Anchoring on MR Site
In 66 ft, pay out about 350 ft of rode at 5:1 in calm water, or 490 ft at 7:1 when it's blowing. Drop the anchor up-drift of the structure by about the same distance and fall back onto it. Before you drop, kill the engine for 60 seconds and watch your GPS track — that's your real drift, and it beats any forecast.
