Hi Steve,

If it is mid-70's or younger, it is likely an all glass SailCraft of Canada boat. There were wooden boats built of that age, but most were clear varnished, not painted like your picture.

If all glass, check the decks for soft spots...small area easy to fix...if extensive might not be worth more than $1k as you'll need to do a lot of work.
If it is wood construction and if it is not rotting/still light & stiff, it could be a wonderful performer.

My Dad co-ran Sailcraft in Montreal until mid-1970's and I grew up on these boats. If you have questions send them my way.
