A wooden shield used on board English warships of the Tudor navy to line the fore and after castles. They were usually painted with the heraldic arms of the admiral, captain, or other noblemen on board, and in later Tudor times were extended to line the waist of the ship as well as the fore and after castles. They were primarily intended as a protection for men on deck against small shot from enemy ships, and were made of poplar, which did not splinter when pierced. Later they became much more of a form of ship decoration than of protection in days when warships were highly carved, gilded, and painted. They were copies from the shield protection which lined the gunwales of the Viking longships.
