Safe Battle & Drink More Water

ESN Sea Battle is safe for everyone and promotes safe partying for all participants, so everyone can enjoy themselves. The Drink More Water initiative makes sure that everyone drinks responsibly and stays hydrated.

Goodie Bags
Every participant of the ESN Sea Battle gets a Goodie Bag with small gifts and trinkets that will forever remind you of the extraordinary experience.

No matter if you are the next Adele or prefer to sing to your shower head only, a singalong session with the other participants is always programmed to be fun.

Enjoy the onboard entertainment from the Tallink Silja Line including live performances and Troubadour. You can also join the pre-event in Stockholm to get a first taste of what the festival on the sea will be like.
