I am a Registered Pilot of the Channel Swimmers Association (CSA) and any Channel swim that I take on has to be registered with them. Please take a look at their web siite as a lot of information is to be gained there. It can be accessed by clicking on the link. Whilst aboard my boat for the swim we will supply feeding poles and any hot or warm water the swimmer may require. It is the swimmer's party that needs to supply his or her feeding food, towels, warm clothing for the return journey, etc. Every swim will have a CSA observer on board to ratify the swim.
To successfully swim the English Channel you need to be aware that more people have climbed Mount Everest than completed this swim. It is known as the top open water swim in the world. It is not like a lake; it’s salty, very rarely flat and has a tidal current - that’s not mentioning the 2 busiest shipping lanes in the world and at its best 17 degrees. To complete a swim you need to be dedicated and to have trained for it
So think very carefully before committing yourself to the challenge. Surf the net for swimmers who have completed the swim and read their advice and comments
