Probably not Keith.
Epoxy as a barrier coat is not the same as "Hard" bottom
paint. Interlux 2000 is a barrier coat that should be applied to a clean and faired gel coat. The bottom
paint goes on over that. I would first find out what works best in your sailing area for folks that use their boats as you expect to. I use Trinidad SR and have been very pleased with it. Diver
hits it about every 60 days and it is fine for about 2 years. Haul, pressure wash, rough up and another coat goes a couple more years. Ablatives don't do well with bottom scrubbing because they are "soft" and disolve away over time. Hard bottoms are preferred by racers because you can get a uniformly smooth finish that stays that way as long as you keep it clean. Having said that I know some racers who use ablatives. Plenty to choose from and as with all painting...preparation is the key. Enjoy!
