Shown below are the fine cracks in the interior starboard near-waterline area where there's a minor partial bulkhead (not the tank bulkhead) on USA 125, Black Magic.
The crack may have resulted from an old patch that may have been disturbed and might be a layer that's flaked off from other layers of fiberglass. CA says it's weeping slightly. It may be possible to re-balance the boat to move the crack above waterline to work on it; otherwise we'd have to haul USA 125 onto her trailer to do the work. The exterior hasn't yet been surveyed to see if any damage is evident from outside. A big question is whether re-patching on the inside would do for now, or whether we need to do a complete re-patch now.
