With 8 or 9 ablative bottoms and only one hard, Teflon bottom under our belt, consider the source!!
IMHO, the switch to VC Offshore would be a major commitment in time (If you are a DIY''er) and money. First, ALL the ablative needs to come off. Depending on the age of the boat and number of coats this can take some time. The residual amounts of the ablative varies with location on the hull.
Secondly, although you would not know it by the price, Interlux gives you far less solids and a lot more solvents in each gallon. You must apply more coats to allow the solvents to flash off and not get entrapped in the paint (excuse me, coating, justified by price, again). The actual application of additional coats is not that bad, save for raising and lowering of supports on the hard.
Then after spending all this time and money, you burnish half of it off!!!! A little exageration, but not much. VC Offshore is very hard and is easiest to wet sand. We started at 400 grit, 600 and finally to P1000. We used a pneumatic orbital.
If you stick with it, next year will take about half the labor for the refresh coats, again, a guess. In similar water temps, we get 2 to 3 years. But we don''t have barnacles, only algae.
For us, the results were noticeable. We now have superior boat speed against the other O30''s in the fleet and have climbed a couple of notches in the PHRF fleet. If we lose, which is seldom, we have no one to blame but ourselves.
