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.
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.
Typically used to assist in docking and undocking a boat, with its hook used to pull a boat towards a dock and the blunt end to push it away from a dock, as well as to reach into the water to help people catch buoys or other floating objects or to reach people in the water. boat keeper

Marines sometimes are thought by seamen to be rather gullible, hence the phrase "tell it to the marines", meaning that one does not believe what is being said. 2. An alternative term for a navy, uncommon in English but common in other languages. 3. Of or pertaining to the sea (e.g. marine biology, marine insurance, marine salvage). 4.
Hydrostatic pressure due to depth in the water column. Hydrostatic pressure is linear with depth and increases at approximately 1 bar for every ten metres of depth. [1]: Ch 1.3 Temperature of the water and the air above it. Sea surface temperature can vary from a minimum of −2 °C (28 °F) to a maximum of about 32 °C (90 °F). Higher surface ...
A half tide dock is a partially tidal dock. Typically the dock is entered at high tide. Typically the dock is entered at high tide. As the tide ebbs a sill or weir prevents the level dropping below a certain point, meaning that the ships in the dock remain afloat, although they still rise and fall with the tides above this.
The squat effect is the hydrodynamic phenomenon by which a vessel moving through shallow water creates an area of reduced pressure that causes the ship to increase its draft (alternatively decrease the underkeel clearance of the vessel in marine terms) and thereby be closer to the seabed than would otherwise be expected.
