Title: Rogers style bottoms
Post by: steves86ta on February 23, 2016, 06:51:06 PM

I know there are lots of boats out there with a Rogers bottom or at minimum a splash of a Rogers.

Mine seems to GPS higher mph and feels faster in rougher water.  In glass it seems to lose about 3mph and just doesn't feel as fast

Could be,  that the engine is up to a better operating temperature by the time I've messed up the water.  Just thought I'd ask for other opinions and input

Glassy water has a lot of drag vs a light chop keeps the bottom aerated. Less wetted surface

That explains it. I didn't know that

About the only bottom design that works in glass is a hydro or a tunnel.  We used to block the bottom of the race boat with 60 grit sandpaper to simulate riffles. True story.
