Sailing Class - Sailboat Structure

Like most sports, sailing also has its own unique terminology. This term may seem complicated at first sight, but when you are familiar with the relevant vocabulary, you can quickly grasp it. Let us first look at the main components of the sailboat and the specific terms.

1. Hull

There are two kinds of hulls for sailing boats: single and multiple bodies.

In general, multi-hull vessels are faster than monohulls. The front of the hull is called a bow. The stern is generally more pointed, however a sailing boat less than 10 feet in length may use a square stern, such as an OP-class sailing boat.

The rear of the hull is called a stern. The stern is generally wider and has a flat, vertical surface called the stern side. The port of the sailboat is generally marked with a red mark and the starboard side with a green mark. Beginners often stick red and green tapes to prominent positions on both sides of the sailboat.

2, principle

When the sailboat floats, its own weight is equal to the weight of the water it discharges, so the weight of the sailboat is also called “displacement”. The line of contact between the water and the hull is called the "waterline" or "waterline" and is generally marked.

In order to prevent the wind from leaving the route, most of the sailing hulls are equipped with keels or central plates. The central board can be raised or lowered by pivoting, or can be lifted or lowered; the keel is fixed and has a certain weight and can be used as a ballast to balance the wind's offset thrust. On a sailboat with a central board, the aviator's weight can be used to balance the hull's pressurizer.

The rudder can be used to maintain and change course. The helmsman controls the heading by manipulating the tiller and extension rods. The actual sailing direction of the sailboat is opposite to the direction of pushing and pulling the tiller.

3, sailing equipment

The equipment above the sailing hull mainly includes sails, masts and rigging

Sailing boats generally have a single sail or multiple sails. Sailboats are more common and usually include a mainsail and a triangular front sail. The mast is used to support the sail. Some small sailboats do not require rigging that supports boring bars, and most sailboat types require moorings. The connecting line between the mast and the hull is called a stay. The connection between the mast and the stern is called the front stay, and the connection between the mast and the stern is called the backstay. The rigging used to operate the sails is called the rigging and they include: mainsail rigging, frontsail rigging, backstaying, mainsaillifting, pulldown, and cable stays or sails. Wait.

Winches are used to secure and coil rigging. The bollards (clamps, horns, bar clamps) have teeth in them to reinforce the fixed rigging.
