I called the next owner of my boat after the sale and provided him with (hopefully) helpful information on my planned upcoming projects (ie: things that should not be left too long undone) as well as walking him verbally around the boat to alert him to things that he might take a while to figure out.
That's great! I still feel bad that I wasn't able to do this with my last boat, since it was sold by a broker who never even told me the buyer's name. He did let slip that it was being shipped out of state, so it's unlikely I'd see the new owner out on my local waters.
It's pretty emotional, passing along something that you've put so many years of sweat equity into. It seems wrong that I never got closure. Plus, I had a lot of tips and hints I could have passed along.
I still wonder how the old girl is making out with her new owners.
