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.
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.
Sailing Safety Introduction
Emergencies at sea extend from simple and almost funny episodes to major challenges that are extremely serious.
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.
Safe Speed Nav Rule
The Rule Every vessel shall at all times proceed at a safe speed so that she can...
Water and Water Making on Bareboat Charter
Aboard, drinkable water is indeed a limited supply - very limited.
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.
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.
Running Aground
In the information age, running aground is usually caused by an amateur mistake, and besides the potential damage, it is also highly embarrassing.
Leaving the Dock – End Ties
Wind pushing you away from the dock - This is the simplest scenario. Once you are confident of your plan, release and stow dock lines, then allow the wind to push the boat clear of other obstacles.
Navigation Tools
No matter the chart in use, the navigator’s work largely involves the determination of direction and distances. The most useful tools for actual chart work are...
Wind
Winds can be gentle, hardly felt, like zephyrs flitting about in a local area, or they can be vast movements of air moving swiftly across oceans and continents at low and high altitudes.
Mediterranean Mooring with an Anchor
Another factor when Mediterranean Mooring with an anchor is that the wind direction determines who is in control...
Starting the Engine – Getting Familiar with a Charter Boat
Regarding the starting procedure, we’re assuming that since you’re actually commanding a sailboat you pretty much know how to turn the key and all the other safety precautions.
Diesel Raw-Water System
Raw-water means that the water is straight from outside the boat. It might be seawater - it might be
Advanced Catamaran Maneuvering – Using the Rudders
There are some other cool things you can do when you consider the propeller thrust over a Catamaran's rudders.
Propeller Entanglement
If there is a sudden slowing or stopping of the engine while motoring it is possible that you have picked up some floating line, hopefully not from your vessel.
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.
More Basic Sail Twist
The wind at the top of the mast has more heeling leverage on the boat than the wind lower...
Sail Twist Basics
How can the wind direction be different between the top of the mast and the bottom?
Understanding Energy and Power
Energy: The concept of energy is likened to water for the easiest understanding. A bucket of water holds a specific amount of water which is measured in a quantity of gallons or liters. It is finite; when it is all drained out, it is gone. To gain more, it must be replaced from a source.
Electronic Navigation
We are well into the 21st century. Chances are that within 30 feet (10 meters) of you right now there are 2-3 GPS-enabled potentially lifesaving devices...
Typical Boat and Battery Wiring Schematic
Here is a typical wiring schematic of how your batteries are connected into your boat and charging system.
Anchoring with multiple anchors
Setting multiple anchors has multiple advantages. It reduces swing, reduces the holding load required by each anchor, and can act as a backup.
