Price is a good one
If the boat is in good shape, that is an excellent price. You asked what to look for. Here it goes. Regarding wire rigging, make sure there are no breaks in the wires and check the studs. Also, is the wire stretched to the point that it can no longer be tuned. Look at the mast to make sure there is no damage. As for the boat, make sure it does not leak and if it does, make sure there is no damage as a result. The chain plates should probably need to be recaulked where the shrouds are attached to the boat whihc is only a cover plate held in place by four screws. Check hull and deck for and breaks and so forth with attention to keel where it is attached to the boat. As for the motor, running it will tell you alot. There is alot to tell you but maybe a good sailor locally who knows boats should go with you to look at the boat. If the trailer is a Kens welding or KWS, check the fender attachments, bearings in the axle and the board which the keel rests on.Crazy Dave Condon
