Alan Mark, managing director, and his company, Nationwide Heating Systems, were found guilty of man-slaughter at Exeter Crown Court last month, while Princess Yachts International was fined after admitting two Health and Safety breaches.

Mark, Nationwide Heating and Ventilation and Princess Yachts International admitted failing as employers to discharge a duty under the Health and Safety at Work Act 1974, and failing as employers to meet a requirement to provide a system of work in a confined space without risk to health.

Princess Yachts International issued the following statement following the court case: "The tragic accident to Ben Pinkham, who was employed by a sub contractor working on one of our sites, and subsequent legal process, has had a profound effect on the directors and staff of Princess Yachts International plc.

From the outset, the company recognised there had been a failure to meet its own standards of Health and Safety and that failing was acknow-ledged by the company's pleas of guilty to the Health and Safety offences.

The company has throughout the investigation offered its fullest assistance to the police and Health and Safety Executive.

"We have reviewed our procedures and revised them wherever necessary and will continue to strive to achieve the highest standards of Health and Safety. The safety of the company's employees and others affected by its business remains paramount.

"Finally we wish to express once more our deepest sympathy with Ben Pinkham's family and friends."
