    Well bought it . and very happy it is a Great boat spent a lot on upgrades . but it was worth it a 55 with 4 state rooms three full heads she handles well and very economical at 10 knots running the gen set and two 8 92 tts each 600 hp 16 gal per hour but if I need to go fast she's good for 20 plus knots I will spend the next year doing the little things the last owner never did but all and all I am very happy .

    Congrats on your purchase. My neighbor has one and what a fantastic vessel it is. How do you like those heavy doors?

    Gary C. There's a wire chase from the base of the radar arch on the port side that heads toward the helm.

    16 GPH at 10kts isn't very economical Cut the speed down to 9.25 / 9.5, likely to be hull speed for your boat and you will bring it down to 10 GPH

    Once you reach hull speed, commonly calculated as teh sq root of waterline length X 1.3, fuel burn jumps up exponentially

    My 53 burns 9 GPH at 9kts.

    I run a 70 footer with electronic engiens and flow meters. It's a real eye opener. 10 kts (hull speed for that boat) and we burn 18pgh. Bump it up a knot and it jumps to 30gph! 10% more speed, 50% more fuel. Bring it down to 9kts, and flow drops to 10gph.

    And Dean my hull is number 2 . and it has a complete walk around . and it's a wide walkway. the wide body's built later by Viking loose this . but it still has a 17.6 beam all window frames sliding doors at stern and air vents for engines are all stainless steel not aluminum a big plus for a 29 year old boat
