the plimsole line or mark was named in the 19th century . the line shows if the vessel or boat is over it is out of the water then the vessel or boat is not over but if it is in the water then the vessel or boat is over the weight and some thing must be taken off ! as it is legel to be over the weight that boat or vessel should be.
Assuming you are on a boat and you are using a standard sized anchor, then if the water is 20 feet deep you'd use 20 feet of line.
A boat weighs the same as the water it displaces i.e. the volume of the boat that sits below the water.
To set up the equation for finding the current of a river, you typically consider the speed of a boat relative to the water and the speed of the boat relative to the ground. Let ( v_b ) be the speed of the boat in still water, ( v_r ) be the speed of the river current, and ( v_g ) be the speed of the boat relative to the ground. The equation can be expressed as ( v_g = v_b + v_r ) when the boat is moving downstream and ( v_g = v_b - v_r ) when moving upstream. By measuring the ground speed in both directions, you can solve for ( v_r ).
To kedge or kedging is the act of setting an anchor by dinghy or by wading out away from a grounded boat and heaving towards the anchor until the boat is pulled into deep enough water to be able to float freely!This could be repeated a number of times if necessary to free the boat.
One place to avoid anchoring a boat would be to not anchor it near a launching ramp.
