 60 pounds. I'd like to be able to easily assemble, launch, and recover the dink from a single arm davit with the outboard mounted. Seem reasonable?
