A lifeboat sometimes has a block of zinc attached to its hull to act as a sacrificial anode. This zinc block helps prevent galvanic corrosion, which can occur when two different metals are in contact with saltwater. By corroding preferentially, the zinc protects the more critical metal components of the lifeboat's hull, extending its lifespan and ensuring safety during use.

What is the term of the device that is attached to the bottom of the hull and keeps the boat from sliding sideways through the water?
That would be its keel.
What is formula for block coefficient?
The block coefficient (CB) is calculated as the ratio of the underwater volume of a ship's hull to the volume of a rectangular block that has the same overall length, breadth, and draft as the ship. The formula for block coefficient is: [ CB = \frac{V_{ship}}{L \times B \times T} ] Where: CB = Block coefficient Vship = Underwater volume of the ship's hull L = Length of the ship B = Breadth of the ship T = Draft of the ship
What is the term for the device that is attached to the bottom of the hull and keeps you boat form sliding sideways through the water?
center board
Another name for seed shell?

What supports the sail on a sailboat?

What are outboard motors?
Motors that are mounted on the outside of a boat. The engine, gearcase, and propeller are mounted in a single case attached to the outside of the hull. Outboard motors range in size from 3 to 300 horsepower.An inboard motor is mounted inside the hull, with a propeller shaft protruding through the hull.
What are the all part of the lifeboat?
A lifeboat typically consists of several key components: the hull, which provides buoyancy and stability; the deck, which offers a safe area for passengers and crew; the seats or benches for occupants; and safety equipment like oars, life vests, and flares. Additionally, it may include a canopy for protection against the elements, a drainage system to remove water, and a means of propulsion, such as oars or an engine. Each part is designed to ensure the safety and functionality of the lifeboat in emergency situations.
What is the fin on a bottom of a ship called?
The very bottom of a ship is where you find the keel. The keel runs the full length of the ship along its centerline and is the backbone of the hull. From the keel all the frames run out and up. the hull is attached to the frames. Picture the keel as the backbone and the frames as the ribs. The hull is the watertight skin that allows the ship to float. Within the hull are compartments (rooms) and at the top of the hull is the main deck. The superstructure is built upon the main deck.
