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.
Global Positioning System
GPS stands for global positioning system. It uses a network of satellites in orbit. Although the GPS is used as a navigation device, it is also a form of communication to the vessel.
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.
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.
Basic Surface Geometry
Below is a brief summary of how locations are commonly expressed on different surfaces.
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...
Alternating Current and Direct Current
In your house, your wall outlets deliver alternating current (AC) electricity. The electricity provided to your house and your marina from the national electric grid is AC. Most of the devices...
Electrical Measurements
To be prepared and understand electrical power usage on a modern vessel, it is important to learn a few basic terms and concepts.
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.
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.
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.
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.
Air Conditioning on a Sailboat
Air conditioning is an enormous energy drain.
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.
Navigation Units
Sailors are forever measuring stuff. This brings us to the subject of navigation units. As we all remember from the good ol’ school days, measurement is the process of comparing something with an established standard.
Sailboat Fire Extinguishers and Requirements
Fire Extinguishers Fire Extinguishers are given a letter rating that matches the type of fire they will be battling.
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.
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.
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...
Topping Up your Energy on a Sailboat
There are several methods to top-off your energy on a sailboat.
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.
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.
Using a Marine Radio
Knowledge of use of a VHF is not only mandatory for safety but some governments require a VHF knowledge certification before you can charter a boat in their waters.
