What is charted depth
mobile feature varies in position and height and is periodically dredged to maintain a charted depth of 1.5 metres. The width of the dredged channel across the overhanging obstruction, or depth of both heights of tides and water depths expressed as reference plane, and heights of tide and charted depths are. 4 May 2014 The depth of water available at any time is obtained by adding algebraically the height of the tide at the time in question to the charted depth. 5 May 2011 MHWS – MLWS = Mean Spring Range MHWN – MLWN = Mean Neap Range. Depth = Charted Depth + Height of Tide OR Height of Tide 25 Jul 2017 Underestimation of charted depth is expected for the case that LAT falls below CD. Such a risk magnifies with decreasing depths, as well as the Pacific Ocean where offshore water depths are well over 3,000 feet in depth. comparing the vessels draft to the charted depths and considering the age of the

observed depth measured by an echo sounder, the notes should include the date continue to be recorded until general agreement with surrounding charted.
Tread depth is a vertical measurement between the top of the tread rubber to the bottom of the tire's deepest grooves. In the United States, tread depth is measured in 32nds of an inch. Because it is difficult to accurately measure tread depth with a ruler, tread depth is best measured with a tire tread depth gauge.
The depths may be in either feet or fathoms (the chart will indicate which). A fathom is a nautical unit of measurement and is equal to six feet. On a chart, water depths may be connected with a line known as a depth contour, similar to the topographic lines or surface features that you see on a map.

We can use the Tidal Levels information on the chart to quickly asses the Depth of Water (Depth of Water = Charted Depth + Height of Tide) Example: Fig 5.13 - We want to make passage The depth on the right indicates a minimum depth at that point of 5.6m. These numbers or CHARTED DEPTHS are not the only depth indication. There are also contour lines on the seabed. These join places of equal depth below chart datum. The depth is written within the contour line.
