Hi Phillipe
Welcome. There is a lot of information around here. Check the resources page on the main site.

I started small as well, O'day 22, sailing around the Bay. This year bought a Wilderness 30, an 80's racer. First boat with a spinnaker so lots to learn.
I sailed in the Singlehanded Farallones race last week and had my first OBE (overboard breakfast experience)
Seasickness and fatigue prevented me from finishing the course.
My plan is to go out more to try to adapt to the motion. I would be glad to call or email you if I am going out. Generally a couple weekends a month. I sail out of Richmond.
