SD, have you any links to how such
seats are constructed? Obviously, it's not a wildly difficult task, as templates can be made from the existing plastic
seats, but I would like to see how others have handled attached the offset seat supports to the new wooden boards, and how the edges of the boards (which are also angled and rather thin) have been dealt with. I have considered that making a board with a through-bolted aluminum length of 1/4" bar stock (with appropriate clevis pin hole) would work.
I bought my 10' Portabote from a guy on this list, and I assembled it on the weekend but have yet to get it wet. Unfortunately, I forgot his assembly instructions and it took me half-an-hour of comical grunting, but I can see where I can cut this time in half. I believe I'm fortunate in that it's a lightly used "intermediate" model, with the wooden transom and the plastic
seats, so if the plastic
seats fail, I could simply make wooden substitutes.
I have a Honda 2HP four-stroke and I may put it in the water as early as this afternoon if the rain clears off. I'll post "results" after that. I do know that even inverted on the foredeck, it doesn't take up a vast amount of room. Folded up, it's really nothing lashed to the rail, or it would easily mount on the pilothouse roof.
