Designing the Spring Line Maneuver
/by Grant HeadifenLike a work of fine engineering, a spring maneuver requires a design. The key is to plan the maneuver by…
Introduction to Spring Lines
/by Grant HeadifenEssentially, spring lines are just long dock lines.
Multiple Anchors
/by Grant HeadifenThere are occasions when more than one anchor will add safety and comfort. One possibility is to use one or two anchors from the bow, one from the stern, or both.
Anchoring Introduction
/by Grant HeadifenEnsuring that your boat is in the same place you left it is a very important skill. There are also other factors to consider: depth under keel and surrounding area depth, tidal currents, low tide depth, other boats in proximity, wind speed and direction changes, type of bottom, and length of stay. All factors play into your anchoring decisions.
Springing On and In when Docking
/by Grant HeadifenComing into a slip is usually not a problem and does not require a spring because you merely drive the boat using either forward or reverse.
Sound Signals
/by Grant HeadifenSound signals are defined and prescribed in the Navigation Rules for International and Inland Waters. Sound has an advantage over light signals, in that it can be used when vision fails.
Magnetism in Boating
/by Grant HeadifenWe begin understanding electrical energy with a phenomenon called magnetism. This phenomenon was known thousands of years before electricity.
Battery Charging
/by Grant HeadifenLike a water bucket, batteries have a specific storage capacity and must be refilled/recharged when their contents of energy are depleted.
Latitude and Longitude
/by Grant HeadifenThe latitude and longitude coordinate system is the key navigational concept for boating. It is the mariner’s coordinate system.
