Hi, I have owned a Mac 25 for a while and it has a way lot more room than the 24 and is a good sailing boat. Once you put the money it to get ready to sail the 24 you could have had a 25. One thing to remember, "There is no cheap boat". You pay now or you pay later. I learned this the hard way.
I bought a 1982 Mac-25 that was in fair shape with good but dirty sails, and a very good motor. Had the sails cleaned and reconditioned, rewired the whole boat, got and Ada rudder, installed all the hardware to run all the controls back to the cockpit.Changed a few new lines, sailed it for a couple of years then moved up to bigger Sailboat last year. Bottom line, it's cheaper to buy one that has been redone. A good Mac-25 like mine can be had for 3 to 4k and the time and money you spend working on her could be spent out on the water. I have the Mac 25 manuals, and can email them if you want. Bob
