Spirit's bow and stern thrusters make maneuvering her 80 feet effortless. The skipper simply moved her sideways from the dock, engaged forward on the engine controls and slowly headed into the channel. Spirit cruises at 1900 rpm, which is 10 knots through the water, a tick slower than her 11-knot theoretical hull speed. She's content at this speed and should be able to hold it for days in the smooth seas that accompany calm winds. She carries about 1,000 gallons of fuel, enough to motor out of nearly any calm. When we pushed her to the 2300 rpm maximum, 11 knots, she started to dig a hole in the water, indicating she'll spend most her life at or below hull speed.
