During the early 1980s the Naval Reserve Detachment continued to grow in London. Within three years Prevost grew to 45 personnel. It was called the Prevost detachment of HMCS "Star" located in Hamilton. HMCS Star performed most administrative functions for the detachment. Chief Petty Officer Bill Ross was the full-time chief administrator for the growing unit. Initially only Marine Engineers were recruited as the Naval reserve had a shortage at the time, these Prevost engineers once trained, were used to augment many other units on their training weekends on board various ships on either coast.
