All American Marine Delivers Hybrid Passenger Vessel to Harbor Breeze Cruises

All American Marine (AAM), in partnership with Harbor Breeze Cruises, announced the delivery of a new 108′ x 32.5′ Parallel hybrid passenger vessel, after successful completion of sea trials. El Escudo will now enter deployment in the ports of Los Angeles and Long Beach, California.

Purpose-built to serve harbor tours, whale watch cruises, and special event dining experiences throughout the LA/Long Beach area, the vessel represents a major advancement in low-emissions passenger vessel design. Naval architecture was provided by Nic de Waal of Teknicraft Design, which ensured the vessel exceeded U.S. Environmental Protection Agency Tier 4 and California Air Resources Board (CARB) emissions standards through optimized hull efficiency, full integration of advanced exhaust aftertreatment systems, and a design centered around a parallel hybrid propulsion architecture, enabling zero-emissions operation during low speed harbor operations.

The vessel achieves its operational mission through a highly integrated propulsion system combining Selective Catalytic Reduction (SCR) and Diesel Particulate Filters (DPF) with a parallel hybrid battery propulsion system supplied by ABB Inc. The system features twin 300kW electric traction motors and a 588kW BorgWarner Energy Storage System (ESS), enabling zero-emissions operation during harbor tours and port operations.

This project serves as a demonstration of the latest
