Re: Full or fin keel?
As it was said by Marty and Ilenart is not so much about the boat but about your skills. As It was said by everybody first you should get a lot of experience before doing a voyage like that. While you get that experience you will sail different kinds of boats, their cost and can have an idea of what kind of boat you prefer or can afford.
I also donít understand why you talk about a 34ft related to budget. First you have to have a budget and then find the boat that fits your budget.
As others have said you should open a thread about your specific problem, related with your budget, best places to learn sailing and so on.
As it was said repeatedly on this thread, seaworthiness has not to do with a boat having a fin or full keel, however if your budget is really small you can be restricted to buying a really old boat and the chances are that one would be a full keel.
Open a thread about that, lots of guys have experience about old inexpensive boats that with some work and money can be made seaworthy again.
