25' Response Boat Small (RBS)
Station Bayfield operates one 25' Response Boat Small (RBS), hull number 25405.
Developed in a direct response to the need for additional Homeland Security assets in the wake of the September
11th terrorist attacks, the Defender Class boats were procured under an emergency acquisition authority. With a
contract for up to 700 standard response boats, the Defender Class acquisition is one of the largest boat buys
of its type in the world.
The Defender Class boats currently in operation are assigned to the Coast Guards Maritime Safety and Security Teams
(MSST), Maritime Security Response Team (MSRT), Marine Safety Units (MSU), and Boat Stations throughout the Coast
Guard. With an overall length of 25 feet, twin 225 horsepower outboard engines, unique turning radius, and gun mounts
boat forward and aft, the Defender Class boats are exceptional waterborne assets for conducting fast and high speed
maneuvering tactics in a small deployable package. This is evidenced in the fact that several Defender Class boats
are already in operation by other Homeland Security Department agencies as well as foreign military services for
their homeland security missions.
45' Response Boat Medium (RBM)
Station Bayfield operates one 45' Response Boat Medium, hull number 45653.
The new 45-foot Response Boat-Medium (RB-M) boasts an improved design, new ergonomics, and enhanced safety features,
making boat crews more effective in performing their multiple missions. The RB-M is part of the Coast Guard’s plan to
standardize and revitalize its shore-based boat fleet. The RB-M replaces the aging 41-foot and other non-standard
utility boats. The RB-M project has delivered a new boat with significantly increased speed and performance, improving
response time and agility for missions. The boats’ also are designed with human factors systems engineering concepts in
mind, decreasing crew fatigue on extended patrols.
