Repairable, but being that I haven't heard from the fibreglass guy for three weeks I'm thinking I should've just bought a new hull. It's either going to be a horrendous bill, or he just hasn't had time to work on it. I'm hoping its the latter.

Unless you've got a pile of bits and pieces left almost anything is repairable. It's just making sure you don't cross that line of replacement vs. repair costs.
