This regatta fabric has alot more boats, but the print looks similar, maybe it might help you further in your searching.

This one really looks like the boat, but you'd really end up having to chop alot of holes here & there.

Tara Reed looks like the designer and SouthSeas/Wilmington, however I've searched for the Day at the Beach and can only find her more recent ones for sale. Hopefully someone else can find something for you.
