Thanks Hank. That was before my dad entered the picture, so it must have been an ex-boyfriend, think he was American btw - Scandinavian blondes were also popular in the 60's ;-)
But you're right on the money when it comes to the value of nostalgia - while roaming through the same photo album I came across another photo of my parents sailing on my fathers 48-foot ketch (sailboat) from 1948. I managed to track that very same boat down on the internet and now it sails with tourists off Nova Scotia in Canada - so now I'm trying to put my father in touch with the current owners.
