Description: Vertical plane response of submersible vehicles in the proximity of a free surface in deep water is evaluated      using a potential flow, strip theory solver. Two criteria, that are periscope submergence, and sail broaching are      used to quantify the response. These criteria combined with the vehicle's response amplitude operators in      regular sinusoidal waves along with a statistical description of the seaway lead to an assessment of an overall      operability index for the vehicle. This thesis presents a systematic parametric study of the effects of body      geometry on near surface response. Two cases, namely limited diameter and limited length are considered. The      total volume of the vehicle is kept constant, and certain shape factors are changed, while either the overall      diameter or the overall length remains the same. The operability index is calculated for each case within a given      range for sea states and sea directions and for various shape factors, vehicle speeds and operating depths. The      results indicate that certain changes of shape factors can improve vehicle operations in various depth and speed      combinations.
