[C320-list] Club Racing the C320

I never heard of anybody putting antifouling paint on their prop before.  Is
this a widespread practice?  Nobody around here (Lake Ontario) does that so
maybe it's needed in the warm waters of the sunny south?

Thanks.? I used PropSpeed this season also and will haul my boat this week
to have a look, but it's awfully pricey.? A couple of years of PropSpeed
would pay for a Kiwi prop and some bottom paint.

"How well does the Kiwi hold bottom paint.?"?
The Kiwi prop blades seem to like PropSpeed over the normal Ablative/Hard
antifouls.? In Australia a lot of us are using PropSpeed.? PropSpeed holds
over a 12 month period very well.? Ablative Antifoul will come off the blade
tips.? Some put on a Hard Antifoul (2 coats) then add 2 coats of Ablative.?
This sees them through to a 12 mth period? ? Bruce Stanley / Sydney? ?
