Can you supply a more detailed description of this power-tri?

Was it like a sailing version that had been converted to power, or
specifically designed as a power-tri?

Was it a 'beamy' tri configuration? with big amas??
ETC?

High You All . As to the question about stability of a power
trimaran--four years ago I rode on a 50 foot Tri from Naimo BC to
Alaska during a predicted log race. The boat was unique, home
built, powered by a GM 350 Gas V-8. It did have one big
drawback--When an Ama caught a wave the boat would turn and then
the other ama would catch a wave, etc, etc,. The autopilot could
not keep a coarse within 10 degrees! Dave sends.

Sounds like the rudder was of insufficient size to hold the boat on
course without yawing.

Brian,  Yes Brian,  the Cat was a Kit Built sailing cat without any rigging.  When I rode this cat it was it's second trip to Alaska and was at least 5 years old. Actually it was an impressive boat except for the steering.  Since it was a sail cat  I doubt if too small rudder area was its problem. I don't know who drew the plans.  The tri had a wide beam and broad amas- at least  5 feet. Dave
