Waxing bottom of boat
 

I had a little time on my hands and while waxing the boat decided to crawl underneath and wax the bottom of the boat. Hard to appreciate all the work that goes into the Fountain hull design until you spend a little time under her! Anyway... my question is do you think waxing the bottom is worth any increase in performance? Wonder how long it will last... Any racers doing this? At the very least I got a good arm workout -:)

Actually its said that it slows the boat down. I have never noticed any difference though. It looks better shiny.

Same, here - never noticed anything. Also easier to clean off lake scum. I think ambient air temperature/humidity on any given day has more effect on speed than waxing the bottom.

Bob, I know you are correct on the air temperature. It's something like a 1% increase in horsepower with every 5-10 degree drop.

Well, as mentioned, I did get a great arm workout and a new appreciation for the steps and pad setup on the Fountain.

i heard rainex sprayed on the bottom of the hull works pretty good. may or may not give any speed but seems to keep the scum line off a little better

What he said. Rain X is the chizzz...

Yes, you can see the extra work they put into getting the edges sharp and surfaces flat in the last several feet of the boat, usually from the step back to the transom, when you are laying under it for a few hours :D

did you ever gps it and see if the rain x ever gave you any mph??

No. But being in the paint/detail business I have not found a better product to keep crap off the hull.

The racers generally tend to lightly sand their hulls for less drag....
