James Baldwin, dual-circumnavigator and owner of the Triton "ATOM" has a small plywood pram that is designed to combat the size and stowability problems. It's built with the stich and glue technique and is about 6.5' in length. Check out his article at:

This dinghy actually looks usable despite its small size.

On our Triton we have an 8' Fatty Knees that will just fit on the foredeck if need be. It's definitely awkward. We usually tow it.
