I might also try the search functions here for PBO and Scuttlebutt. I suspect, in the day, either or both PBO and YM did a review of the vessel - and either or both magazines might be held by your local library ours carries Sail, so yours might carry PBO and YM.
There is a member of the forums that used to work for Northshore and its predecessor hopefully he may see this and respond, sorry but I can't remember his name.
Just be aware someone acquired the mold, or molds for Fisher yacht or yachts and a number were built in Mona Vale, Australia, about 5km for where we live. One was for sale recently, but single mast and 32' .
I see the occasional Fisher, they are very characteristic, but have no idea if they are UK or local versions. I also don't know how many models, LOA, were built here.
Here is a basic specification sheet for the Fisher 30.
You might like to join the Motorsailer group on Facebook (if you are a Facebooker) - there are a quite a few Fisher owners on there. Bei Facebook anmelden
