Fixing a leaky keel/hull joint is a major endeavor. Such leaks are frequently caused by the keel hitting something underwater. The forces involved often jam the back end of the keel up, damaging the hull there, and levering the front of the keel down, opening up the seam between the keel and hull and often damaging the hull or floors (ribs) that the keel is attached to. A proper repair usually calls for removing the keel from the hull, repairing the hull where it has been damaged, and then re-seating the keel to the hull. Getting the keel off will be essentially impossible if you are planning to beach the boat at high tide and prop it up on the shore. Taking the keel off will remove the main support that is holding the hull up. The stands that would be simply holding the boat balanced on its keel will need to actually support the hull. You would need to dig a hole under the keel so it could separate from the hull. The stands would tend to sink into the shoreline mud as the tides came and went – making the entire structure unsteady and prone to falling over.
It might be possible to do a “quick and dirty” fix by simply wrapping or covering the entire hull/keel joint with fiberglass and epoxy. This might stop the leak temporarily. But, if the keel/hull joint is damaged from a grounding, the keelbolts may not be holding the keel firmly. When the boat is refloated every wave that hits the hull will cause the keel to swing from side to side a little bit, like a pendulum. The keel on this boat weighs more than a ton; an epoxy/fiberglass band-aid wrapped around the keel/hull joint is not going to keep it from moving. The movement will end up breaking the epoxy/fiberglass joint. The leak will return and if not repaired properly the constant flexing could end up weakening the keelbolts enough that they break, and the keel falls off. This is why people with leaking keel/hull joints remove and re-attach their keels.
This boat does not appear to be a good low-cost housing option.
