Several sea channels will be temporarily closed to regular marine traffic on Sunday because of the annual Round the Island Powerboat Race.

The marine entrance to Ferry Reach, in St George’s, will be closed from 11.45am to 3.30pm or until opened by the coastguard.

The passage between Hinson’s Island in Paget and the Paget shoreline, as well as the opening between Five Star Island and the Southampton mainland, will also be closed from 12.15pm to 2.45pm or until opened by the coastguard.

Mariners, pilots and boat operators are urged to exercise extreme caution when navigating the racecourse area, particularly when near Ferry Reach, Two Rock Passage and White’s Island in Hamilton Harbour.

The public is also reminded that it is an offence for any boat operator, as well as jetskis, to fail to observe the marine notice requirements.

In the event of inclement weather, the race will occur on either Sunday, August 14, or Sunday, August 21. The same marine rules and closures will apply.
