Well here's a a pic of what I refer to as a rocker. Would I be correct? Also I would assume that it only helps out when coming on plane and after that I would think has no effect being its out of the water?

ff,
do you mean the tabs??

rocker is- curve in the boat hull. ie. think of a rocking horse.
front to back.

hook- is just the opposite. ie. same rocking horse with the rails on upside-down.

Hook (noun): The shape of the hull where the bottom is concave, rather than at or near the transom. Opposite of a Rocker. A hook can be caused by insufficient support from the Trailer, failure of the Hull, or actually designed into the hull

Rocker: The shape of the hull where, rather than being flat it takes on a convex shape. Opposite of Hook. Can be caused by insufficient support from the trailer or failure of the hull. Almost never an intentional design characteristic of the hull.

bbladesprops,
It was Ron that I have been dealing with. If I get a chance Friday I give you a call.
Thanks,
Mike

If you look closly at the hull right behind the tabs about a foot foward you'll see that the chine starts to get smaller as it goes back to the transom.

Active Mike, ok call when you have a chance.

insptech, I would try turning them in as an experiment. Then I would Lab Finish the 26's.

bbladesprops,
I didn't forget about you. I have been swamped during the week and have had no time to call. Can you be contacted on weekends?
Thanks in advance,
Mike

We have a 2000 Checkmate 259 Convincor. Although I have never measured the bottom to confirm it's convex shape, it certainly looks like it has one sitting on the trailer. I wonder if this was an intentional design characteristic of this hull?

i don't know for sure, but it's not usual that the manfacturer puts a rocker in the hull.
sometimes they intensionally put a hook (convex) in a boat to keep the bow down.
you can take a straight edge 4' to 6' long and hold it to the bottom of the hull.the straight edge needs to be very true, because anything more than a 1/4 gap between the straight edge and hull is a hook.

Active Mike,

No problem. Call whenever you get the chance. Saturdays are mostly spent on the water. However this time of the year it gets cold around here. Try anytime and if we don't answer, we'll get right back to you!

bbladesprops,
I'll see how the week goes. If not I'll try this weekend.
I want to pick your brain a little on this prop.
Thanks,
Mike
