If that boat was called Island Roamer it was indeed Forbes Cooper's personal boat. Too bad that one wasn't any good.
Cooper got Vancouver started in sail with his production of Catalinas. I have seen reports that he built 1500 27s alone. He also put more Vancouver sailers in the South Pacific than anyone else, with the Maple Leaf series, 42, 48 and longer were all great world cruisers. I had one of his Seabird 37s. A great family boat. Mine was cutter/ketch rigged, so windward performance sucked, but otherwise it was a great boat for the time. Not too fancy, but heavily and competently built. I still carry a picture taken with the rail in the water, all sails up and drawing well, over 24 years after moving to the dark side.
In the 90s Cooper was building Queenship yachts for a while, but sold out and started building the "Forbes Cooper" series of individual yachts. I don't have a good knowledge of how many variations on the theme he produced, but I did see him show up in a different Island Roamer every couple of years. Maybe they were all "his personal boat". I know that he was building into his 80s. At 87(?) now I doubt he is still at it.
