How To Boat Safely By Using Charts, Compasses And Anchors

Using Charts and Topographical Maps

Using Charts and Topographical Maps

Charts are graphic representations depicting water areas including depths, underwater hazards, traffic routes, aids to navigation and adjacent coastal areas. They are intended primarily for the use of mariners to assist in navigation.

Topographical Maps are maps of the land areas depicting natural and artificial features of the land, including elevation contours, shoreline, rocks, land features above water and cultural features. These maps are intended primarily for the use of the general public on the land. The topographical maps are sometimes used where there are no "charts" available but do not depict:

underwater hazards

marine aids to navigation

channels, or

anchorage areas

Using a Compass

It is important to know that using a magnetic compass will help the boater to find directions.

Also, it is important to know that a magnetic compass is influenced by the proximity of metallic and/or electrical devices and could provide false information.

Using Anchors

Anchoring is a safety option to consider in the following conditions:

when severe weather threatens, or

when a pleasure craft is disabled

It is important to know that before anchoring, make sure the inboard end of the anchor line is fastened to a secure point on board and to make sure the outboard end of the anchor line is fastened to the anchor.

To anchor effectively and safely, always remember to fasten a chain between the line and the anchor. With the movement of waves, the boat will tend to rise and fall. When the chain is used, it absorbs the effects of the waves. However, if the anchor is fastened directly to the boat by a rope, the motion of the waves will move the anchor. As a result, the boat will tend to travel because the anchor is traveling. A simple chain between the line and the anchor will avoid this problem.
