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...
The Autopilot on a Charter
The autopilot is a great tool for those long hauls and it’s probably better at holding a straight line than most of us.
Crew Overboard
Crew ("Man") Overboard (MOB) is fortunately relatively rare, but chances are that in your sailing career it will happen.
Mooring a Sailboat
Mooring a vessel means attaching it to a float that is firmly and permanently anchored to the sea bottom.
Spinning Propeller
As you sail along, the water flowing over your propeller will cause it to spin. Some sailboats are fitted with a special alternator that will create electricity...
Anchoring
Anchoring is not simply throwing a “hook” and letting out a line. However, after watching some sailors, this seems to be their theory. Successful anchoring requires a plan considering all the factors.
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.
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.
Risk of Collision when Sailing
The Rule of Risk of Collision is that every vessel shall use all available means appropriate to the prevailing circumstances...
Rigging
At boat shows, we see folks huddled down in the vessel’s salon oohing and aahing at the leather cushions to sit on, and at the electronic gadgets for navigation and entertainment.
Global Positioning System
GPS stands for global positioning system. It uses a network of satellites in orbit. Although the GPS is used as a navigation device, it is also a form of communication to the vessel.
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.
Sailing Heave To
When you have successfully hove-to (heaved-to), your sailboat will be in a stable situation with the mainsail and headsail still up. Your forward speed will be minimal and...
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.
Securing Your Sailboat
It is convenient to have dock lines that are pre-set to the right length with loops on the end and are permanently mounted onto the marina cleats. Now, when you return to the dock you simply slip the loops over your vessel cleats.
Crew Safety Briefing
You can avoid many emergencies by conducting a proper safety briefing before leaving the dock.
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.
Generators on a Charter Boat
Some charter boats have generators. These are small diesel engines that convert fossil fuel to DC electricity that is stored in the battery banks and AC electricity that is used to run the air conditioning, microwave, and AC outlet plugs around the boat.
Sailboat Wind Power Generators
Wind-power generators are typically installed only on ocean-crossing vessels, where the vessel is away from the marina for extended periods of time and where there is a need for conserving onboard fuel.
Sailboat Diesel Water Systems
Diesel engines run hot because of high compression and therefore need to be cooled. Fortunately, ample cooling is readily available from the water the vessel is sailing in.
Holding a Constant Heading while Adjusting the Sails
We're heading to a specific point on land or a compass heading. Thus we need to keep the sails flying effectively...
Some Navigation Rules Terminology
Understanding Navigation Rules begins with learning some basic Navigation Rules terminology...
Standing Rigging
To keep the mast from toppling over, an array of rods, cables, ropes (lines), and wires are attached at various spots on the mast and run down to the bow, stern, and sides of the vessel.
Types of Anchors
Anchor design has been the focus of much research over thousands of years, and as a result, there are
