The Spencer 57 accelerates and jumps up to plane in eight seconds, displaying little effort and cutting a clean path into the seas. I was really impressed with the silky smoothness of the boat as well as how quietly it ran, both inside and out, in the cockpit or up on the bridge. At a 1,900 rpm cruise, we made a solid 27.5 to 28 knots, burning a miserly 53 gph – that’s 0.49 nm to the gallon. Back it down to 1,750 rpm, and you still hit 24 knots and burn less than 50 gallons an hour. For a better long-range cruise, back it off to 1,000 rpm. Put the lures out, and at 9.6 knots, you’ll get 0.73 nm per gallon and for an estimated range of more than 850 nm.
