What is a motorboat: All you need to know

When you first start out on your journey on the water, you'll no doubt think about which type of boat is right for you. And you may have considered a motorboat. So, what's a motorboat exactly? Unlike traditional boats that rely on sails or oars to move, a motorboat is powered by an engine, making it faster, more efficient, and easier to navigate.

In this guide, we'll explore five types of motorboats, looking at their uses and key features. And once you've decided on the right boat for you, all that's left to think about is which coastal waters you'll enjoy next.

1. Speedboat

As the name suggests, a speedboat is built for speed and performance. These high-powered motorboats are designed to travel quickly and smoothly across the water. They are commonly used for a wide range of activities – from recreational cruising and water sports to transportation, tours and rescue operations.

Key features:

• Hull design: Speedboats typically have a planing hull, often in a V-shape, which allows the boat to lift and glide across the water's surface rather than push through it. This design enhances both speed and stability, especially in choppy waters.
• Engine types: These boats can be powered by inboard, outboard, or stern drive engines (a hybrid of the two). Engine size and power vary widely, but high-performance speedboats can produce up to 1,000 horsepower or more.
• Size and capacity: Most speedboats range from 15 to 30 feet in length and are designed to seat around two to eight passengers, depending on the model.

2. Centre console boat

A centre console boat is a popular type of motorboat, especially for activities like fishing, diving, snorkelling, and water sports. It has a helm station located at the centre of the boat, allowing for unobstructed movement around the entire deck.

Key features:

• Open deck: Allows for easy movement around the boat, perfect for fishing or handling gear from any side.
• Outboard motors: Typically powered by one or more outboard engines, providing strong performance and easy maintenance.
• Rod holders: Most fishing-oriented models come equipped with built-in rod holders for convenience.
• Central helm station: All controls, including the steering wheel and navigation equipment, are located at the centre for balanced handling and excellent visibility.

3. Rigid inflatable boat (RIB)

A rigid inflatable boat (RIB) is a lightweight, high-performance motorboat known for its durability, stability, and speed. They are widely used in rescue operations, military and law enforcement, diving, and water sports. RIBs are designed to perform reliably even in challenging sea conditions.

Key features:

• Rigid hull: Constructed from materials like fibreglass or aluminium, the rigid hull provides strength, making the boat sturdy and capable of handling rough waters.
• Inflatable sponsons: The inflatable sides add extra buoyancy and stability, enhancing safety and comfort, especially in rough seas.
• Outboard motor: Most RIBs are powered by outboard engines, offering powerful and efficient propulsion.
• Superior manoeuvrability: RIBs are known for their quick handling, agility, and high speed, making them ideal for rapid response situations and water-based activities.

4. Cabin cruiser

A cabin cruiser is a larger, comfortable motorboat specifically designed for longer journeys on the water, including overnight stays. They are ideal for families or groups wanting a relaxing holiday experience or an overnight stay.

Ranging typically from 25 to 45 feet in length, these boats are well-suited for coastal cruising and daytime adventures on the water. Their spacious interiors and protected living areas make them a popular choice if you want to spend extended time on the water without sacrificing comfort.

Key features:

• Onboard mod-cons: A cabin cruiser has an enclosed cabin with sleeping quarters (berths) for one or more people, a kitchen area (galley), a bathroom, a dining area and sometimes a lounge space.
• Helm station: The command centre of the boat, complete with navigation controls, steering, and electronics. This may be located within the cabin or on an upper flybridge for better visibility.
• Swim platform: A flat area at the stern of the boat for easy access to the water, ideal for swimming, launching water toys, or boarding from a dock.
• Powerful propulsion: Cabin cruisers are powered by inboard, outboard, or stern-drive engines, delivering the strength and range needed for extended travel. Their engine setups allow for smooth cruising in both inland and coastal waters.

5. Pontoon boat

A pontoon boat doesn't have a traditional V-shaped hull; it has a flat deck that floats on two or three cylindrical pontoons. These pontoons, normally made of hollow aluminium tubes filled with air, create great buoyancy and stability in the water. Pontoon boats are a popular choice for recreational use, as they are spacious and have open layouts that make them ideal for larger groups.

Their stability on the water makes them a safe and comfortable option for families with children or older passengers. Pontoon boats are a popular choice for a fun day out on the water, whether you're cruising, fishing or on a tour.

Key features:

• Pontoons: Usually two or three hollow aluminium tubes that support the deck and provide buoyancy.
• Deck: This is mounted above the pontoons and is typically made from marine-grade plywood or composite materials. It offers plenty of space for seating and tables.
• Railings: Surround the deck to provide safety and support for passengers.
• Motor: Generally powered by an outboard motor, with horsepower ranging from 25 HP for leisurely cruising to 300 HP or more for towing and water sports.
