I think with all boats getting a good
survey is essential before
buying a boat. The windows in the older privileges can leak. We have planned to replace our but have not found anyone to do them yet. I expect the cost to be close to 5K. The
wiring is a nightmare if it is original. What were the french thinking? I expect that if you are looking at a 39 then you are looking at 20 year old boats. The
rigging should be replaced every 10 years so in theory a 20 year old boat is due. We had our
rigging redone with the boat in the
water and it cost $5500 ( including installation). We also replaced all the running rigging. That's about all I can think of right now. We have had pretty good luck with our boat.
Being a pilot, the one thing that makes me crazy about boats is the lack of
maintenance documentation. I had a 1940 airplane with logbooks from day one. I have no idea what
maintenance was done on this book and often feel like a detective trying to figure out when items were replaced. I am now treating it like I treated all my airplanes and documenting everything I do to the boat. If you could found a boat with good records it would help you in the long run.
