This research develops a new concept of docking vessel, for the optimization of landing operations. Our idea is separating the functions of transit and landing into two different vessels, where the transporter is the docking vessel of the lander. This idea may lead to an efficient concept, as efficient transportation craft and efficient landing craft have different properties to fulfil the functional requirements. The separation enables the design of each vessel to appropriate cruising speed, range and seakeeping, functional specifications which affect the whole naval architecture of the vessels.
