About Tonic of the Sea

My name is Katie Maggs and I live in the small coastal town of Penzance in Cornwall. I am a fully qualified British Sub Aqua Club (BSAC) snorkel instructor and registered snorkel centre. I learnt the basics of sea swimming and snorkelling as a child with my father in local Cornish coves and later developed a passion for the conservation of marine life and subsequent interest in marine wildlife photography. I also work as a marine mammal medic for the BDMLR (British Divers Marine Life Rescue) - carrying out seal, dolphin, porpoise and whale rescues throughout the year and I am a committee member for the Mounts Bay Marine Group whose aim is to conserve and protect our local marine environment.

As an experienced snorkel instructor and sea swimmer I am an ambassador for SwimSecure aiding safe outdoor swimming and snorkeling around the world with products designed to be safer and seen. 

I have a BAFTA nominated award winning short film 'Tonic of the Sea' available to view here and YOUTUBE The film highlights recovery from chronic stress, anxiety and burnout through daily outdoor swimming in the sea. It has been shown around the world and is currently being used in clinical practice to support individuals suffering from physical, emotional and psychological symptoms linked to stress, anxiety, exhaustion and depression.

I have written published articles for SwimSecure Psychologies, Wed, Oh, and Outdoor Swimmer magazine as well as online publications for National Newspapers. 

As a BSAC snorkel instructor I snorkel all year round along the Cornish Coast line at low tide to photograph the array of fascinating marine life found here. I offer low tide snorkel experiences for all ages and abilities and I also offer social prescribing for snorkeling for the NHS and for Age UK.
