Yes. Cracked aluminum hulls and torn transoms are common in fishing boats that have been worked hard. We weld the crack with proper prep, often adding a doubler plate where the load needs it, and the boat goes back in service.
Severe damage like a hull that’s been holed open or a transom that’s rotted through where the wood core failed needs more involved repair, sometimes including replacement of the affected section. We give the honest call before we start.
