I have noticed a crack in the rib behind the battery. It is not compledly across the entire sturture but about 2 inches long. Can these be repaired? Can an owner do it or is a boatyard needed to accomplish the repair?

A crack in the rib itself or has it delaminated from the hull? Delamination is what is more often seen, though in either case you could repair it yourself if you're handy with fiberglass.

Do you have a picture of it, or any more details?

John

The exact same thing was missed by surveyor on my Laser 28 purchase 5 years ago. It is caused by grounding the boat, in my case one of the previous owners - email me for photos and details of my repair if you wish, it's easy enough to fix if you're handy with fiberglass, but use e-glass if you can.

Hi John,

Hope the weather in SoCal is as nice as here....

George is right on with the grounding of the keel. When the boat runs aground that battery support beam goes into compression and can snap or crack. Since yours is cracked, the gluing flange underneath is undoubtedly unbonded, as Paul mentioned earlier in the thread. Best fix is to cut off all surrounding gluing flanges to the hull and then glass the entire beam into the hull laminate. Most important is to be sure all areas are dry, clean and well sanded with an 80 grit before you begin glassing.
