Dual Rudder Monohulls
When a monohull sailboat has dual rudders, the boat will act with different characteristics than with a single rudder. Thus, the point of this module is to help you maneuver a dual-rudder monohull sailboat.
Charter Provisioning
Many charter companies can stock and provision your boat before you arrive. This is a good idea for the basics but there is usually little imagination in the food that is supplied.
True Wind vs. Apparent Wind
Learn the basic difference between True Wind and Apparent Wind...
Sailboat Diesel Closed Water System
The second sailboat cooling system fluid is called the closed or coolant water system.
Weighing Anchor
“Weighing the anchor” simply means raising it. If raising the anchor is to be done by hand...
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.
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.
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.
Risk of Collision when Sailing
The Rule of Risk of Collision is that every vessel shall use all available means appropriate to the prevailing circumstances...
Reefing the Sails
Before heading out, check forecasted wind conditions to see if you might need to reef at some point during the day. If so, make appropriate reefing preparations in the calm marina and ensure your crew knows the procedure.
Bilge Pumps on a Charter Boat
Boats have two types of pumps to empty bilge water; electronic and manually operated.
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.
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...
Fairlead Control
The fairlead is the first control device that the jib sheet passes through on its way back to the cockpit. You can move the fair lead forward or backward.
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.
Basic Surface Geometry
Below is a brief summary of how locations are commonly expressed on different surfaces.
Sailing Wind Velocity & Direction
The faster the boat sails into the wind, the more the apparent wind speed increases and the more it feels like it is coming from the front of the boat. They say "The apparent wind is forward of the true wind". This means the apparent wind feels like it comes from a more forward direction than the true wind.
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.
Using Prop Walk
You can use prop walk to turn your boat in a tight marina by applying forward and reverse gears at appropriate times, leaving the rudder locked to starboard.
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.
Bilge Pumps
An emergency bilge pump(s) is a very significant electrical device on any vessel. This pump is used to pump out water that may collect, for whatever reason, in the bilge.
Mediterranean Mooring – Long Line Ashore
The long-line-ashore is a useful Mediterranean mooring method. It is mostly used in the Mediterranean as a customary way of mooring a lot of boats along a shoreline.
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.
