Advanced boat handling builds on the fundamental skills introduced in the previous chapter and enables you to deal with more challenging boating situations.


ANCHORING


For a variety of reasons, there will be times when you will anchor your boat. Following are some procedures for setting and retrieving an anchor, as well as information to help you select a suitable anchoring location.


Anchoring Tips E Check the water depth on a chart. If there is tide, make sure there is enough depth at low tide and enough rode (anchor line and chain) at high tide.


E Make sure there are no obstructions above or below the water that your boat could hit when it swings on its anchor.


E Try to anchor in calmer protected waters by choosing a location in the lee (downwind) of land or a breakwater.


E Check your chart to avoid grassy bottoms which are difficult for setting lightweight anchors.


E Do not anchor in channels, high traffic areas, or near underwater cables.


E Take a pass around the intended anchoring area to check for any uncharted hazards.


Boats with deep un- derwater hull shapes sometimes react more to current.

Boats with lots of windage react more to wind direction.

Your boat will rotate on its anchor with wind and current changes, so make sure your swing circle will keep you clear of all obstructions.
