For 100 years fishermen and boat owners have been using Gas House Quay in Harwich.
But in 3 weeks time, they've been told, they will have to leave. Hutchison Ports which owns the land says it's a health and safety decision.
We've been here 16 years as a formal association, we have a committee, members, we have our boats.
Hutchison Ports has already fenced off the quayside.
And a letter to the club leaves in no doubt their intentions - get out by midday on 12th May - anything left behind will be considered abandoned and cleared.
In a statement Hutchison Ports said:
The area has been occupied by the Small Boat Owners Association for some time but there are increasing concerns about impacts on the environment and public safety.
