The boats are among the first EPA Tier 4 pilot boats in the U.S. and the first using a three-engine MAN configuration. Kern said the group initially debated the setup, “we figured out that running those three engines, but not running them at full power, has given us about four knots faster than our old boat, but burning less fuel.”
The contract required 30 knots at roughly 80% load. With an inverted deep-V hull designed by ECS Marine, the San Jacinto exceeds that mark, cruising at 32.5 knots at 1,950 rpm with a 37.5-knot top speed. Fuel burn is 43 gph per engine, with 2,200 gals. fuel capacity.
The main engines are fitted with water-cooled exhaust systems and Soundown-built SCR units mounted overhead. Three 145-gal. stainless steel DEF tanks support the emissions system.
A fixed CO₂ system with dual 100-lb. bottles, auto engine shutdown, and vent closures was supplied by Total Safety and installed by Burner Fire Control. Read full article here
