purchased a 1988 35 legend with what I thought is a factory cradle. this year the aft starboard support caved the hull in and possibly cracked the hull. Does any one have the factory info on setting up the cradle? Does the keel support the boat and the supports just keep it from falling over? How far forward or back on the cradle does it sit? It appears the aft support is between the inner ribs and does not support the hull. Thanks for any info.
