Sailboat Design
Surely, the first sailboat was invented by a five-year-old child with a block of wood. He or she stuck a twig through a piece of animal skin and then down into a knothole in the wood.
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...
Sailboat Balance
Below is an animation that shows the balance of forces: actually it is technically the balance of a concept called “moments.”
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.
Plumbing and Tankage – Getting Familiar with a Charter Boat
A diaphragm pump below directs flow from the water tank(s) to various faucets throughout the boat. You'll always begin a charter with full water tanks but understand that water conservation is still required.
Key Sailboat Instruments
Sailboat Instrumentation can be very sophisticated and intelligent. Most electronic displays provide a wide range of menus of useful information...
Terms Port – Starboard – Forward – Aft
In discussing sail trim, certain terminologies must be understood and so we are presenting a few basics to get you started
Maintaining a Lookout
The Rule Every vessel shall at all times maintain a proper look-out by sight and hearing as...
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!
Sailboat Generator or Large Battery Bank?
Dedicated electric generators on board sailboats are usually only reserved for large sailboats because of their weight and size. Unless there is a desire for large amounts of electricity...
Docking Force Alignment and Moment Balance
When you are docking, if your boat pulls on a line attached to the dock, the line pulls back on your boat. If the forces are aligned, then nothing really happens.
Basic Surface Geometry
Below is a brief summary of how locations are commonly expressed on different surfaces.
Dock Line Release
Have a dock line untying plan based on the wind and the current direction and then communicate this to the crew. Depending on which is stronger...
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.
DC Electrical System on a Charter Boat
Batteries power the 12 Volt DC “house” electrical system. There may be one or several batteries linked together to supply power...
Sailboat Inverters
Sailboat Inverters are devices used to convert 12-volt DC battery electricity to AC 110-volt or 220-volt electricity. Special electronics in
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.
Sailing Safety Equipment
There is a plethora of equipment specially designed for a variety of emergencies at sea. Some are inexpensive...
True Wind vs. Apparent Wind
Learn the basic difference between True Wind and Apparent Wind...
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.
More Basic Sail Twist
The wind at the top of the mast has more heeling leverage on the boat than the wind lower...
Some Navigation Rules Terminology
Understanding Navigation Rules begins with learning some basic Navigation Rules terminology...
Anchoring Courtesy
After safely and securely anchoring your vessel, there are certain factors to contend with - most are common sense.
Tacking and Gybing Maneuvers
Tacking when you want to sail in a direction to exactly where the wind is coming from— guess what—you can’t! The best we can do is to follow a zig-zag course by sailing at about 30 to 40 degrees off the wind...
