ya bill. i know. i am a builder by trade. for some of these guys with boats that sail every two or three weeks on small lakes, i think the injection method works fine. the boat probably will not see 15 knots, much less the conditions your super cats were built for. i do not agree with your statement as to the cost to build the boat right in the first place. i think it would be lower. scrap off cuts could be used and the 10 oz glass takes nothing to wet out. on the boat sprit of canada, we put a 10 oz on her hull to sand into. we did not wet it out at all. we just let the vacuum draw the resin through it and into the bleader.
