San Francisco Bar Pilots (SFBP) gave us the opportunity to design three new station boats for their fleet, and we’re proud to report that the contract design is almost complete. To harmonize CARB-compliant equipment, pilot comfort, and a propulsion system with enough horsepower for pilot transfer, Glosten and SFBP opted for a battery-hybrid system—Tier 4 twin propulsion engines outfitted with SCRs and diesel particulate filters will enable the boats to transit to station and keep up with larger ships, while smaller gensets and a PTO/PTI hybrid arrangement will reduce noise, produce zero emissions while running on battery power, and support loitering and battery charging at sea. This design exceeds California’s current emissions requirements, demonstrating the Bar Pilots’ commitment to environmental stewardship and making the vessels more adaptable to future regulations. #navalarchitecture #marineengineering #vesseldesign #CARB
Wow, exciting! We used to fantasize about an electric "trolling mode" for station keeping in good weather. This sounds like a great innovative design.
Looking forward to spotting these!
Looking great! Can’t wait to see them out on the bay
Well done Glosten. You set the bar high!
Great looking boats!
Great job Peter, well done!

7moNice job Glosten fitting the CARB requirements into the tight engine room! Who’s in the running to build her?
