It’s a simple idea – so simple it’s perhaps surprising nobody thought of it before – but now the RNLI has installed a signboard on Sully Island to warn visitors that they are indeed standing on an island which is – twice a day – completely surrounded by the sea.
Penarth lifeboat is tasked by HM Coastguard on scores of occasions every year to pick up people who find themselves marooned on Sully Island as the tidal causeway linking it to the mainland is submerged at high tide. No fewer that 14 people have been ferried ashore by lifeboat in the last two weeks.
It’s hoped that the sign now installed on the island itself will act as an immediate reminder of the risks and will avert further call-outs.
An RNLI traffic light tide-warning system was installed at Swanbridge at the point where the natural causeway to the island joins the mainland – giving visits a clear indicatrion of how much time they can safely spend on the island before the tide cuts them off – but it still seems once they’re on the island all too many visitors lose track of time.
The new signboard on the island details the risks to be considered when visiting Sully Island and gives essential safety advice.
Jason Dunlop, Penarth RNLI lifeboat operations manager, says “We hope these news signs on Sully Island will complement the existing safety measures to help increase awareness around the risks of walking to and from the island.”
