1 Hour Tour

The one hour tour is an excellent trip exploring the Blackwater Estuary from Mersea to Osea Island. We leave from the Hammerhead / Jetty at West Mersea heading out from the creeks. Once clear of the speed limits we head over towards Bradwell on Sea and then to Radio Caroline before heading down to Osea Island. We stop at various points of interest and fill you in on the local history. Once at Osea we head back to Mersea and stop opposite the iconic Mersea beach huts before returning. This trips departs up to 4 times a day depending on the time of year.

Green Man and the Double

For those who like a nice lunch we also offer trips that incorporates a 2-course lunch at the Green Man at Bradwell on Sea. It’s a shorter trip heading over the estuary dropping you off at the marina for a 5 minute walk for a leisurely pub meal. The trip departs a 12 noon and you are back on Mersea for 1430. The Green Man has an excellent reputation for good quality pub lunch. Check out all the reviews!

Dress Appropriately. It can be a lot cooler out on the water so please ensure you have an extra layer with you. You may also get wet and we do operate when its raining. It is worth considering water proof trousers when conditions require it


The trip is a tour and not an adrenaline style Rib ride however the boat does operate at speeds of around 30 knots which to most is fast. We stop at various locations of interest and offer some historical information as part of the tour. 

The lunch trip is less time on the water but does include a 2 course lunch at the Green Man Bradwell on Sea. https://greenmanbradwellonsea.co.uk/
