Here are a couple of videos (below) from Expandacraft. They offer a clear display of how the commercial hulls can be used to create a unique small trimaran.
We’ve talked about Expandacraft here before: http://smalltrimarans.com/blog/building-double-outrigger-canoes-using-expandacraft/
The first vid is an explanation and the second is a short demonstration. Thanks to Tony Waterman for sharing this video with us!
