does a waxed hull increase speed slightly
 

would a compounded and waxed hull make any noticeable difference in speed maybe 1/2 to 1 mph or is it just for the fish to see themselves better.

Years ago I used a high silicone wax on the bottom and picked up about 3 mph but it was short lived and was a bugger to put on. It was so slippery that I made the mistake of using it on the deck and you couldn't sit on it without sliding off.

Nope! Wax actually causes and water adhesion condition which slows you down. Just take 1500 grit sand paper and do the contact areas and you will see an increase.

Tinkerboater,

What was that wax you were using and how short lived was it? For 3 mph I might be willing to put it on once a week. :D

It was years ago and like I said it was a very high silicone ( WAX ? ) All I know is it worked great.
In later years I used VC- liquid speed but it is now illegal due to the fact that it had freon in it. I still have some and I put it on my outdrives and it does help. Regular was on the bottom of a boat will slow you down.

There are a few of those speed coats out there now, and they guys are correct, a pain to put on. Wax will slow you down.

sand ,sand ,sand

Sounds like I'm going to be sanding. :D

They sand racing sailboats, it that tells you anything...

I know you guys hate them, but if anyone knows how to make a hull faster, it is a guy who is racing sailboats;)

Thanks all

Yeah, if a blowboter can pick up 0.002 mph, then he's KING.

huge difference between a displacement hull and a planing hull.

Here`s what I am wondering:
If sanding the hull reverses the effect of water adhesion, (a concept I understand and believe) then would it give you better results the bigger the hull you have?
I have a 22' Baja hull with 21* deadrise. If I sand the contact area with 1500 grit, will I actually see as much of a gain as say a person with a 29' Outlaw with a 24* hull?
With my hull, how much could I realistically expect to gain by sanding? Give me realistic numbers......:crazy:

Cool thanks guys for the tip. I'm on my way to Home Depot for sand paper. Now should I sand in a bow to stern motion or port to starboard?

Thanks

Hahahahaha.....somedays that is true!!

F31...yes, in some ways, but what i am getting at is with less power friction becomes a greater obstacle or hinderance, generally speaking. We are talking about the same issue, no matter the hull....how to reduce the drag/friction/negative energy of the water rubbing on the hull.

Certainly other variables, but the premise is the same...reduce friction.

I know a guy who syas he picked up 4 mph on a 31AO with big power by wet sanding the hull.

Why don't more people do this we ask??? I don;t know. My guess is appearance.

Donman...this is only a guess, but I would say you might pick up 1mph or so. Having never done this to a power boat, I do not know...an yes....I do race sailboats from time to time... :D

R....we sand ina circular motion in no particular direction or start/finish area.

I may try this later this year....see what happens.
