Welcome to the community

I'm pretty new to the site, but I can tell you that you'll probably have fantastic luck doing a search for things like 'beginner boat,' or somesuch in the forum threads. These discussions have happened many, many times, and they take months sometimes to get everyone involved. So, rather than waiting around for everyone to chime in, I've found it's pretty helpful to just go cruising the older threads for input and
advice. Still, there are a few things that would help everyone here to provide you with some solid insight.
First, how much experience have you had? Has it been sailing, or
fishing, or
water skiing? All of it counts for something!
Second, how many will be in your crew? If you're married, and your spouse is going to be part of this lifestyle, that impacts a lot of the decisions you'll make along the way in functional, practical ways. We're not necessarily talking hull/sail colors
Third, what's your
budget? Believe it or not, you don't have to spend a fortune to get into
bluewater cruising, but you do have to be pretty serious about outfitting, and this is one of the better places to come in order to find input on that particular subject.
Money does, however, allow for quite a few more creature comforts along the way, and when you're down in that Hawaii-Guam stretch, sometimes creature comforts are foremost on your mind!
There are plenty of other questions, but those are a good start, I think. Others will undoubtedly chime in. But in the meantime, take a look through some of the other threads to get a read on the general attitude regarding this all-important first batch of questions!
Hope you get your dream off the ground sooner, rather than later!
