THE 39th World Tin Bath Championships take place in the middle harbour in Castletown tomorrow.
Starting at 3pm, the event is run by the Castletown Ale Drinkers' Society and has attracted more than 70 competitors from around the world.
The men's entry is headed by Lee Cain who returns to defend his title.
In the women's race 12 times winner Erika Cowen returns.
Plus there are the team races too.
And if that wasn't enough action the Manx National Snake Race Championships will see teams of four men and two women paddle rubber tubes backwards down the harbour.
During the afternoon intrepid birdmen and women will make attempts at man powered flight and the Castletown band will play from 2pm to 3pm.
Port St Mary lifeboat will be in attendance in case of any bath wrecks and Phil Taubman will be the compere for the day.
Spokesman Dave Collister said: "Come along to the World Tin Bath Championships at the tin bath racing capital of the world - Castletown - and enjoy two hours of slapstick stunts and family entertainment."
All proceeds go to local charity.
