SLNS Sayurala (P623) (Sayurala meaning: Sea waves) was an Offshore Patrol Vessel (OPV) of the Sri Lanka Navy. It was named as the CGS Vigraha (39), a Vikram class offshore patrol craft of the Indian Coast Guard. She was in service in Sri Lanka from 2009 to 2011, during the Sri Lankan Civil War.
Sayurala was tasked with deep sea patrolling both within the Sri Lankan territorial waters and in international waters to curb possible arms smuggling during the Sri Lankan Civil War. She was returned to the Indian Coast Guard in 2008.
Commissioned on 12 April 1990, CGS Vigraha (39) served with the Indian Coast Guard until she was transferred to the Sri Lanka Navy.
