Performance & On-Water Capabilities
Performance depends on installed engine configuration. Typical Harris Grand Mariner 250 boats achieve cruising speeds of 20-26 knots at moderate throttle with wide-open throttle reaching 30-38 knots depending on the engine package. Fuel economy is approximately 4.0-5.0 MPG at cruise speeds.
The 26-foot platform with an 8.5-foot beam provides excellent stability and planted handling even in 2-3 foot chop. The low bridge clearance (5.167 feet) enables navigation under bridges common in river systems. The shallow 1.75-foot draft allows exploration of shallow bays, inlets, and river systems inaccessible to deeper-hulled boats.
Harris’s design philosophy emphasizes comfort, stability, and refined handling characteristics rather than maximum performance. This platform excels for groups seeking leisurely cruising, entertaining, and scenic water exploration.
