Former Royal Navy commander Charles Howeson has been sentenced to seven years and six months for historic sexual offences against young men.
The well-known businessman was convicted back in December 2017 of 10 counts against eight young men between 1985 and 1994.
Bristol Crown Court heard how the 68-year-old assaulted his victims onboard a Devonport warship, at his home, at Drake Island tunnels and in the dark rooms at Royal William Yard.
Last week Howeson was found not guilty of two further charges against a teenage boy in Plymouth in the 1980s.
He denied all the charges.
Howeson was a champion of business in Plymouth and a supporter of several charities.
He even had a road in the city named after him after he donated the land to Plymouth City Council.
