Sorry to here about your parents
I lost my granddad back in October and he was the one who passed this boating sickness on to me! I was still in diapers when he was building an Ian Farrier Trailer Tri 680. He also took me to all the boat shows when I was a kid, bought me ship models to build, gave me all his naval architecture and boat building books...
But that plywood trimaran, it started my obsession with boats...we went sailing in it, fishing off of it, I camped in it in his back yard on the trailer and played on it every chance I got. I wanted it sooooo bad hen he gave it to my dad but I was 16 with no money. Eventually it went to a fellow addict who restored it.
I still have the plans and had built a 1:10 scale model of it for Radio Control. Since he passed, I've toyed with the Idea of a 1:5 scale model.
I need to scan in some old color pictures of it.
