Are the not legal because they don't come out the top?

1.6.4 (Added by vote, August 2007) For the avoidance of doubt, daggerboards/centerboards will conform to the following :
a) Curved/’Banana’ boards will not be allowed.
b) Assymetrical cross-section profile boards will be allowed.
c) Fore/aft movement of the boards when in the down position will not be allowed.
d) End fences/horizontal appendages below the waterline will not be allowed. The board shall be capable of removal, without tools, via the upper opening of the case.
e) There will be no limitation on the daggerboard/centerboard length

Part D is what I'm curious about. There's two statements there.

The first rules them out explicitly, the second implicitly.

If one had a straight board that bent enough without breaking you would have a curved board?

If it has a "bend" is it then not "straight"?

BEND [bend]
verb (used with object)
1. to force (an object, especially a long or thin one) from a straight form into a curved or angular one, or from a curved or angular form into some different form: to bend an iron rod into a hoop.

STRAIGHT [streyt]
1. without a bend, angle, or curve; not curved; direct: a straight path.

Something that can be done is getting a straight board with a smaller 45 degree tip down a cassette box if the cassette box is setup like the modern adjustible A Class style, with the addition of a small flap on the inside of the hull. A 12 degree incline + say 45 degrees gives very nearly the optimal board shape. Is the additional small end piece ( the bit that gives the vertical lift ) an end fence, not in my book.

I hope they leave this get out clause in there for future experiment with what is effectively L boards.

To rephrase, use a low mudulus material than that bends easily, and stays in the elastic zone to preclude a permanent curve/bend.
