Planning to use springlines when docking
Like a work of fine engineering, a spring maneuver requires a design. The key is to plan the maneuver by considering the wind, current, and other obstacles, then design the placement and directions of the forces and moments.
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...
Mediterranean Mooring – Long Line Ashore
The long-line-ashore is a useful Mediterranean mooring method. It is mostly used in the Mediterranean as a customary way of mooring a lot of boats along a shoreline.
Rudder Force with Spring Lines
The rudder can be a big help because it can change the direction of the thrust force.
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.
Boat and Equipment Emergencies
The character MacGyver in the TV show of the same name would have made a great sailor. Why? Because he could fix anything and a boat is a concoction of a kajillion gadgets busting to rot...
Mooring on a Charter
Most developed chartering locations throughout the world have established zones in which mooring balls have been permanently implanted.
Understanding Weather Systems
Weather is a highly complex natural phenomenon. Globally, it is all connected and operates on a multitude of physical laws.
Take Note When the Boat Heels Over or Stands Up
At a sailing group meeting, someone mentioned they were having trouble determining if the boat was pinching or not.
Key Sailboat Instruments
Sailboat Instrumentation can be very sophisticated and intelligent. Most electronic displays provide a wide range of menus of useful information...
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.
Weighing Anchor
“Weighing the anchor” simply means raising it. If raising the anchor is to be done by hand...
Ferrying Docking Technique
Ferrying is a docking technique whereby you can maneuver your boat in high wind and current easily.
Head-on Nav Rules Situation
The Rule (a) Unless otherwise agreed when two power-driven vessels are meeting on reciprocal or nearly reciprocal...
Sailboat Diesel Engine Fluids
Diesel engines make use of a variety of fluids, including raw and coolant water, diesel fuel, and lubricating oil. A problem in the flow of any one of these fluids can cause problems...
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.
Responsibility between Vessels Nav Rules
Every vessel has a definition of being one and only one of the below at all times. And each vessel has the ability to morph from one to the other.
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.
Seasickness on a Bareboat Charter
Here is some education about sea sickness that can help you and your crew overcome it.
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.
Sailboat Engine and House Systems
Perhaps the most important use of DC power on a vessel is for starting the engine. Considerable power is needed for this task and if the engine does not start immediately...
Sailboat Battery Usage
Batteries are a vessel’s major source of power for many essential functions both when in the slip and while sailing.
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.
Sailboat Balance
Below is an animation that shows the balance of forces: actually it is technically the balance of a concept called “moments.”
