It is indeed a beauty that has obviously been loved but there are precious few who have the time, money or expertise to keep it that way. I grew up through the wood boat era and owned several from runabouts to cabin cruisers. As did my father and grandfather and uncles, whose boats I often helped with as a youngster. Don't let anyone kid you, they are an incredible amount of work to maintain, even brand new. If it has not been re-planked or the hull re-fastened in the last 50 years, it may look good but it is a virtual certainty there will be significant issues. Just re-packing the planks with oakum on a vessel that size would be a daunting task. You must, must, must, get a surveyor who is "intimately" familiar with wood boats.
If you read through the forums here you will note that a huge percentage of the posts regard repairing wood on our "fiberglass" boats, now imagine if they were entirely wood. I'm not trying to be a kill joy but just passing along "my" opinion and experience. Quite frankly I fear it will rip your family apart, not pull them together as you hope.
