The USCG is looking for sources that are capable of detailed design and fabrication of new wake adapted rudders for the 87 WPB class. The rudders will be wake adapted based on a geometry to the provided GFI by the USCG. The wake adapted rudders will be mirrored pairs of port and starboard as defined by GFI 3D CAD Rhino models. The detailed design is to include the casting process to minimize weight additions relative to the existing rudders (approximately 700 lbs each) while maintaining equal or greater strength. The rudder stock shall be provided by the contractor assembled with the rudders. The external rudder stock geometry and stock finish shall be the same as the existing stock and material of the existing 87 WPBs.
