Reading Reddit today, I came across this great video…
About two thirds into his brilliant video, Richard Macfarlane points out something that is seldom considered: shallow water requires more scope than deeper water does. He gives us this graph:
I thought I’d print this out and laminate it to use when anchoring, but then he went a step further and gave us a simple formula to approximate the above graph:
I mentioned this concept, though not as concisely, in a post about changing our anchor chain. In that post there was this link to a great article from Rocna about depth and catenary.
From now on, for me, it’s going to be “double the depth plus 15 meters” and “add another ten meters if it’s windy or over a questionable bottom.
