MacGregor 26 vs. ?
I don''t know the McGregor so can''t answer your specifics on the boat, but I do have some advice re. new vs used.
Unless money is no object, I would strongly recommend that you go with a used boat - but find a broker that you can trust and who can advise you well. One of the things you want to determine early on is what type of sailing do you intend to do (racing / day-sailing / extended cruising)and where.
A used boat will generally come with much of the basic equipment (and often a lot more than the basic) that is appropriate for the boat. Of course, the risk of the older boat is that it comes with defects that can''t be spotted by the amateur. This is why you need to have your intended boat surveyed by a reputable surveyer - and don''t fall too deeply in love with the boat before the survey in case emotion overides sense when you get the results - unless you are set on a custom boat, there will generally be another of the same class for sale if you are patient.
