May 30, 2021 · The bar keel is made up of a flat steel bar or a steel plate of depth and thickness built to classification society requirements. It is stronger and heavier than the flat keel. Steel plates on either side of the bar keel are known as garboard strake.

Aug 10, 2020 · A bar made up of steel is placed in the centre of the keel called bar keel. Bar keel is stronger and heavier than the flat keel. Steel plates on either side of the bar keel are known as gar-board strake.

The most common type of keel is the "flat plate keel", which is fitted in most ocean-going ships and other vessels. A form of keel found on smaller vessels is the "bar keel", which may be fitted in trawlers, tugs, and smaller ferries.

The meaning of BAR KEEL is a solid keel of rectangular section in an iron or steel ship —distinguished from plate keel and trough keel.

Bar Keel > This is the first type of keel which has been used since the first iron built ship. But it doesn’t provide sufficient strength for big vessels. > A bar is placed in the center of the keel called a bar keel. > The either side of the hull attached to the bar keel is called Garboard strake

Oct 25, 2024 · The bar keel is attached to either side of the hull and these ends are known as Garboard strake. The depth of a bar usually falls between 3 to 6 times its own width. Bar keels are mostly useful for vessels that are vulnerable to grounding, for example- ferries or boats.

Sep 22, 2022 · Bar Keel. Bar steel is heavier and stronger than the flat keel. The bar keel is made of a steel bar that is flat and or a plate made of steel. You will find a steel bar at this keel’s centre. This keel consists of a bar that is supported by the frames, which run around the ship.

Bar Keel: Found in smaller ships like trawlers and ferries, it balances strength with grounding concerns. The keel’s weight counteracts the vessel’s tendency to tip. It prevents capsizing during rough seas or sudden maneuvers. As the ship sails, the keel resists sideways drift (leeway). Sailboats rely on this to maintain the course.

A little more complex, the bar keel is the only keel that protrudes (sticks out) beneath the bottom of the vessel. This type of keel was common in older wooden vessels (Viking ships, galleons, etc.) but has seen little use in the steel era as it unneccessarily increases the ship's draft without increasing it's cargo capacity.

Sep 29, 2022 · Usually, laying the keel is the first step in the construction process of most ships. The keel should be aligned with the vessel’s centreline. It has the highest degree of scantlings or dimensions for apparent reasons. Keels are primarily of three types: i) …
