Using Spring Lines for Docking
A spring line is just a dockline that is placed strategically from the boat to the dock to help maneuver and turn the boat in place - get it safely into the dock or safely away.
Sailboat Fire Extinguishers and Requirements
Fire Extinguishers Fire Extinguishers are given a letter rating that matches the type of fire they will be battling.
Understanding Energy and Power
Energy: The concept of energy is likened to water for the easiest understanding. A bucket of water holds a specific amount of water which is measured in a quantity of gallons or liters. It is finite; when it is all drained out, it is gone. To gain more, it must be replaced from a source.
Propeller Entanglement
If there is a sudden slowing or stopping of the engine while motoring it is possible that you have picked up some floating line, hopefully not from your vessel.
Chart Symbols
Studying a harbor layout does very little good without understanding the symbols and what they signify. It pays to
Luffing and Backwinding Sails
Luffing is when the sail is flapping in the wind. Back winding happens usually right before luffing occurs.
Weather Warnings
Weather services will also provide weather warnings, such as small craft or gale warnings for a certain area, as well as fog predictions.
Generators on a Charter Boat
Some charter boats have generators. These are small diesel engines that convert fossil fuel to DC electricity that is stored in the battery banks and AC electricity that is used to run the air conditioning, microwave, and AC outlet plugs around the boat.
Air Conditioning on a Sailboat
Air conditioning is an enormous energy drain.
Sails
Sails are sophisticated objects. It is not only the materials they are made from that are important, but also, the way they are cut and sewn.
The Nautical Chart
Safely maneuvering a vessel while using positions derived from various coastal and near coastal sources is called coastal navigation.
Rigging
At boat shows, we see folks huddled down in the vessel’s salon oohing and aahing at the leather cushions to sit on, and at the electronic gadgets for navigation and entertainment.
Mediterranean Mooring with an Anchor

Leaving the Slip with a Sailboat
Wind coming into the slip channel and your boat is stern-to. This is best handled by steering out of the slip and then immediately downwind. Back out of the slip channel and well into the main channel before engaging forward.
Electronic Navigation
We are well into the 21st century. Chances are that within 30 feet (10 meters) of you right now there are 2-3 GPS-enabled potentially lifesaving devices...
Mast Head and Fractional Rigging
There are two variations on the standing rigging set up: Masthead and Fractional. On masthead rigs, the attachment point for the sidestays (shrouds), forestay, and backstay (if they exist) is at the top of the mast.
Marine Radio Licensing
To operate a marine radio lawfully, you must comply with the laws of the country in which you are operating the radio.
Anchoring Courtesy
After safely and securely anchoring your vessel, there are certain factors to contend with - most are common sense.
Sailboat Solar Power
Solar panels produce DC power and are used to charge the batteries. A relatively small solar panel such as 1 square foot (0.1 m2) can produce about 1½ amps at...
