You ever hear of the Dumas company? Well they make scale boat kits made of wood or fiberglass. RC and static. The most interesting are there two PT Boats , one in 1/32 scale and the other in 1/20 scale.
The 1/32 kit is wood construction, and is 33" long.
The 1/20 scale kit, has a fiberglass hull with wood decking and cabin. its 48" long.
Now if somone wanted to build a large scale PT Boat, these would be a great kit if you are not a scratch builder! Oh, and the kits come with all the nessisary hardware, detailing and running guear. Yes these are RC'able models. There web link is below:
