Seasickness on a Bareboat Charter
Here is some education about sea sickness that can help you and your crew overcome it.
Action to Avoid Collision
When you reach the section on who is responsible to give way to whom - in certain circumstances...
Showering on a Charter Boat
Charter boat guests use the showers not only for basic hygiene, but must also rinse off seawater after swimming to avoid nasty skin rashes (sailor’s sores).
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...
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...
Sail TellTales
"Telltales" attached to the sail in strategic positions to "tell" us what the wind is doing at that exact location.
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.
Securing Your Sailboat
It is convenient to have dock lines that are pre-set to the right length with loops on the end and are permanently mounted onto the marina cleats. Now, when you return to the dock you simply slip the loops over your vessel cleats.
Magnetism
We begin with a phenomenon called magnetism. This phenomenon was known thousands of years before electricity. Magnetism was discovered...
Mast Head and Fractional Rigging
There are two variations on the standing rigging set up: Masthead and Fractional. On masthead rigs, the attachment point for the sidestays (shrouds), forestay, and backstay (if they exist) is at the top of the mast.
Anchoring Rode and Scope
To hold a sailboat, the anchor must naturally be attached to the vessel. This is accomplished by using “rode,” which is either all chain or a combination of rope (nylon line) and chain.
Topping Up your Energy on a Sailboat
There are several methods to top-off your energy on a sailboat.
Docking Maneuvers with Dual Rudders
With Dual Rudders there is no ability to spring the boat onto or off the dock! You have no water velocity over the rudders from either boat velocity or propwash.
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.
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.
Unfurling or Raising the Sails
You have motored your vessel from the slip into open water and are now ready to either unfurl or raise the sails, depending on your setup.
Electric Windlass
An electric windlass is a powerful electric winch that greatly helps in the lowering and raising the anchor.
Hull and Keel
A sailboat’s hull and keel receive considerable attention from a sailboat designer since they determine the capacity of the vessel, how fast it will go, and the degree of safety and comfort.
Weather Warnings
Weather services will also provide weather warnings, such as small craft or gale warnings for a certain area, as well as fog predictions.
Fishing on a Charter
Bring a fishing rod and reel with a 20 lb break strength line. Even if you’re not typically a fisher, few things in life are better than catching a fish for your crew, cooking it, and serving it that evening. It will increase your hero status.
Sailboat Balance
Below is an animation that shows the balance of forces: actually it is technically the balance of a concept called “moments.”
Momentum on a Sailboat
While sailboats are primarily powered by wind, the use of an engine (technically your sailboat engine is “auxiliary power”) is crucial for certain maneuvers and situations. All of this begins with understanding the momentum of a sailboat!
Understanding Weather Systems
Weather is a highly complex natural phenomenon. Globally, it is all connected and operates on a multitude of physical laws.
Holding a Constant Heading while Adjusting the Sails
We're heading to a specific point on land or a compass heading. Thus we need to keep the sails flying effectively...
