A very odd small trimaran indeed!
Sailing friend Ian McGehee shared the following links with us a few days ago. They appear to promote a small tri that is no longer in production.
As Ian notes, however, we can document it for historical purposes, as it certainly is an odd design. Many thanks to him for taking time to share this find with us here on the smalltrimarans blog.
