The posts have confirmed general quality that available, but limited, research as suggested. This particular boat still retains its original wooden mast, however, it is in excellent condition with annual maintenance by current owner. Overall, the boat is in excellent condition, still has atomic 4, but also in good shape.
As info is limited for research, I was just wondering about general stability with the high cabin top and any risk areas on the boat to watch out for (will have survey done).
Wooden mast is a concern in the long run (great shape as noted, I inspected mast for cracks, etc., as mast is down for winter maintenance), but researching with local shipyard for estimate of replacement if the mast were to fail.
