Motor Sailing
If the wind is light and your time is short you might want to consider motor-sailing—using your auxiliary engine...
More Basic Sail Twist
The wind at the top of the mast has more heeling leverage on the boat than the wind lower...
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.
Dinghy Safety!
When it comes to dinghy operations, the following is a dangerous attitude: “It’s only a short distance ashore—jump in...
Sailboat Diesel Water Systems
Diesel engines run hot because of high compression and therefore need to be cooled. Fortunately, ample cooling is readily available from the water the vessel is sailing in.
Mast Head pull heeling versus wind heeling
Takeaways: Standing rigging isn’t the place to economize—it’s a load-management system. Use stretchy docklines for masthead pulls, avoid shock loads, and apply smooth, steady pressure. Snatch loads break rigs.
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.
Head-on Nav Rules Situation
The Rule (a) Unless otherwise agreed when two power-driven vessels are meeting on reciprocal or nearly reciprocal...
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.
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.
Basic Surface Geometry
Below is a brief summary of how locations are commonly expressed on different surfaces.
Sailboat Balance
Below is an animation that shows the balance of forces: actually it is technically the balance of a concept called “moments.”
Understanding Energy and Power
Energy: The concept of energy is likened to water for the easiest understanding. A bucket of water holds a specific amount of water which is measured in a quantity of gallons or liters. It is finite; when it is all drained out, it is gone. To gain more, it must be replaced from a source.
Starting the Engine – Getting Familiar with a Charter Boat
Regarding the starting procedure, we’re assuming that since you’re actually commanding a sailboat you pretty much know how to turn the key and all the other safety precautions.
Vessel Lights and Shapes
Nighttime can be a beautiful time to sail. However, night vision is not the same as day vision and so rules have been established to ensure safety.
Kids on a Sailing Charter
If you're considering a charter and considering taking your kids - DO IT.
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.
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.
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.
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!
Holding a Straight Course in Sailing
Holding a straight course is an imperative skill to master as you learn to sail. As an experienced sailor, nothing is more distracting to a good day out sailing than a novice helmsperson swinging the boat in all directions.
Responsibility between Vessels Nav Rules
Every vessel has a definition of being one and only one of the below at all times. And each vessel has the ability to morph from one to the other.
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.
Plumbing and Tankage – Getting Familiar with a Charter Boat
A diaphragm pump below directs flow from the water tank(s) to various faucets throughout the boat. You'll always begin a charter with full water tanks but understand that water conservation is still required.
