Sealand Swims 2024 To register your interest to swim in 2024 please email [email protected] A once in a lifetime experience! The Principality of Sealand is an old sea fort, situated in international waters, that proclaimed its independence and became a micro-nation in 1967. This is a truly memorable day. You will be taken by RIB from the port of Felixstowe where you will pass some of the biggest container ships in the world. From there the RIB will speed into the North Sea to Sealand. Conditions willing, and the humour of the Sealand guards in your favour, you may have the option of being winched up to the Principality of Sealand, where you will have your passport stamped. From there you will swim the gruelling seven miles back to the Suffolk coast. The route will take you through the Felixstowe deep water Channel which regularly hosts the passage of the largest container ships in the world. Please note this is an arduous swim and requires extremely good stamina and experience of sea swimming. It can be completed as a two person relay. Aspire work closely with the Principality and the local marine authorities (Harwich VTS) to make this swim accessible to those who want a special swimming adventure. Deposit with minimum sponsorship will be required to take part.
