[C320-list] Club Racing the C320

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?
