Hi Chesapeake, I own a 50’ 2002 Viking Princess FB MY. I agree w Silver Lining that she is a solid boat all around and drives really well. The hull is not cored. I’ve been in really bad ocean conditions and she is solid. Viking Princess and Volvo Penta offer excellent support. I have the upgraded VP 675 hp D-12s that can kiss 31.5 knots. I really love the boat however she may be for sale soon when our daughter leaves for college. She has undergone a $450,000 refit since 2015 on nearly every system.
