Mast Head pull heeling versus wind heeling
A few takeaways worth sharing:
Always invest in your rig. Standing rigging isn’t the place to economize. Spreaders, shrouds, terminals—they’re not just hardware, they’re load-management systems.
Use stretchy docklines for masthead pulls. We used a 3/4" dockline, and that stretch mattered. Shock loads are the real killers. Even a small wave can create load multipliers that dwarf steady-state forces.
Smooth beats strong. Every time. No snatch loads. No jerks. Just steady pressure.

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 Balance
Below is an animation that shows the balance of forces: actually it is technically the balance of a concept called “moments.”
Getting the General Feel of Maneuvering a Catamaran
Some have compared maneuvering a catamaran with driving a bulldozer. Well . . . perhaps!
Clothing for Sailing
Dressing appropriately for weather conditions is an important but often overlooked topic. Weather in the marina may be considerably different from weather beyond the marina and conditions can drastically change during your venture.
Sailboat Diesel Engine Fluids
Diesel engines make use of a variety of fluids, including raw and coolant water, diesel fuel, and lubricating oil. A problem in the flow of any one of these fluids can cause problems...
Sailing Directions
Directions are super important because while sailing, you will always be in communication with others regarding directions of obstacles, wind changes, your destination, water current, and other boat traffic.
Seasickness on a Bareboat Charter
Here is some education about sea sickness that can help you and your crew overcome it.
Charter Local Area Familiarization
Once you’ve arrived at the charter base, the company will give you an extensive briefing on the local area, where to sail, where not to sail, and they’ll also give you a recommended route to take for the time that you have allotted.
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.
The Types of Sailing Charters
There are two types of sailing charters; captained and bareboat. The captained charters have a professional captain on board to navigate and operate the vessel, and usually...
High Wind and Gust Management in Sailing
Professional sail trimmers deal with high winds and gusts by managing the traveler and mainsheet simultaneously. The fairlead position...
Generators on a Charter Boat
Some charter boats have generators. These are small diesel engines that convert fossil fuel to DC electricity that is stored in the battery banks and AC electricity that is used to run the air conditioning, microwave, and AC outlet plugs around the boat.
Sailboats vs Sailboats Nav Rules

Know Your Chart!
Always familiarize yourself with any chart before using it for navigation and plotting of positions; there are significant differences between charts that could lead to mistakes.
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.
Sail Twist Basics
How can the wind direction be different between the top of the mast and the bottom?
Personal Flotation Devices
The terms “life jacket” and “PFD” are interchangeable, with the latter used in the USA and the former used in most of the rest of the world.
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.
Ferrying Docking Technique
Ferrying is a docking technique whereby you can maneuver your boat in high wind and current easily.
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.
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...
