anyone out there had any luck with hull/drive coatings??? i remember a couple of years ago there was stuff call vc liquid speed that was a teflon coating that you sprayed on the hull and drives-anyone tried anything like this???

speed wax is the best on the market, search for threads by littleduece, he invented it in a secret underground wax lab, iv e heard you can gain as much as 7mph depending on type of hull and how thick a coat you apply

I heard BIG SCOTTY fully endorses it!

There is a product out there called speed coat. It's a graphite based paint, it comes in rattle cans and quart cans for use with a gun. We tried it on an SST 45 boat that I crewed for a couple years back, We didn't see any noticeable gains at all. It was just kinda one of those we have to give it a try things that didn't work. About the only benefit was that the boat slid on and off the pit trailer easier.

7 mph ? SEVEN ? do you know how much parasitic surface drag over the small number of sq in of hull you have in the water at speed you are talking about there ? that is an absurd number... maybe POINT 7 mph

Rat was joking, look up some threads about littleduece and you will understand.

Yeah.

And hulls with blisters are up to 8 mph faster than hulls without blisters because they break the surface tension like a million little steps. Depends on the length of the hull and the amount and height of the blisters. This was why non-bagged 80s hulls are so fast.

You just have to be careful when turning at high speeds with a blistered hull. You could spin out.

This is where the expression "Blistering fast" comes from.

ah ha.... well... with some of these magic beans you never know when people are serious and who is believing whaqt fairy tale that day......

BUT as for the blisters.... i worked on some americas cup boat stuff where an unamed company developed a golf ball like surface finsh in micron size that , infact did reduce the parasitic drag by a real and repeatable number... and it WAS like little mini blisters... was worth real boat speed... but of course those boats have a lot of hull in the water all the time...

thats why you need to put thick coats of speed wax on, so its deep enough for the dimples

my aunt and her husband raced several olympic sailboats and they used that on all of them, dont know if it made em faster but they felt it couldnt hurt, i wouldn't put it on a go fast. talk to tres i think i read some where they sand the hulls with a very fine grit sand paper for less drag
