Nope, you're out of luck Jay
.....not a Trawler rather a "Fast Fisherman" according to their advertizing........of course the "Trawler Yacht" term hadn't come into popular use back in 68.....
The Romany 21 has been a favorite boat for many years, I think since I first saw them advertized. Surprisingly I believe there is at least one other in BC, it has Isuzu power (perhaps 6 cylinder?) and a towpost, used to be around Ladysmith.
Amazing they mention 18 knots, which seems unlikely with the stock engine......Oh and don't expect the advertized 47 cents per hour cruising.....
