IPA: /ˈkiːl.sən/
KK: /ˈkiːl.sən/
A piece of wood or metal that is attached above the bottom part of a ship to make it stronger and more stable.
The shipbuilder installed a new keelson to ensure the vessel could withstand rough seas.
Keelson → The word originates from Middle English 'keelson', which is derived from the Old Norse 'kjóll' (meaning keel) and the suffix '-son' (meaning son or related to). A keelson is a structural element in a ship that is related to the keel, providing support and strength.
Think of the 'keel' of a ship, which is the main structural element, and remember that a 'keelson' is something that supports or is related to the keel.
