Such a sad thing to read. Wishing peace for you and your family, Bill. I went though the same with my father in the last couple months of his life, just over 24 years ago. The pain of grief lessens over time, but has never gone away completely. We all still miss him to this day.
I'd corresponded with your Dad about the site back in 2020, when IIRC he was transferring everything to a new host and the current board software. There were (of course) some transitional issues, and I wanted to let him know that if he needed help or whatever I'd be glad to do what I can. The offer stands, always.
I run several sailing community sites currently, along with a dozen or so commercial projects. Msg screenshot posted below, so you can see his humor.
