Interesting topic. I have not read all the posts in detail but there may be another small aspect to keep in mind - Units. This observation may be...
a cored hull can be 'moulded' Sail boat looks like a pretty old boat - mid-60's
One method I have seen & used: You can estimate the price of similar type boats(hull forms) using the "cubic number" which is L x B x D (length x...
maybe it is treated wood from old growth(virgin) forests.
This may seem totally 'out there' but consider lightning protection. Appears the panel is adjacent to a chain-plate & there is no ground strip...

4 swinging people cruising on a 40' boat, this appropriately describes how the cabins can run....... AMOK
Adam, you might also want to check out any regulations/standards you have to comply with (USCG, ABYC, etc.) as well as insurance.
Not familiar with this alloy but there may be other items to qualify/disqualify this boat. First build ? (is builder experienced in...
