Take Note When the Boat Heels Over or Stands Up
At a sailing group meeting, someone mentioned they were having trouble determining if the boat was pinching or not.
Dock Line Release
Have a dock line untying plan based on the wind and the current direction and then communicate this to the crew. Depending on which is stronger...
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.
Sea Anchor
Finally, there is something called a “sea anchor.” These can be a variety of devices used to slow down a vessel caught in high winds and turbulent seas.
Sailboat Balance
Below is an animation that shows the balance of forces: actually it is technically the balance of a concept called “moments.”
Boat and Equipment Emergencies
The character MacGyver in the TV show of the same name would have made a great sailor. Why? Because he could fix anything and a boat is a concoction of a kajillion gadgets busting to rot...
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 Battery Charging
Like a water bucket, batteries have a specific storage capacity and must be refilled/recharged when their contents of energy are depleted.
Typical Boat and Battery Wiring Schematic
Here is a typical wiring schematic of how your batteries are connected into your boat and charging system.
Magnetism
We begin with a phenomenon called magnetism. This phenomenon was known thousands of years before electricity. Magnetism was discovered...
Sailing to a Mooring Ball
Sailing up to a mooring ball is an advanced skill. It will definitely prove your finesse for handling the boat and managing the crew.
Understanding Weather Systems
Weather is a highly complex natural phenomenon. Globally, it is all connected and operates on a multitude of physical laws.
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.
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.
Catamaran Maneuvering Mastery
As now learned, Cats can turn inside their own length, they can vector sideways, and using the bulldozer effect you can instantly rotate the Cat to point in any direction, you can do almost anything.
Winged Sail Vector Diagrams
Sail and Winged Sail Wind Force Vector Diagrams. And it's highly relevant right now because of the America's Cup AC45 catamarans using winged sails.
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...
Best Angle to the Wind when Sailing
Here's a diagram to show you what "degrees off the wind" means. Sails, unlike wings, get their shape from the wind pressure against the fabric....
Sailboat Generator or Large Battery Bank?
Dedicated electric generators on board sailboats are usually only reserved for large sailboats because of their weight and size. Unless there is a desire for large amounts of electricity...
Sails
Sails are sophisticated objects. It is not only the materials they are made from that are important, but also, the way they are cut and sewn.
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.
Bilge Pumps on a Charter Boat
Boats have two types of pumps to empty bilge water; electronic and manually operated.
Sailboat Diesel Engine
Thanks go to Mr. Rudolf Diesel who years ago in Germany cleverly invented an engine that today bears his name (luckily, they chose to use his last name)—the sailboat diesel engine.
Starting the Diesel Engine
Prior to starting the diesel engine: Become familiar with how and when a vessel’s transmission gear shift...
