Inside the dock, the depth of water beneath the sill's level depends only on the depth to which the dock was excavated, although this obviously increases construction costs. The importance of the sill, and the tide's height above it, is reflected by these dock sills becoming an important local datum level and for tide tables being calculated ...
Dock jumping, also known as dock diving, is a dog sport in which dogs compete in jumping for distance or height from a dock into a body of water. There are dock jumping events in the United States and other countries such as United Kingdom, [ 1 ] Australia, [ 2 ] Germany, [ 3 ] and Austria.
UKC = Charted Depth − Draft-/+ Height of Tide. Ship masters and deck officers can obtain the depth of water from Electronic navigational charts. [5] More dynamic or advanced calculations include safety margins for manoeuvring effects and squat. [7] Computer systems and software can be used to manage and calculate UKC for ships and ports.
Her top deck is about 60 feet (18 m) below the water's surface. The vessel's hull, which is a labyrinth inside, is as much as 135 feet (41 m) under water, and silt can get kicked up and reduce visibility inside to almost zero, which can cause disorientation. [8] The depth of the wreck requires that divers have an advanced certification. [7]

A person jumping off a cliff in Arizona. Cliff diving is the leaping off a cliff edge, usually into a body of water, as a form of sport. It may be done as part of the sport of coastal exploration [1] or as a standalone activity. Particular variations on cliff jumping may specify the angle of entry into the water or the inclusion or exclusion of ...
In 1715 the first commercial wet dock, Liverpool's Old Dock, opened. [2] Early docks were of simple construction: a single lock gate isolating them from the tidal water. The gates were opened during the last hour [or two] of the rising tide, giving a short window of opportunity to let ships in on the rise and releasing outgoing ships while the tide was on the t
A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". [1] That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed.
