MAVRI

KARL is the result of San Fran- cisco Bay Ferry’s ongoing strategy to operate a public transportation

MV ? eet of the best available passenger

KARL vessel ? eet with the cleanest, low-emission, technology avail- able. KARL and sistership ZALOPHUS meet that goal as the cleanest diesel driven high-speed passenger ferries in operation anywhere. KARL is a high-speed aluminum catamaran built by Mavrik Marine, Inc., and designed by One2Three Naval

Architects. Powered by quad MAN D2862 engines, Reintjes

WVS440 gears, and Hamilton Jet HTX52 waterjets, KARL is capable of an ef? cient 40 knot cruise speed while reducing operating expenses by over 40%. KARL is equipped with an exhaust gas aftertreatment system with Selective Catalytic Re- duction (SCR) and Diesel Particulate Filters (DPF) that inject

Diesel Exhaust Fluid (DEF) ? uid into the exhaust converting exhaust emissions into nitrogen and water. KARL meets Cali- fornia Air Resource Board (CARB) requirements delivering an incredibly clean, low-emission operation while also lowering fuel consumption. Speed, ef? ciency, low operating costs, and clean operations set KARL apart from any other ferries operat- ing today. KARL is an integral part of the ferry system’s daily operations that transports over 2.5 million passengers each year. Because of KARL’s exceptional range, operating ef? cien- cy and speed, KARL is primarily used on SFBF’s longer routes.

The onboard passenger experience also bene? ts from Mavrik’s quality manufacturing, internal system design, and out? t- ting standards with a bright, open cabin accommodating 325 passengers, providing a full galley, USB charging ports, video display terminals, indoor and outdoor seating options with ta- bles, and storage space for 50 bicycles. “The proud craftsmen at Mavrik delivered another exceptional vessel to San Fran- cisco Bay Ferries”, said Mavrik President Bailey Shewchuk, “The four Mavrik Dorado Class vessels in the SFBF ? eet are unquestionably the ? nest quality, most ef? cient, lowest oper- ating cost, and lowest-emission vessels in operation.”
