With respect to Hudson's latest advice, consider this: his advice is correct for someone choosing a boat to go cruising in, and for a long time at that. It seems to me that what you are looking for is first a "home on the water", second a boat to learn to sail locally in and third, something that you can sell on when you are through with this phase of your life.
The choice of keel
shape (fin vs full), rudder
location, means of attaching the keel
and so on don't really enter into your calculations very much. Any of the boats that you have mentioned (at least the ones with which I am familiar) all would pass the basic requirements, and few of them would be a good choice for serious long term cruising
, for that is a different world entirely!.
Obviously, a clapped out Atomic 4 will make it a bit harder to sell the boat on in a few years... but it will also drive down the price
that you will have to pay for it. Whether it will suffice for your learning
sailing should be determined by a competent mechanic
, but the same advice holds for a younger diesel
So, my thoughts are:
Buy a boat that is comfortable for you physically.
Buy a boat that passes a survey
, and negotiate the price
with the knowledge gained by the survey
. This should get you a boat whose price actually reflects its value, and this in turn means that you shouldn't get hurt badly when you sell her onward as you plan to do.
Don't obsess about things like tiller vs wheel
, gas vs diesel
. In the long run they will not be all that big a deal. Remember, there are thousands of folks who have purchased and loved vessels on either side of each of those arguments... it is mostly a personal thing, not do or die significance.
As others have said, finding a boat that is within your budget
, that you can live on as you yourself find adequately comfortable, and that is able to be sailed as is without too much additional work/additions... this is your goal as I see it.
Good luck in your search and your life afloat.
