Came across it on the internet, it looks like it was a manufactured boat.
Vacuum formed hulls maybe???
Hi Bill - it’s an old 36/600 class trimaran. The one (and only) AMYA recognized multihull class ! Circa late 1970’s - early 1980’s as I recall. A collector’s item - but not worth the effort to make it R/C since they sailed awful. No wonder everyone has misconceptions of the multihulls. !
