Michael, According to an old Powerboat Guide I'm looking at, the Gulfstar 48 MY was the first Gulfstar to be built (1981-3) on a planing hull and powered to attain motoryacht speeds up to about 17 kts. Estimates vary on the number of 48 MYs built--the guide cited above says 17 and the Gulfstar Owners Club says 23. Construction techniques included balsa coring in the hull sides to lighten the boat. If I were considering one, I'd want to be sure to have the hull tested for moisture by someone very knowledgeable--a soggy balsa core is NOT something you want to have to deal with! --Milt Baker, Nordhavn 47 Bluewater Michael wrote: I'm considering an early '80s, 48' Gulfstar that has been extensively refurbished including paint, systems and interior. In addition to the normal concerns for a boat of this vintage, what else should I be on the lookout for in terms of potential problems: hull? engines? systems? etc? Any input would be greatly appreciated.
