The RNLI have a Lifeboat station in Baltimore (with Tamar Class and B Class Lifeboats) but the usual precautions should always be taken whether swimming or using any type of watercraft in the area.
Paddleboarders or kayakers should especially consider wind direction before setting out.
Always advise someone where you are going and what time you will be back.
The RNLI offer a great range of information on their website for all types of activities.
