After navigating the inlet, our test boat turned a 10-knot trolling speed at 1,500 rpm. Wide-open throttle at 2,250 rpm produced 32.5 knots, burning 65 gph with a full load of fuel, water and passengers - quite economical compared to many 45-footers. The most efficient cruising speed was 25 knots at 2,000 rpm, using a cumulative 50 gph. (The 45 was still in the middle of prop experimentation, and the manufacturer expected improvements at midrange and top speeds.)
We trolled the reef off the Florida Keys in a very sloppy 4- to 6-foot beam sea, which translated into a minimal roll. And those who drift-fish will appreciate that whether you put the stern or the bow to the seas at first, you'll end up beam-to in a drift.
