What are factors affects Secure Anchoring?

3. Tides and currents

You need to know the tidal range to compute adequate scope. Rising tides could break out an anchor with inadequate scope. Lower than- normal tides could increase scope to the point .In areas with shift ing currents, set two anchors. Always be aware of changes in direction and strength of wind, current, waves, and swell when at anchor.

4. Swinging room

Take the time to circle the anchorage and see if ships  are using one or two anchors. In areas like the Bahamas where currents shift 180 degrees, ships anchor with two anchors. Make sure when your ship swings to a single anchor that it clears other ships and shoals.
