Unfortunately the Internet Archive only takes snapshots of a small number of a site's pages - you may be lucky and find what you want but I'm stuck with a few dead-ends! Alas Jim's excellent resource is not available any more. [The Boat Listing is now a separate matter hosted elsewhere and seems to need updating.]
However, the domain could be reinstated if he wished but the hosting of the incredible amount of information will need to be funded, although not too expensive.
I guess the 'gift lies with Jim' and if he is sadly suffering ill-health - this is the last thing he would want to be involved with. Hopefully a friend with like interests might be prepared to seek Jim's approval and reinstate it?
If nothing else, this certainly serves to make me think about legacy consideration for my websites.
