Pre-Covid, several surveyors were available in Langkawi,
Malaysia. Not all were resident. Some just visited when a
survey was needed but their more permanent base was elsewhere. That latter category included at least one resident in
Singapore who was happy to travel to most any boatyard in
Malaysia where a yacht could be hauled.
Singapore has several yacht surveyors. Look for firms with names including JM
Marine, Singapore Yacht Surveyors, Yacht Surveyors Singapore, Alpha
Marine Singapore. At least some of them, including JM Marine, would be willing to attend a yard in Malaysia.
