Certainly that will take us from Alaska to Mexico and the Caribbean, with the possibility of the South Sea Islands. We are looking for a boat that will be a good liveaboard, coastal cruiser and be able to tackle blue water if we choose.
Unfortunately you are describing a boat that does everything. It's almost impossible to do everything well. being a liveaboard has it's own problems. It means it has to hold everything you own and that tends to fill the boat totally. being a blue water boat means it has to endure harder stress. Doing both of those means you need a very stout boat.
Taking a trip to YachtWorld.Com would help you see what is out there. I think you need to think in terms of total costs and that is a lot harder than just a purchase
price. Over time what you paid for the boat is not as important as what you will pay over time. It's all your money
. Larger boats significantly adds to all the rest of the costs and the costs of maintaining. A fully loaded Gulfstar
from the 1970's really is not going to be up for a Pacific crossing assuming you were ready as well. 1970's boats are a lot cheaper but a while the hull
may be fine (it it ever was) most everything attached is quite old and replacement costs quickly eat all your savings and more. Rebuilding a boat from the inside out is very expensive. Something a little newer that has had work already done is going to save you more up front costs.
We get a lot of "which boat" requests and they really are quite difficult to answer. It takes some time for you to understand how the money parts
work and it takes more time to gain enough sailing skill to be able to understand the boat characteristics required for the many things you might do. Since you might not actually do everything it matters a great deal what you actually would do. It becomes a process you grow into rather than just an answer.
You can find a lot of the discussions here but they won't be about you. They may give you more to think about and that may expand the depth
of your conversation as you grow along. I like to say there are no wrong boats just the wrong people in them. People seem to fear picking the wrong boat most of all. I don't really know why that is but the process is more about you than it is the boat. It's supposed to be that way. You are far more important than the boat. Taking that into consideration first makes sure the most important part is not ignored.
