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.

Comparison of masthead and fractional rig sailboats with labeled diagrams showing sail positions.

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.

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.

Using Spring Lines for Docking

A spring line is just a dockline that is placed strategically from the boat to the dock to help maneuver and turn the boat in place - get it safely into the dock or safely away.

Anchoring with multiple anchors

Setting multiple anchors has multiple advantages. It reduces swing, reduces the holding load required by each anchor, and can act as a backup.

Diagram illustrating true wind, apparent wind, and boat speed effects on sail, influencing sailing dynamics.

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.
