Explanation:
17.5/0.07=250
It can be dangerous to extract a snagged anchor in deep water, and may also cause trouble in heavy seas, putting your boat at risk. If it happens and you are unable to extract the anchor from water, then cut the line. ... This means you will use three times as much anchor line as the depth.
There is no difference between the anchor hanging in the water and sitting in the boat, since the system boat + anchor weighs the same either way.) The water level depends on how heavy the anchor is. If you make the anchor heavier, it pulls the boat down further, pushing the water out of the way.
