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.
Dock Slips Docking Techniques
Wind coming into the dock slip channel and your boat is to be docked stern-to, steer into the slip channel...
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.
The Deck – Getting Familiar with a Charter Boat
Gaining knowledge about the boat, its systems, and its equipment is a great starting point for any sailing adventure.
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.
High Wind and Gust Management in Sailing
Professional sail trimmers deal with high winds and gusts by managing the traveler and mainsheet simultaneously. The fairlead position...
Boat Heading vs Sail Set and Forces on the Sail
The set of your sail depends on your sailing angle to the wind. You're working to maximize the aerodynamic forces on the sail.
The Geography of Confidence
Unlock your boating potential by gaining knowledge. Explore how boating confidence through education expands your horizons.
Unfurling or Raising the Sails
You have motored your vessel from the slip into open water and are now ready to either unfurl or raise the sails, depending on your setup.
Using Spring Lines for Docking
A spring line is just a dockline that is placed strategically from the boat to the dock to help maneuver and turn the boat in place - get it safely into the dock or safely away.
Aids To Navigation (ATONS)
Aids to Navigation include buoys, lights, lighthouses, and markers, among others...
Water and Water Making on Bareboat Charter
Aboard, drinkable water is indeed a limited supply - very limited.
Head-on Nav Rules Situation
The Rule (a) Unless otherwise agreed when two power-driven vessels are meeting on reciprocal or nearly reciprocal...
The Nautical Chart on a Charter
Even though most sailboat charters are within island groups where the next landfall is typically within sight, every boat should be equipped with complete large-scale charts of the area.
Typical Boat and Battery Wiring Schematic
Here is a typical wiring schematic of how your batteries are connected into your boat and charging system.
Luffing and Backwinding Sails
Luffing is when the sail is flapping in the wind. Back winding happens usually right before luffing occurs.
Typical Sailboat Energy Usage
Here we show the devices and how much energy you would typically use on a sailing boat on a sailing vacation each day.
Personal Flotation Devices
The terms “life jacket” and “PFD” are interchangeable, with the latter used in the USA and the former used in most of the rest of the world.
Mast Head and Fractional Rigging
There are two variations on the standing rigging set up: Masthead and Fractional. On masthead rigs, the attachment point for the sidestays (shrouds), forestay, and backstay (if they exist) is at the top of the mast.
Types of PFDs
Types of PDF's Here is a graphical explanation between a lifejacket and a buoyancy vest. PFD Type ratings are being phased out...
Understanding How Airflow Creates Lift
Understanding how Airflow creates lift and the need for smooth airflow when sailing...
Boat Safety Sound Signals
Sound signals are defined and prescribed in the Navigation Rules for International and Inland Waters. Sound has an advantage over light signals, in that it can be used when vision fails.
Basic Surface Geometry
Below is a brief summary of how locations are commonly expressed on different surfaces.
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...
