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.
Waves, Swells, and Depth
Since waves are primarily the result of surface wind action, they can be accurately predicted. Waves have troughs and crests.
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.
Electronic Communications
Nowadays, gigabytes of data can be sent in a second as a digital signal. It is all a complete Wow!
Diesel Fuel
The search, discovery, refinement and resource control of fuel has a rich and very sordid history. But just like...
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.
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.
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.
Towing
The following diagram shows how you can tow another vessel. Form a “bridle” from the rear cleats...
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.
Dinghy Safety!
When it comes to dinghy operations, the following is a dangerous attitude: “It’s only a short distance ashore—jump in...
Navigation Introduction
The history of navigation is fascinating and dates back to as many centuries as we can imagine.
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...
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?
Sailboats Under Power
A Sailboat Under Engine Power is a Power-Driven Vessel Rule 3(c) The term “sailing vessel” means any vessel under sail provided that propelling machinery...
Air Conditioning on a Sailboat
Air conditioning is an enormous energy drain.
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.
Seasickness on a Bareboat Charter
Here is some education about sea sickness that can help you and your crew overcome it.

Rudder Force with Spring Lines
The rudder can be a big help because it can change the direction of the thrust force.
