Re: what is the function of the keel stringer?
Yet another season has passed. Now that we have a lot of time on our hands, why doesn't someone volunteer to cut (LT) the keel stringer out of their hull, put it back together, take it out in 8'-10's and let us know if you can tell the difference. Video would be helpful...

Re: what is the function of the keel stringer?
The keel stringer supplies longitudinal stiffness to the hull. It is often utilized as a connecting point in larger boats as they are often made in 2 halves and bonded together - the keel stringer adds another bonding point. As stated in an eariler reply, the wood does not supply the stiffness - it is the geometry. The taller the stringer the stiffer the the boat. Often they are hollow. The wood was a simple way to preform the glass materials. The only place stiff materials are required is on the top (stringer cap).

Re: what is the function of the keel stringer?
Potter tells me the wood keel and the later pvc was to stiffen the area because most trailers were using rollers that would stress the keel. [img]images/icons/grin.gif[/img]
