Welcome aboard! I used to crew aboard a 33' Abbott on the Detroit River in Lasalle, just between Windsor and Amhersburg. My first
boat, a 16' McVay Falcon, was built in Mahone Bay, NS. I'm a big fan of Canadian sailing!
Honestly, the best place to learn is to visit a marina and volunteer yourself as crew. Many skippers prefer inexperienced crew so you can learn things "their way". And every skill you learn is valuable.
Best wishes,
Mark
