Prop Data On Moesly 21'

[Fr. Frank]

that hull has lots of lift and the reduced wetted area at high speeds reduces drag so prop slip goes down, or you achieved lift off.

Dave, you've nailed it exactly.
This is the beauty of the Moesly VDH hull. I actually got my slip down to 8% when I was running a carb'd Merc V6 with speed mods and a custom made PowerTech prop. That was pushing my Seafari at a max speed (in cold weather) of 54 mph.

Something I found on prop slip...

So with the current prop I have, there is a lot of prop slip.

More testing is needed when boat is done and fully loaded.
