Does anyone have any opinions on the relative merits of keel strips for
sea kayaks?

I am about to buy my first glass boat. I am planning on getting an NDK
Romany.

On one had they seem like they might be useful in areas with rocky
shores. On the other hand, it seems that they would both add weight and
effect the hydrodynamics of the hull. Any help would be appreciated.

thanks,
