Make life easy:
Their customer support can answer all your questions, tell you which product probably is best in your waters for your type of sailing, and they'll also mention the issues like stripping off all the old paint
, to make sure there are no compatibility problems.
Yes, their products are expensive but they do set a standard. Bottom paint
no longer exists, if you call it "paint" they get insulted and tell you it is a "coating". Which means $300 a gallon instead of $50, but that's just what it is.
For your boat, you'll be buying
one gallon, and probably finding that's more than you need, in which case just throw an extra couple of coats on the leading edges of everything the bottom of the keels. You can probably get creative with some rented jacks or jackstands and some sawhorses made of 2x4's or 4x4's to lift
the boat off the trailer
and move it back-and-forth enough to get easy access to all areas of the keels. In the worst case, you find the cheapest local yard and ask them if you can do an "overnight haul" in their boat lift
. At the very end of their workday they'll rig slings under it, lift it, and tell you to finish up before the morning. First thing in the morning, they'll drop the boat again. On your trailer
or in the water
If the paint you choose can dry in under an hour, you can also do a "lunchtime haul" which is the same thing but done during their lunch break.
Meantime, the slings have gone on accessible areas, and you're able to paint the areas that were inaccessible.
No big deal.
