Crossing Situations Nav Rules
The Rule 15 (a) when two power-driven vessels are crossing so as to involve risk of collision, the vessel...
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.
Anchoring with Propwalk on a Sailboat
Without proper knowledge of how the boat reacts to the wind and propwalk, anchoring can be a real challenge.
Sailboat Gear and Throttle Controls
Sailboats, and boats in general, use their gears and throttle to control momentum. It’s unlike driving a car in that you have no brake! Instead, you use your forward and reverse gears and throttle to both increase and decrease speed...
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.
Dinghy on a Bareboat Charter
Several things to note about the dinghy on a Bareboat Charter.
The Job of a Sail Trimmer
Sail trimmers in world-class regattas spend years reading and understanding the wind relative to the sails. Sometimes they trim the sheets only a few inches/cm...
Holding a Straight Course in Sailing
Holding a straight course is an imperative skill to master as you learn to sail. As an experienced sailor, nothing is more distracting to a good day out sailing than a novice helmsperson swinging the boat in all directions.
Water and Water Making on Bareboat Charter
Aboard, drinkable water is indeed a limited supply - very limited.
Mediterranean Mooring with an Anchor
Another factor when Mediterranean Mooring with an anchor is that the wind direction determines who is in control...
Anchoring Rode and Scope
To hold a sailboat, the anchor must naturally be attached to the vessel. This is accomplished by using “rode,” which is either all chain or a combination of rope (nylon line) and chain. Learn from this interactive animation.
Lifts and Knocks in Sailing
Lifts and Knocks are technical terms for how the direction of the wind changes, requiring changes in how you respond while sailing...
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...
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.
The Types of Sailing Charters
There are two types of sailing charters; captained and bareboat. The captained charters have a professional captain on board to navigate and operate the vessel, and usually...
Communications while Underway on a Charter
Contact between vessels, or a boat and a land station, is usually carried out using VHF (Very High Frequency) radios.
Available Energy Stored in a Battery
You don’t actually run all of the electron charge out of a battery when it is considered empty.
Magnetism
We begin with a phenomenon called magnetism. This phenomenon was known thousands of years before electricity. Magnetism was discovered...
Springing a sailboat On and In
Coming up to a Tee-head is more the situation where you need to spring on. The need for accuracy in your maneuver is heightened when the space is tight.
Prop Walk Bests You
There is one situation where you are just going to have to suck it up, admit defeat, and work with the forces of nature.
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.
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.
Deploying the Anchor
It is important that the person deploying the anchor and the helmsperson are in agreement about the anchoring plan first. Discuss the placement, the direction, the depth, the desired scope, and the setting plan.
Latitude and Longitude
The latitude and longitude coordinate system is the key navigational concept for sailing. It is the mariner’s coordinate system.
