Well after highly considering getting my first boat, the fact is I just dont feel safe by myself. I'm glad there is such a positive consensus about sailing solo but I just can't have peace of mind by myself.
Goodness! There's as much discussion since you posted that you're giving up your dream of getting a boat as there was (most) people trying to give you the confidence to sleep on the boat and feel safe.
If I read BubbleheadMd's advice out of context I would think he/she was being too forceful. But you should take to heart everything he says. He's trying to help you break through your unrealistic fears.
Here in Upstate New York, it's been cold, and will be for several more months. I am SO anxious to put our boat in the water this spring. I assume my husband will sleep there with me, but he might not-- especially when he's got meetings in the morning to which he must wear a suit.
So when it's cold, one of the things we do here is read, and here are some great books. You can pick them up at your library.
"The Cruising Woman's Advisor," by Diana Jessie
"Changing Course, A Woman's Guide to Choosing the Cruising Life,"6 by Debra Ann Cantrell
"Women at the Helm," by Jeannine Talley
And just get out there sailing with other people-- people you don't even know yet. Put your name on the bulletin boards of some marinas that you find appealing. And just go sailing!
Oh, and have Fun!
