Those folks gently warning you are quite correct. Your plan is plain CRAZY.
Let's see: a newbie sailing a new-to-him boat across treacherous waters? Hmmm... Might want to think really hard about this.
I had a C22 in the early-mid 80s. We had heavy winds in the sheltered California Delta
, winds behind us and we got whipped. And we were at your level of knowledge back then.
I wouldn't do that in our C34. Some may have, who know the waters and the weather
, a LOT better than you've exhibited.
You really need to get to the point of where you don't have to ask this question. Then, and only then, you should go.
Get some practice in, and you'll answer your own question.
