Turning fins question?

[drbyrne55]

Stock runabout question....


rulebook:
2) No part of the immersed surface may have a negative dead rise. The immersed surface may have a maximum notch of 5/8”, and turning
fins may also be added to the immersed surface.

.... Dead rise: lift from the centerline or keel to the chine. Sometimes referred to as a V. An example of dead rise is the keel being 0 and the chine
being 1” higher. Negative dead rise is the opposite of dead rise. Negative dead rise is not permitted in any runabout. This is the case for both
negative dead rise from fore to aft and port to starboard


I don't see any specific language regarding the size (depth, or length) or number of turn fins or location of turn fins as within the immersed surfaces?

Can you freely locate turn fin(s) anywhere within the immersed surfaces?

Thanks
Dan

Post from another thread.......

I Agree!!! It it a fin or a lifting rail? Up to the inspector as it stands now. I am seeing a few CSR's with negative dead rise or concavity forward of amidships between the keel and chine. No one says anything. Guess it depends who you are or who built the boat.
