Waxing a fiberglass boat below the waterline?

[camzak]

I recently heard from someone that you don't want to wax a fiberglass boat hull below the water line. Any input to this? My opinion has always been that as long as it protects the finish and looks better waxed, why not do it? Thank you for your comments.

No, you don't. It will slow you down.

Damn, and I thought it made the water bead up thus making the boat go faster. Must be physics or something.

I heard from the speed boat guys that your supposed to wax down there....huh who knows....I got paint.

I think its fine, you really would want to do the water line to help wash off growth. Good luck. You should do it when the boat is out of the water, good rule of thumb..... LOL

I usually do, although not on the boats I have now. I couldn't tell a difference in speed on my old boats that I waxed below th e water line. Hotspot is correct though it can slow you down. I raced sail boats for many years and we actually pulled the boat and rough sanded the bottom before cup races. The sanded bottom produced tiny air bubbles that aided in speed. This was very important since fractions of a second count when racing.

Been wondering the same thing. Sounds like the below-waterline-waxers have it. Hard to imagine how it could slow you down much, if at all.

Well, i have been racing all my youth international sailing dinghies regattas, and for sure we were all waxing as often as we could to keep it smooth and fast. We may have all been wrong

I thought all sailboaters waxed their hulls , guess i was wrong

I my boat bottom is not painted and I keep the boat in the water for a few weeks at a time therefore I plan to wax to reduce growth and make clean-up easier. Is this a mistake?
