Hi and welcome,
I don't know your sailing region but you'll almost certainly get a crew spot if you decide to get involved in racing
from a local club. Most people new to sailing assume its hard to get involved, but the reality is a reasonable sized race boat
needs probably 8 crew - and most skippers struggle to find crew reliable enough to trust. Don't worry about the lack of experience - that will come with time and some study - just get along to a few local clubs and ask around.
