Coast Guard releases request for information for boats to support waterways commerce cutters
A single-design cutter boat is needed to support the 30 new WCCs. The WCC fleet will consist of river buoy, inland construction and inland buoy tenders. The Coast Guard intends to outfit each river buoy tender with two cutter boats and each inland construction tender and inland buoy tender with one cutter boat, totaling up to 56 cutter boats including spare hulls, over approximately 10 years.
The Coast Guard is seeking information about domestic firms’ capabilities and experience in designing and building boats that meet the top-level WCC cutter boat requirements provided in the RFI.
The full RFI is available here. Responses are due at 11 a.m. Eastern time Nov. 1, 2021.
