Boat Gps Speedometer
Boat Gps Speedometer
Does waxing the bottom of a boat make it go faster?
I tried that many years ago on a boat that didn’t have a speedometer, and that was long before GPS. It felt like it went faster, but don’t know if it was just in my head.
boat wax will not make your boat faster except to the extent that it helps to keep the bottom cleaner for a short period of time.
there are special “speed coatings” containing teflon or other chemicals that help to make your bottom slicker. the fastest bottom is a surface sanded with 400 to 600 grit sand paper.
boat wax repels water (that’s why water beads up on a waxed surface) for a faster bottom you want a sheeting effect on the bottom.
this boundary layer of water on the bottom is much faster.
this has been a subject of much research and experimentation for racing sailors. in the America’s cup small ripplets on the bottom surface was even tried to help keep the boundary layer of water attached to the hull.

Promised Land [CD-ROM] Queensryche’s follow-up to the double-platinum Empire is something of an acquired taste, but it’s well worth the effort. There’s considerable variety here; the heavy progressive-rock of “I Am I” and the ballad “Bridge” were hit singles, but there’s also the funk-inflected “Disconnected”, the edgy, spooky “Lady Jane”, and the piano-and-vocals “Someone Else?”. The title track is probably the stronge… |
