My 2001 328 Four Winns I purchased this spring had Interlux VC Performance Epoxy applied to its underside in 2006. The previous owner boated in the Trent Severn waterways here in Ontario were antifouling was not much of a problem.
However, where I boat (Lake St.Clair and the Great Lakes in Ontario, Canada) we need a decent antifouling paint on our boat bottoms.
I called Interlux and the good news is most antifouling paints are compatible with the Intelux Performance Expoxy - that's a good thing.

I knew when I bought this boat that I would give the underside a good scrupping every three weeks or so to keep the bottom reasonably clean and I would then apply appropriate bottom paint next spring before launch.
I am considering applying Interlux Micron CSC or Interlux VC-17.
The Interlux technical help support claimed that at the same cruising speed (30 MPH) that there would be about a 500 RPM difference between CSC and VC-17. Meaning for the 30 MPH speed your engines with VC-17 would require 500 RPM less to obtain 30 MPH as compared to CSC. That to me is quite a significant difference over the course of running the boat for the season.
Does this claim sound reasonable to you? Would you have a preference between VC-17 and Micron CSC or is there another bottom paint that you would recommend for my boat being used in the Great Lakes area?
Thanks,
Mike.
