We’ve previously outlined the advantages of big anchors (shorter scope, less swinging room, security, quicker setting). But we neglected one huge factor, reducing scope reduces the risk of fouling.<\/p>\n
Here is an example. Assume you are anchored in forty feet (12m) of water including an allowance for the height of the bow roller off the water.<\/p>\n
<\/p>\n
In light airs, with five to one scope, you would veer 200 feet (60m) of chain. Most of that, say 150 feet (45m) is on the bottom. The area swept by the chain on the bottom is equal to the radius squared times 3.1416, or 17,671 square feet (1673 square meters).<\/p>\n
Now lets switch to our big anchor and reduce scope to 2.5 to one. The chain lying on the bottom is reduced to 75 feet (22m) and the area swept drops to 4418 square feet (418 square meters). The huge reduction in swept area is a function of the circle radius being squared in the area formula.<\/p>\n
The chain on the bigger anchor and shorter scope sweeps 1\/4 the area of the conventional set up. So, whatever the risks are from boulders, coral heads, wrecks, etc. they are a lot less with the bigger hook.<\/p>\n
On Wind Horse<\/em>, our normal practice is to set on a longer scope and then shorten down, even when there is plenty of swinging room, to reduce the risk of fouling.<\/p>\n","protected":false},"excerpt":{"rendered":" We’ve previously outlined the advantages of big anchors (shorter scope, less swinging room, security, quicker setting).
