The FLO/FLO is a concept ship that could support the MPF(F) squadron with responsibilities such as skin to skin interfaces, LCAC and EFV deployment and recovery, and LCU interface. The goal of this study was to test the FLO/FLO concept ship 1:60 scale model in the NSWCCD 140 foot basin at two specific loading conditions, LCAC operations and EFV recovery, and irregular head seas to determine the amount of deck wash, the wake, and seakeeping characteristics with two transom configurations. Testing included observations made with and without a stern extension at four velocities in Sea States 2 and 4. In the EFV ballasting condition, the model had increased weight, drafts, and trim angles to create a beach like transom to efficiently recover the vehicles. Less ballast is required for LCAC operations and the model was at its lightest. The stern extension was the largest factor in the model performance. The model fitted with a stern extension had decreased water entry lengths and better seakeeping results. Results of the testing will help to determine future stern configurations and modifications necessary to increase the overall capabilities of this concept ship.
