I would be very surprised if he actually sprays Teflon on his hull. I have never heard of anybody doing this. The only reason to do so would be to keep something from adhering to the bottom and if the boat is dry-sailed, that would not be an issue.A friend of mine, who owns and skippers the boat that won major races repeatedly here in Maryland the past several years actually sprays his bottom with Teflon.
I beg to differ. While I am no fan of ablative paints, a diver who knows what he's about will be able to clean an ablative bottom properly without scrubbing off too much paint. Yes, paint will come off during the cleaning, that's the nature of ablatives. But depending on how frequently you clean your bottom, you can absolutely get normal lifespan from an ablative paint. And let's be clear, ablatives are no better at retarding growth than any other type of anti fouling and certainly need cleaning just as often.All the cleaning notes aside - Chose your bottom paint wisely, ablative paint is not conducive to scrubbing, all you get is cloudly water. Hard paint or no antifouling (on lifts) is the choice of speed masters.
