Mike,
I applaud you for the trailer. I am envious, jealous, or whatever is the appropriate word for the fact that you did this project as a Father-Son venture!
I will point out that the "Dobbs Tilt Trailer" design is different than MauganH17's concept. I do think that the the Dobbs's's trailer is an elegant solution to many of the challenges presented to the wide catamaran sailor who needs to travel and launch a wider than 'leagally trailerable' catamaran.
It is very impressive that the golf course is close to the launch ramp. Has the club expressed any disdain in your using one of their golf carts to move your trailer around?

I love the Dobbs' Trailer and and am very impressed by your and your father's efforts and accomplishments. If and when I get a Tornado, I will certainly gravitate towards the Dobbs' Trailer design.
