Alternating Current and Direct Current
In your house, your wall outlets deliver alternating current (AC) electricity. The electricity provided to your house and your marina from the national electric grid is AC. Most of the devices...
Understanding the Safety Position in Sailing
Learn how the Safety Position — a controlled, depowered close reach — helps sailors pause safely without losing steerage. Ideal for MOB drills, instruction, and more.
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...
Mediterranean Mooring – Long Line Ashore
The long-line-ashore is a useful Mediterranean mooring method. It is mostly used in the Mediterranean as a customary way of mooring a lot of boats along a shoreline.
Sailing Safety Equipment

Know Your Chart!
Always familiarize yourself with any chart before using it for navigation and plotting of positions; there are significant differences between charts that could lead to mistakes.
Leaving the Dock – End Ties
Wind pushing you away from the dock - This is the simplest scenario. Once you are confident of your plan, release and stow dock lines, then allow the wind to push the boat clear of other obstacles.
Clouds, Fog, Thunderstorms
Clouds can give a relatively easy and quick look at what might be coming in the future. These clouds then are a good indication of possible changing weather in the next few days.
Sailboat Electrical Panels
The sailboat electrical panel, located at the navigation station, normally has two distinct and separately marked sections; one section is devoted to 110-volt or 220-volt AC power and...
Sailboat Diesel Closed Water System
The second sailboat cooling system fluid is called the closed or coolant water system.
Sailboat Diesel Engine Operation
As noted earlier, diesel engines are sturdy and highly reliable, and operating them today is straightforward.
NED Sailing Simulator
Before you play with NED, the sailing simulator, read this first. The graphic below is representative of a real wind meter on...
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.
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.
Momentum on a Sailboat
While sailboats are primarily powered by wind, the use of an engine (technically your sailboat engine is “auxiliary power”) is crucial for certain maneuvers and situations. All of this begins with understanding the momentum of a sailboat!
Weather Predictions
While we have touched on weather concepts in this Module, no one can expect you to be a meteorologist (unless you are one) and do a good enough job at predicting the weather with enough quality to guarantee your safety.

Safe Speed Nav Rule
The Rule Every vessel shall at all times proceed at a safe speed so that she can...
Sailboat Running Rigging
A sailboat’s running rigging consists of those items controlling the sails and helping the sails to capture the wind’s energy.
Sailing Wind Velocity & Direction
The faster the boat sails into the wind, the more the apparent wind speed increases and the more it feels like it is coming from the front of the boat. They say "The apparent wind is forward of the true wind". This means the apparent wind feels like it comes from a more forward direction than the true wind.
Sailboat Diesel Engine
Thanks go to Mr. Rudolf Diesel who years ago in Germany cleverly invented an engine that today bears his name (luckily, they chose to use his last name)—the sailboat diesel engine.
