What You'll Learn
Engines, transmissions, bearings, stuffing boxes, and propellers
Engines can be either inboard or outboard, with inboard engines located inside the hull and connected to a drive shaft that turns the propeller, while outboard engines are mounted directly on the transom (back) of the boat and have the propeller attached. Inboard engines are typically used for larger boats and provide more power, while outboard engines are more common for smaller boats and are easier to maintain.
Transmissions play a crucial role in controlling the speed and direction of the boat. They consist of gears that change the ratio between the engine's output and the propeller's rotation, allowing for different speeds and manoeuvrability. Transmissions also include a reverse gear, enabling the boat to move backward.
Bearings are an important component in reducing friction and ensuring smooth operation. They are typically made of durable materials such as metal or composite, and they surround the propeller shaft to minimise wear and tear.
Stuffing boxes, also known as shaft seals, are essential in preventing water from entering the boat through the propeller shaft. They consist of a gland that fits tightly around the shaft and is packed with a soft material, such as flax, to create a watertight seal.
Propellers come in various sizes and designs, depending on the type of boat and its intended use. They can be fixed-pitch or variable-pitch, with fixed-pitch propellers having a set blade angle and variable-pitch propellers allowing the blade angle to be adjusted for optimal performance.

Steering systems, autopilots, windvanes, and compasses
Steering systems are the mechanisms that allow the helmsman to control the direction of the boat. They typically consist of a wheel or a tiller connected to the rudder, which is a movable surface at the back of the boat that redirects water flow and changes the boat's heading. By turning the wheel or tiller, the helmsman can adjust the rudder's angle and, consequently, the boat's direction.
Autopilots are automated steering systems that use advanced technology to maintain a boat's course without constant human input. These systems use sensors, GPS data, and algorithms to monitor the boat's position and heading, making adjustments as needed to keep the vessel on its intended route. Autopilots are particularly useful for long-distance cruising or when the crew needs to focus on other tasks, ensuring the boat stays on course with minimal intervention.
Windvanes are simple yet effective devices that utilise wind power to assist in boat steering. They consist of a vertical vane or paddle that catches the wind, and this wind force is then transferred to the boat's steering system, helping to keep the boat on a desired heading relative to the wind. Windvanes are especially valuable for sailing vessels, as they can maintain the boat's course while conserving energy by reducing the need for constant manual steering adjustments.
Compasses are essential navigation tools that indicate direction relative to magnetic north. They provide a reference point for the boat's heading, allowing the helmsman to steer the vessel in the desired direction. Compasses come in various types, including magnetic, gyroscopic, and electronic compasses, each with its advantages and applications depending on the boat's size, type, and navigational requirements.
Together, these systems play a crucial role in boat navigation, ensuring safe and efficient travel on the water.

Rigging, splicing, line handling, block and tackle, and sail controls
Rigging is a critical aspect of a boat's setup, as it provides the structure and support for the sails. It involves the use of standing rigging, which includes the stays and shrouds that hold up the mast, and running rigging, which consists of the halyards, sheets, and other lines used to control the sails. Splicing is an important skill for boat owners, as it allows for the repair and customisation of ropes. By splicing ropes together, it is possible to create longer lines or replace worn-out sections.
Line handling is a broad term that encompasses various rope-related tasks on a boat. It includes activities such as coiling and flaking lines, securing the boat with mooring lines, and handling sheets and halyards when raising or lowering sails. Proper line handling techniques ensure the safety and efficiency of boat operations. Block and tackle systems utilise multiple pulleys, also known as blocks, to create a mechanical advantage. By changing the direction and increasing the number of force application points, these systems enable the lifting or moving of heavy loads with reduced effort.
Sail controls encompass a range of mechanisms and techniques used to adjust the sails for optimal performance. This includes controlling the angle of attack of the sails by trimming or easing the sheets, adjusting the sail shape using controls such as the cunningham or outhaul, and managing the sail area by reefing or furling. Understanding sail controls is crucial for maximising boat speed and manoeuvrability in different wind conditions.

Ground tackle
There are two primary options for setting two anchors. The simplest way is to set one from the bow and one from the stern. This will keep the boat pointed in the same direction, regardless of current or wind, but it will move side to side as much as the anchor lines allow. The other option is commonly called a Bahamian moor. Two anchors are set off the bow at a 45-degree angle, or more, to one another. This allows the boat to swing into the wind or current for a better ride.
Chain is rock solid, but when the line goes taut, a lot of force is put on your cleats or windlass. For this reason, you may want to use a snubber or bridle. A snubber is a length of nylon attached between the chain and a bow cleat so that when the boat pulls on its anchor line, the load is placed on the nylon line. Chain is also abrasion-resistant, so if you are anchoring in rocky areas or areas near coral, the chain cannot chafe. However, all that weight that helps your anchor hold also must be brought aboard.
