bottom fairing and paint
If I remember correctly you sail on a fresh water lake. I would think that you need minimal antifouling protection. Baltiplate and VC 17 are generally seen as the best racing finishes and should be adequate for fresh water condtions. As to fairing or barrier coating. I like WEST Systems or MAS epoxies. International Paints also have a very good barrier coat system but I have never actually used any of that product system myself. WEST System had a very good monograph on fairing bottoms and keels.
