Novice Sailors buying boat
Just a couple of additional points to consider...
You may not know exactly what type of characteristics you want in a boat until you''ve had time to sail on a few. So, generally it''s recommended that you sail on OPB (other people''s boats) for a while before buying... then, you can make a more informed choice.
However, finding a boat that you''re absolutely in love with is not always an easy thing to do, so, if you''ve managed that, then what the heck!
But, as others have suggested, perhaps take some sailing lessons on smaller boats to develop the necessary skill and confidence to enjoy your own boat.
