here's a thread on my install last year: https://forum.supraboats.com/showthr...highlight=trex
i'm going to be automating it in a couple weeks for automatic deployment/retraction as well. it works good though. to summarize: deployment angle outward around 12 degrees, surf side weight ~1300lbs, non-surf side weight ~700lbs, front 650lbs. this gives a very surfable wave out to around 15' depending on the rider.
'88 Sunsport, 2250lbs ballast, automated surf system, home made surf exhaust, surf flap, ACME 913, Krypt 6.5 HLCD's, Perfect Pass Stargazer
