Sailing experience does not work like that. You could sailing every day for six months and have a nice every day and not learn a fraction of the things you would need to know to head offshore. You learn when things go wrong, not when they go right.
Find someone to crew for to Hawaii or somewhere else (Mexico?). There is so much to learn and it can't be speeded up that much - that is one of the joys of sailing. I have been doing it for more than 40 years and still am constantly learning. Did not go offshore (NYC to Bermuda which is less than 700 miles) until I had about 20 years under the belt.
Finished the circumnavigation in early February in Grenada. Have to work on a book project for the next several months so the boat will be waiting for next year.
