I am looking to move up to a convertable Sportfish from a 40 Cabo express. There are 2 yachts I am interested in. One is a 2005 Hatteras 54 with 1550 HP Cats that has aprox 1500 hours. the other is a 2006 56 viking with 1360 CR MANS that have approx 1250 hours. The eqipment on the boats are basically the same. There is a price difference of about 200K. with the viking being more expensive. First does anyone have any experience with either boat and second is the Viking worth the price difference. Are the C30 CATS a better deal than the MANS. I currently have MANS in my Cabo and have been very reliable.
