Class Information
Number: 114/284
Name: Ships > Hull or hull adjunct employing fluid dynamic forces to derive a lift or alter trim, (e.g., planing hulls, etc.) > Movably mounted hull portion or hull adjunct
Description: Device wherein a section of the hull or some attachment to the hull is mounted to be shifted relative to the hull such that it will coact with the water when the vessel is underway either to facilitate the vessel’s passage through the water or to alter the vessel’s fore-and-aft drafts relative to each other.
