Mooring a Sailboat
Mooring a vessel means attaching it to a float that is firmly and permanently anchored to the sea bottom.
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.
Docking onto End Ties
Wind blowing you off the dock end ties, plan a fairly steep approach so that you are facing more into the wind.
Dual Rudder Monohulls
When a monohull sailboat has dual rudders, the boat will act with different characteristics than with a single rudder. Thus, the point of this module is to help you maneuver a dual-rudder monohull sailboat.
Overtaking Vessels
When overtaking another vessel, we quote the rules exactly because they are incredibly clear...
Basic Sail Telltale Control
Controlling the Telltales by Trimming the Sail. The concept here is actually pretty simple. The golden rule is, when...
Lights on ATONS
Lights are installed on some ATONS. The lights are usually alternating on and off on some consistent interval to distinguish one ATON from another.
Air Flow over the Sails
Similar to steady flight, we've got to keep the air flowing over the sails smoothly...
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.
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.
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.
Getting the General Feel of Maneuvering a Catamaran
Some have compared maneuvering a catamaran with driving a bulldozer. Well . . . perhaps!
Some Navigation Rules Terminology
Understanding Navigation Rules begins with learning some basic Navigation Rules terminology...
More Basic Sail Twist
The wind at the top of the mast has more heeling leverage on the boat than the wind lower...
Docking Maneuvers with Dual Rudders
With Dual Rudders there is no ability to spring the boat onto or off the dock! You have no water velocity over the rudders from either boat velocity or propwash.
True Wind vs. Apparent Wind
Learn the basic difference between True Wind and Apparent Wind...
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...
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.
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.
Towing
The following diagram shows how you can tow another vessel. Form a “bridle” from the rear cleats...
Maintaining a Lookout
The Rule Every vessel shall at all times maintain a proper look-out by sight and hearing as...
Sailing Safety Introduction
Emergencies at sea extend from simple and almost funny episodes to major challenges that are extremely serious.
