Seacocks – Getting Familiar with a Charter Boat

Seacocks are designed to let water flow out of the hull safely. They are not one-way valves so any loose clamps around the seacock itself create leaks around the hoses and can allow water to enter into the boat. This is usually bad – right?

Rigging

At boat shows, we see folks huddled down in the vessel’s salon oohing and aahing at the leather cushions to sit on, and at the electronic gadgets for navigation and entertainment.

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.

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.
