Communications while Underway on a Charter
Contact between vessels, or a boat and a land station, is usually carried out using VHF (Very High Frequency) radios.
Air Conditioning on a Sailboat
Air conditioning is an enormous energy drain.
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.
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...
The Engine – Getting Familiar with a Charter Boat
While this is a sailing boat propelled by the wind and mostly without the need for burning fossil fuels the most devastating breakdown besides hull failure is the engine.
Weather Predictions
While we have touched on weather concepts in this Module, no one can expect you to be a meteorologist (unless you are one) and do a good enough job at predicting the weather with enough quality to guarantee your safety.
NED Sailing Simulator
Before you play with NED, the sailing simulator, read this first. The graphic below is representative of a real wind meter on...
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.
Towing
The following diagram shows how you can tow another vessel. Form a “bridle” from the rear cleats...
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.
Sailboat Diesel Engine Operation
As noted earlier, diesel engines are sturdy and highly reliable, and operating them today is straightforward.
Springing a sailboat On and In
Coming up to a Tee-head is more the situation where you need to spring on. The need for accuracy in your maneuver is heightened when the space is tight.
The Fuel System – Getting Familiar with a Charter Boat
While it is reasonably rare to have a fuel problem on a charter it can certainly happen and you should be prepared to apply the (sometimes simple) solution below.
Sailboat Wind Power Generators
Wind-power generators are typically installed only on ocean-crossing vessels, where the vessel is away from the marina for extended periods of time and where there is a need for conserving onboard fuel.
Operating the Engine – Getting Familiar with a Charter Boat
Many modern sailboats are equipped with integrated engine throttle and transmission shift systems; called the push-pull cabling system.
Diesel Fuel
The search, discovery, refinement and resource control of fuel has a rich and very sordid history. But just like...
Safe Speed Nav Rule
The Rule Every vessel shall at all times proceed at a safe speed so that she can...
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...
Sailboats vs Sailboats Nav Rules
Sailboats On The Same Tack The Rule 12 a(ii) when both have the wind on the same...
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.
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.
Lights on ATONS
Lights are installed on some ATONS. The lights are usually alternating on and off on some consistent interval to distinguish one ATON from another.
Charter Freezer and Fridge Management
Freezers are typically top-loading and very deep. Take from home 4 -5 fabric shopping bags to stow similar items in the freezer. In doing this you...
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.
