Self-Propelled Boat Trailer For the (USCG) Ready Boat Medium (RB-M)

Specification

1. SCOPE

1.1. This specification is for a self-propelled trailer to be used for hauling, transporting and launching the (USCG) Ready Boat Medium (RB-M).

1.2. The U.S. Coast Guard (USCG) Sector in Guam operates and maintains two 45 foot RB-Ms. In order to facilitate maintenance, repair, and storm avoidance a self-propelled trailer is required that can be used to haul an RB-M using a boat ramp located at the Coast Guard facility in Guam, transport the RB-M to and from a maintenance facility on the same property, and then launch the RB-M using the same ramp.

1.3. The lift will be designed such that once transported to the maintenance facility, the RB-M can be supported separately from the trailer and the trailer removed.

2. APPLICABLE DOCUMENTS

2.1. The following documents are referenced in this specification:
