233 hull shape

[resurrected]

I'm in the process of trying to blueprint my hull, I've found it has a lot of rocker. I don't know if it's original or if when the stringers were replaced prior to my purchasing the boat caused the deformation. If anybody has access to the bottom of their 233, I would like to hear what shape it is, any input would be appreciated, thanks.

You talking about the "downturn" at the stern? If so, that is on every F233 hull that I have ever seen.

No not that, I mean if you hold a straight edge parallel to a chine, foreward from the transom, at what point does it lose contact with the hull?

Like this!

All I know is a formula233 has a lot of rocker built into the hull. That is why it needs those down turned areas at the stern to push the bow down a little to compensate for trhe rocker. What this does on the water is the faster you go the less boat is in the water making it a fast and easy boat to push for a deep v.

Yes it does have a lot of rocker.....now I gotcha. Looking at mine on my bunk, you can see it.

I dug thru some pics, you can see where the strakes "leave the bunks"....

Actually, it is tough to see in the pics once they are resized smaller :-\ If you look close enough you can see it....

Thanks for all the pics, it's a relief to see, I though the guys who did the stringers before me caused some problems.

The rocker in the 223 hull is for bow lift. My understanding, is that the early props did not have much bow lift characteristic.
