Sailing and Wind Forces
A sailboat moves in upwind and downwind directions. Downwind is intuitive; it just gets blown downwind. But just how does a sailboat move into the wind?
Sailboat Battery Charging
Like a water bucket, batteries have a specific storage capacity and must be refilled/recharged when their contents of energy are depleted.
Heave To
Heave To in sailing is a way to stop the boat with full sails still up. You might do
Catamaran Maneuvering Mastery
As now learned, Cats can turn inside their own length, they can vector sideways, and using the bulldozer effect you can instantly rotate the Cat to point in any direction, you can do almost anything.
Ferrying Docking Technique
Ferrying is a docking technique whereby you can maneuver your boat in high wind and current easily.
Leaving the Slip with a Sailboat
Wind coming into the slip channel and your boat is stern-to. This is best handled by steering out of the slip and then immediately downwind. Back out of the slip channel and well into the main channel before engaging forward.
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...
Starting the Engine – Getting Familiar with a Charter Boat
Regarding the starting procedure, we’re assuming that since you’re actually commanding a sailboat you pretty much know how to turn the key and all the other safety precautions.
Sail TellTales
"Telltales" attached to the sail in strategic positions to "tell" us what the wind is doing at that exact location.
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.
Shore Power Connection
One of the more common sources of fire on a boat is a loose connection of the shore power to the receptacle plug on the stern of the boat.
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!
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.
Air Flow over the Sails
Similar to steady flight, we've got to keep the air flowing over the sails smoothly...
Vessel Lights and Shapes
Nighttime can be a beautiful time to sail. However, night vision is not the same as day vision and so rules have been established to ensure safety.
Typical Boat and Battery Wiring Schematic
Here is a typical wiring schematic of how your batteries are connected into your boat and charging system.
Head-on Nav Rules Situation
The Rule (a) Unless otherwise agreed when two power-driven vessels are meeting on reciprocal or nearly reciprocal...
Narrow Channels and Traffic Separation Schemes
Rules 9 and 10 deal with narrow channels and traffic separation schemes, and mainly refer to larger commercial traffic...
Aids To Navigation (ATONS)
Aids to Navigation include buoys, lights, lighthouses, and markers, among others...
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...
Starting the Diesel Engine
Prior to starting the diesel engine: Become familiar with how and when a vessel’s transmission gear shift...
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.
Hull and Keel
A sailboat’s hull and keel receive considerable attention from a sailboat designer since they determine the capacity of the vessel, how fast it will go, and the degree of safety and comfort.
Electric Devices and Standards
A word of caution whenever using any home AC appliances on a vessel. Generally, these devices will work fine
