there is a warped looking place on my 1975 23 larson.its right on the top chine and about half way back.if you layed a straight edge along the hull there would be about 3" or so of warpage inboard and its on both sides of the hull.ive been under the floor there and the wood all looked good.the gelcoat isnt cracked or anything.so what could this be?also have 1 place on the chine at the bow that is doing a little spiderwebing.could it be what is called a hard spot?if so what to do about these problems would be appreciated.ALSO any info on old larsons design/construction/reputation <br />thanks!
