I have looked at both boats. According to most of the listings, both boats weigh 63,800 lbs. The 64 is 66'11" LOA with a beam of 16'3"; 62 is 64'4" LOA with a slightly wider beam of 16'5". According to Sunseeker info, with the same Man V10-1100 engines, the 62 looks to be a more efficient hull - burns less fuel with a better range at cruise RPM. Anyone have first hand knowledge of the ride comparison between the two boats assuming similar engines. Also, how does the 64 run with the Volvo IPS setup?
