BACKGROUND MOST ships have motions such as yaw, pitch, roll, heave, sway and surge caused by waves throughout the Beaufort Scale numbers 0-12. As Beaufort Scale numbers increase in magnitude, these motions also increase in magnitude and can cause catastrophic capsizing, sinking, hull fracture, hull separation, broaching, pitchpoling, swamping, etc. MOST ships, whether they are monohulls, multihulls, displacement hulls, planing hulls or semi displacement hulls, have a bow(s), stern(s), starboard, portside, external deck(s), superstructure(s), keel(s) and are oriented along their horizontal central longitudinal axis between their bow and their stern. They are sensitive in how they orient themselves to waves that may occur in Beaufort Scale numbers 0-12 and this sensitivity increases dangerously as Beaufort Scale numbers increase and wave size increases. SSS is a spinning (rotating) stabilized ship and is dissimilar to most ships due to its rotationally symmetrical wetted surface around its vertical axis, active spinning (rotational) ship stabilization and passive ship shape stabilization. Due to these unique active and passive stabilization features, SSS has extraordinary stability.
SUMMARY SSS is not oriented along a horizontal central longitudinal axis. The wetted surface of all SSS variations must be rotationally symmetrical around their vertical axis. A sphere-shaped SSS is one of many variations which have both a rotationally symmetrical wetted surface and a rotationally symmetrical non-wetted surface around the vertical axis. All SSS variations must have spinning (rotating) ship stabilization. All SSS variations must be able to navigate with their spinning (rotating) ship stabilization either activated or deactivated. Many SSS variations might vary, in their sensitivity to how they orient themselves to waves that occur in Beaufort Scale numbers 0-12, depending on their variations of wetted surfaces and non-wetted surfaces. A sphere-shaped SSS is one variation which is insensitive to how it orients itself to waves. Many SSS variations could have a non-wetted surface which isn’t rotationally symmetrical around its vertical axis combined with a wetted surface which is rotationally symmetrical around the vertical axis. SSS’s loaded displacement tonnage must be balanced around its vertical axis.
