Hawaiian Chieftain is critically under crewed at the moment and is willing to take on crew with no tall ship experience. (If “running away to join Chieftain’s crew” is a little spur-of-the-moment for you, both of Grays Harbor’s ships are accepting applications for 2018 jobs.)
I can’t recommend working with Grays Harbor enough. Their boats are welcoming, supportive, and a ton of fun. If you want a look at what it’s like to start with zero experience, you can read my comics all about it!
