Marine Batteries
The source of DC power is usually one or more marine-grade batteries, normally 12 volts each. They are similar to automobile batteries, except sturdier—and of course more expensive.
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.
Using Prop Walk
You can use prop walk to turn your boat in a tight marina by applying forward and reverse gears at appropriate times, leaving the rudder locked to starboard.
Magnetism
We begin with a phenomenon called magnetism. This phenomenon was known thousands of years before electricity. Magnetism was discovered...
The Types of Sailing Charters

Clothing for Sailing
Dressing appropriately for weather conditions is an important but often overlooked topic. Weather in the marina may be considerably different from weather beyond the marina and conditions can drastically change during your venture.
Sailboat Maneuvering Topics
With practice, wind direction and current direction are not too much of a problem. But what can get you into trouble is extremely high winds. Be prepared to change...
Helpful Hints about Wind
Since the existence of wind is the primary reason we can sail, it is prudent to know all we can about it.
Winged Sail Vector Diagrams
Sail and Winged Sail Wind Force Vector Diagrams. And it's highly relevant right now because of the America's Cup AC45 catamarans using winged sails.
Ferrying Docking Technique
Ferrying is a docking technique whereby you can maneuver your boat in high wind and current easily.
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.
Boat and Equipment Emergencies
The character MacGyver in the TV show of the same name would have made a great sailor. Why? Because he could fix anything and a boat is a concoction of a kajillion gadgets busting to rot...

Mast Head pull heeling versus wind heeling
Takeaways: Standing rigging isn’t the place to economize—it’s a load-management system. Use stretchy docklines for masthead pulls, avoid shock loads, and apply smooth, steady pressure. Snatch loads break rigs.

Motor Sailing
If the wind is light and your time is short you might want to consider motor-sailing—using your auxiliary engine...
Anchoring with multiple anchors
Setting multiple anchors has multiple advantages. It reduces swing, reduces the holding load required by each anchor, and can act as a backup.
Sail Twist Basics
How can the wind direction be different between the top of the mast and the bottom?
