The Reefrunner 21 Pilot Vessel by KND is a high-speed, heavy-duty commercial marine platform meticulously engineered with an aluminium planing hull and a matching aluminium wheelhouse/superstructure. Certified under Bureau Veritas (BV) classification standards with HPi CE proof validation, this robust craft is purpose-built to operate safely and effectively in demanding port, harbor, and open-ocean pilotage environments. Structurally, the vessel features an expansive layout measuring 21.00 meters in length overall (LOA) with a wide 5.94-meter beam overall (BOA) and an ultra-shallow 0.58-meter draft. Optimized for intensive, continuous-duty harbor operations, it accommodates a standard 14-passenger complement on a 1-day endurance baseline, supported by heavy-duty logistics capacities that include 350 liters of fresh water and 982 liters of waste water storage.

To provide elite interception velocities and immediate maneuverability when transferring maritime pilots to larger vessels, the Reefrunner 21 relies on a high-output jet drive propulsion arrangement powered by an immense 2,700 hp of recommended installed power ($2 \times 1350\text{ hp}$). Drawing from an extensive 3,432-liter integrated fuel capacity, this powertrain setup propels the vessel to a blistering maximum speed of 48.1 knots and a swift, stable cruising speed of 38.8 knots. Operating at its 38.8-knot cruise velocity, the system logs a fuel burn rate of 386.1 liters per hour, yielding an active tactical and operational transit range of 310 nautical miles at a full-load maximum displacement of 25.34 tons.
