From the ships operated by the ROKN, the Noryang-class PCEC (Patrol Craft Escort & Combatant) (ex-PCE-842-class) had the best size for the mission, and the Sinseong-class PCE (Patrol Craft Escort) (ex-Auk-class MSF), which had U-shape hull, showed the best ship stability at the patrol speed (5-8 knots).
The ROKN's ships provided various alternatives for the task. The Noryang-class PCEC was found to be well-suited in terms of size, while the Sinseong-class PCE proved to be more stable when patrolling at speeds between 5 and 8 knots.
