Other stuff I've recently discovered....

Took a wander down the coast over the weekend to a little hole in the wall place that rotomolds canoes/kayaks as well as building carbon versions also.

The big surprise was a. that he reads this forum and b. he can build rotomolded boats that are 18' and are only 1.7 kg heavier than the same boat in carbon.

As you might guess....he wouldn't tell me exactly how its done, but they are almost as stiff as the carbon hulls and he can whack them out extremely quickly (4/day).

Seems the trick is that they have a very thin outer skin, a honeycomb core and then another thin inner skin....also has metal inserts for fixtures and he says he can mold centercases in at the same time if required.

This may be the way forward for cheap and lightweight boats for the class, and I intend to pursue this to see if I can't get my round bilge design done this way if the setup costs permit it to be accomplished.

Cheers
