I had a "moma bob" that I'd use on Catalina trips. Painted it black though so it wasn't so noticeable. E/P made my spinn. It was small by 21se standards but worked great (300 sq. ft.) It was N20 profile. I'd just go with a N20 chute and be done with it. I ran a (short) 13.5' pole with mid pole snuffer. Spin sheet blocks were in the same tracks as the jib traveler cars but forward of them. I'm dissapointed you cut the rear beam but you could have a good welder drill some 1" holes just to the insert and plug weld them. I welded my beams so the boat was full width all the time. The stiffer platform sailed better. Trailering wasn't bad, just go through the far right lane when crossing the border into or coming from Mexico (it's for truckers). DON'T MAKE A HARD DECK TRAMPOLINE!! They didn't put Man O War in with the Budwiser Clydsdales.
