Crew boats are vessels designed to transport offshore support personnel, deck cargo and below-deck cargo to and from offshore installations such as oil platforms, drilling rigs, drill and dive ships or wind farms. They are fast craft, with a crew of 4-5, and a passenger cabin capable of accommodating between 20 and 30 passengers. The Seacor Cheetah, a 185-foot (56.4 m) catamaran crew boat, offers a top speed in excess of 40 knots. The speed of a crew boat is dictated by economics, with the rule of thumb being that the required horsepower is proportional to the square of the velocity.

What You'll Learn
Crew boats are powered by four-six turbo-charged diesel engines
Crew boats are vessels specialised in the transport of offshore support personnel, deck cargo, and below-deck cargo such as fuel and potable water to and from offshore installations such as oil platforms, drilling rigs, drill and dive ships or wind farms. They are typically constructed of aluminium and are often powered by four to six turbo-charged diesel engines. These engines allow the boats to reach high speeds, with the rule of thumb being that the required horsepower is proportional to the square of the velocity.
Crew boats range in size from small, 30-to-60-foot (9.1 to 18.3 m) vessels working on bays, sounds and inland waterways to 200-foot (61 m) vessels that work as much as 200 nautical miles (370 km; 230 mi) offshore. The speed of these boats can vary depending on their size and purpose. For example, the Seacor Cheetah, a 185-foot (56.4 m) catamaran, has a top speed of over 40 knots, while smaller crew boats may have a lower speed.
Crew boats typically have a passenger cabin capable of accommodating between 20 and 30 passengers, with a large open deck aft capable of carrying some cargo (2-3 tonnes). They usually have a crew of 4-5, including the master, and some ports allow these boats to operate 24 hours a day, while others only permit operations during daylight hours. The usual range of this craft is 40-50 miles from their shore-based head office.

They can carry 2-3 tonnes of cargo
Crew boats are designed to transport offshore support personnel, deck cargo and below-deck cargo such as fuel and water to and from offshore installations such as oil platforms, drilling rigs, drill and dive ships or wind farms. They can carry 2-3 tonnes of cargo on a large open deck aft.
Crew boats range in size from small, 30-to-60-foot (9.1 to 18.3 m) vessels working on bays, sounds and inland waterways to 200-foot (61 m) vessels that work as much as 200 nautical miles (370 km; 230 mi) offshore. The speed of a crew boat is dictated by economics, with the rule of thumb being that the required horsepower is proportional to the square of the velocity.
Crew boats typically have a crew of 4-5, including the master, and can accommodate between 20 and 30 passengers. Some crew boats can carry up to 150 passengers, as well as 150 long tons (152 tonnes; 168 short tons) of deck cargo.
Crew boats are usually constructed of aluminium and are most often powered by four-six turbo-charged diesel engines. They are propelled by conventional ship's screws or water jets.

Crew boats can range from 30-200 feet in size
Crew boats can range from 30 to 200 feet in size. They are designed to transport offshore support personnel, deck cargo, and below-deck cargo such as fuel and potable water to and from offshore installations such as oil platforms, drilling rigs, drill and dive ships, or wind farms. They are typically constructed of aluminium and are powered by four to six turbo-charged diesel engines. The size of the crew boat dictates the distance it can travel from its shore-based head office, with smaller boats working on bays, sounds, and inland waterways, and larger vessels working up to 200 nautical miles offshore.
Crew boats are designed with a passenger cabin capable of accommodating between 20 and 30 passengers, with a large open deck aft that can carry 2-3 tonnes of cargo. They are fast craft, with a crew of 4-5, and some ports allow them to operate 24 hours a day. The rule of thumb for selecting a crew boat is that the required horsepower be proportional to the square of the velocity, so economics dictate that the boat should have as high a speed as practicable.
The Seacor Cheetah, a 185-foot catamaran crew boat, has a top speed of over 40 knots and can carry up to 150 passengers and 152 tonnes of deck cargo.

Crew boats can carry 20-30 passengers
Crew boats are vessels that are specialised in the transport of offshore support personnel, deck cargo, and below-deck cargo such as fuel and potable water to and from offshore installations such as oil platforms, drilling rigs, drill and dive ships or wind farms. They are typically constructed of aluminium and are often powered by four to six turbo-charged diesel engines.
Crew boats can carry between 20 and 30 passengers and have a crew of 4-5, including the master. They also have a large open deck aft capable of carrying some cargo (2-3 tonnes).
The speed of a crew boat depends on its size and the number of engines it has. Smaller crew boats, ranging from 30 to 60 feet (9.1 to 18.3 metres), work on bays, sounds, and inland waterways. Larger crew boats, measuring 200 feet (61 metres), can work as far as 200 nautical miles (370 kilometres or 230 miles) offshore.
The Seacor Cheetah, a 185-foot (56.4-metre) catamaran crew boat, has a top speed of over 40 knots and can carry up to 150 passengers and 150 long tons (152 tonnes or 168 short tons) of deck cargo.
The economics of crew boat operations dictate that the boat should have as high a speed as practicable. The required horsepower is proportional to the square of the velocity.
