The 45EX offers a good deal of amenities in a spacious midsize express. Her stylish looks, plush accommodations and noteworthy performance make her a candidate for the short list of anyone looking for an express capable of reaching the offshore fishing grounds, or a great liveaboard for weekending.Courtesy Hatteras

You get to the engine room through the helm-deck floor hatch. The C18A Caterpillars are nicely nested in the space. Things are a bit tight, but for a 45-footer, she offers good access to raw-water pumps, belts, filters and the like. The generator sits back under the mezzanine deck, where it might be tough to work on, but the basics, such as checking oil, should be easy. The electrical, plumbing and equipment layout and execution is clean and tight.Courtesy Hatteras

The 45 seemed quite nimble and maneuvered well, with her beam providing good separation of her props and rudders. She gained speed quickly, making 20.2 knots at 1,400 rpm, burning a mere 25 gph. Advancing the throttles to 1,600 rpm, she burned 32 gph at 26.9 knots, quite a gain in power and speed for not much more fuel per hour. A fast cruise of 2,000 rpm produces 35.9 knots at 43 gph, and on the pins, the 45EX turned 2,330, zipping along at an honest 40.5 knots while burning 60 gph. — Adapted from Boat Review: Hatteras 45 Express by Capt.
