Re: Hull Blueprinting
Cay,
Why do you think the 292 and 311's don't have a hook. The 272 should be faster than a 292 with the same power right?
It seems that the lighter 272 would be faster than the 292 but aren't. The 292's don't have hooks. At least the 88 thru 90's that are on my lake don't.
What do you think?

mtg,
Not sure why the 292 would be faster but it could be something simple like the x-deminsion or the strakes might be different. I installed IMCO 2" shorties and picked up 4mph even going from a 3 blade prop to a 4 blade so if the 292 has a higher x it could easily be as fast or faster.
If I don't decide to sell my 272 I plan to try extending my inside strakes and possibly installing a pad in an effort to take it over the 100 mark.

Re: Hull Blueprinting
On a V-hull a strake or lifting strake is usually about 3" wide starts at the bow and goes to the stearn of the boat. On many hulls the strake closest to the center stops a few feet short of the Stern while the one furthest away from the center usually runs all the way. The chine can be thought of as a strake placed at the outside edge of the bottom. In the case of the Formula 272SR1 they have a wedge (similar to a built-in trim tab) between the outside strake and the chine. Hope this answers your question.

Becareful removing the hook from the 251 Check.. I did it and it caused some serious handling problems.. Give me a PM and I will explain. I have posted this info before, so a search may bring it back up..
