a good analogy is pouring a little water on a waxed tile floor then droping a waxed tile shiny side down on top of the water . then trying to pick it up. wont be easy. flip the tile to the un finished satin side and it lifts .
same method or theory when wet sanding the bottom fore to aft.

montassa,

Your right with that and I guess it's relative to the size of the dimples. The porus side lifts easier because the contact patch is so much smaller than the smooth side.

I think the dynamics change when water is passing by something at 80 mph as compared to being static?

Only one way to tell make yourself a little test bed and video tape it, I don't know what will happen - maybe it works?

Debating a tech issue as you know only goes so far, you have make it and test it to get real data whether it is virtual or physical testing.

My first question is how fast is the package going to go? If you only go around 65mph, keep the motors low. Gains from reduced drag of high motor position won't show up until your around 75-80 +. If your going slower than that with a high motor setting, you will lose percentage slip and the ability to carry the bow with trim. That could make you slower.

all good points, the aeration would come from forward momentum, and waves...they are the constant...Bo, in your tile theory you are correct, if you left it flat side down, they only way to remove it would be to wiggle/aerate the tile with movement, then pick it up.

I agree..the 38 PP is an awesome riding hull. The 43 Sunsation, with the added proper step placement, araited, and with the GRAPHITE applied on the bottom to help reduce drag is an excellent riding boat and gives also one of the best rides in rough water that I've been on. Kudo's to Sunsation. Whom ever did the engineering on that hull did an excellent job, I call it like it is.

great,,,,,,,,,,,, now i have to wait for the egg nog to ware off and start spillin stuff on my wifes floor,,,

i have tried this theory, and it is good for 1 to 1.5 after the 85 mark. so in these cases it did work. i do agree about trying every theory before commenting on it directly.

Good point.

The dimples on a golf ball move the seperation point of the air from the ball, reducing turbulence and thus drag.


This was not discovered by scientists, but, by players noticing that their well dented gutta percha golf balls traveled farther.

I don't think it will work on a boat hull bottom.

surf boards have used dimples for speed for a few years now.
