Yes, I liked sailboats even before K3. That's my very first photo on a sailboat, taken in the same club in Ipanema where I learned to sail later on.

The mono is a "Sharpie" class (plywood, hard chined, with a steel plate centerboard and steel plate pivoting rudder). They were relatively popular in Rio at that time, but not as much as other plywood boats, like Snipes and Penguins.

Cheers,
