Fastest Checkmate Hull?????

[Jimway]

Hhmmm, "The combined effects of wetted surface, surface condition, surface length, and speed, comprise the resistance of fiberglass on fresh water and can be calculated" says Fast Eddie....

haha thats getting pretty involved, I didnt want to be scientific about this

 

[Jimway]

Then there is the "Boundry Layer" which becomes an important part of the rather complicated equation. Fast Eddie knows an awful lot about this stuff and he is pretty proud about explaining it out. I'm still workin on it.
You should see the equation without the boundry layer part......

So now I'm wonderin if all of the other various factors are taken into consideration, if what we are talkin about is how well a hull passes through the boundry layer. Stepped hulls and notched transoms come to mind, along with those little bugs that use thier long legs to skip across the surface(boundry layer) of the water.....

One way of measuring efficiency of a boat and it's setup is prop slip. The problem is it takes into account all factors involved in the boat's setup, not just the efficiency of the hull.

On this subject, I'd be really interested to hear the better prop slips calculated for the different Checkmate models.

define better? lower prop slip doesn't mean faster or more efficient...

and other variables, one obvious one is that depending on the hull, you get some aerodynamic lift, reducing drag, at the upper end of the speed ranges you're talking about...
