Searches are continuing for two men, one from Coolungup and one from Port Kennedy, who went missing on Sunday evening after their fishing boat did not return to Coral Bay, about 1200km north of Perth.
Police say the two men believed to be in their 50s, departed Coral Bay in an eight-metre boat and failed to return by sunset.
The boat trailer and vehicle are still parked at the boat ramp at Monk Head.
Water police searched the area last night and will be joined by fixed wing aircraft, volunteer marine rescue, charter boats and ground crews on Monday morning.
Anyone that sights the vessel in the attached photograph is asked to call 131 444.
