1Surface Marker Buoy — (standard) = A Surface Marker Buoy, SMB or simply a blob is an inflatable buoy used by SCUBA divers, with a line, to mark the diver s position to their surface, safety boat while the diver is underwater.SMBs are inflated on the surface before… …
2Buoyancy — Buoy an*cy, n.; pl. {Buoyancies}. 1. The property of floating on the surface of a liquid, or in a fluid, as in the atmosphere; specific lightness, which is inversely as the weight compared with that of an equal volume of water. [1913 Webster] 2.… …

9Surface effect ship — A Surface Effect Ship (SES) or Sidewall Hovercraft, is a watercraft or vessel that has both an air cushion, like a hovercraft, and twin hulls, like a catamaran. When the air cushion is in use, a small portion of the twin hulls remain in the water …
10Neutral buoyancy — is a condition in which a physical body s mass equals the mass it displaces in a surrounding medium. This offsets the force of gravity that would otherwise cause the object to sink. An object that has neutral buoyancy will neither sink nor rise.… …
