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.
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.
Crossing Situations Nav Rules
The Rule 15 (a) when two power-driven vessels are crossing so as to involve risk of collision, the vessel...
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...
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.
Sailboat Balance
Below is an animation that shows the balance of forces: actually it is technically the balance of a concept called “moments.”
Sailboat Battery Usage
Batteries are a vessel’s major source of power for many essential functions both when in the slip and while sailing.
Returning a sailboat to the Slip
Time flies when you are sailing. But sadly, the moment comes when you must return and put your vessel back in its slip.
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...
The Nautical Chart
Safely maneuvering a vessel while using positions derived from various coastal and near coastal sources is called coastal navigation.
Electronic Communications
Nowadays, gigabytes of data can be sent in a second as a digital signal. It is all a complete Wow!
Names of Thingys in Sailing
There's a lot of terminology in sailing, and to get started with sail trim we recommend beginning with some key sailing "thingy" terms.
Sailboat Diesel Engine
Thanks go to Mr. Rudolf Diesel who years ago in Germany cleverly invented an engine that today bears his name (luckily, they chose to use his last name)—the sailboat diesel engine.
What is an American National Standards EDU-4 Instructor
EDU-4 is the American National Standard that describes what high-quality on-water instruction must look like: clear objectives, structured lessons, appropriate safety and student ratios, objective assessment, and continuous improvement. NauticEd requires its instructors to follow these principles in every training session.
Understanding the Safety Position in Sailing
Learn how the Safety Position — a controlled, depowered close reach — helps sailors pause safely without losing steerage. Ideal for MOB drills, instruction, and more.
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.
Basic Surface Geometry
Below is a brief summary of how locations are commonly expressed on different surfaces.
When Turbulent Flow Happens in Sailing
An airplane stalls and falls out of the sky when the wings stop producing as much lift, similar to when turbulent air flow happens in sailing...
Reefing the Sails
Before heading out, check forecasted wind conditions to see if you might need to reef at some point during the day. If so, make appropriate reefing preparations in the calm marina and ensure your crew knows the procedure.
Propwalk – The Wash Lift effect
The wash-lift effect has been documented heavily by Dave Geer who is one of the worlds leading propeller engineers.
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.
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.
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.
Charter Provisioning
Many charter companies can stock and provision your boat before you arrive. This is a good idea for the basics but there is usually little imagination in the food that is supplied.
