The reminder comes just after the crew rescued people cut off by the tide near St Mary's Well Bay for the second time in just two weeks
The most recent rescue was last Thursday (30 Aug) when helmsman Nathan Cummins and his volunteer crew of Karl Lawrence and Alex Kalebic launched Penarth's inshore lifeboat at 6pm.
As they approached St Mary's Well Bay, they spotted a man and a woman trapped against the cliff edge as the tide came further and further in. The crew took the boat up onto the very small area of beach that was left and helped the pair in. They then dropped them off further around the coast at Lavernock beach.
RNLI helmsman Nathan Cummins said:
'The tides around Penarth's coast can come in very quickly and catch people unaware. It's vital to check the tide times before you set out and allow plenty of time to get to your destination around the coast.'
Penarth's larger Atlantic 85 lifeboat was launched on 2 September to a report of a 20 foot sailing boat in trouble two miles off St Mary's Well Bay. Helmed by Mal Hopkin and crewed by Geraint Williams, Alex Kalebic and Owain Davies, the boat made its way to the stricken vessel which had drifted from its original position further towards Barry Dock as a result of its engine and steering failure.
When the lifeboat crew reached the sailing boat, it had already been taken under tow Barry Dock's pilot boat so once they had made sure the one man on board the sailing boat was fit and well. The crew returned to Penarth Lifeboat Station.
