You should be ok from Benn`s advice, just in case, Alan Clark at Balmain Marina is senior in years, knows his stuff, and has a strong reputation for competence. Calls himself Birchgrove Yacht Service. His employed mechanic, Tom, is good too. I can`t say he has Gardner experience but he`s old enough to know Gardners, or might know someone who does. He can be slow at times getting onto a job. Phone 0424735164/98106267.
