At one time it was the custom to moor vessels in the Jubilee. As there were 2 slipways and an iron grid for maintenance work, they would be moored there until it was possible to get them out of the water. They would also be moved there if it looked like they would be sailing too late to catch the lockpits as the tide fell. Daniel Clowden sank there after seacocks were accidentally left open. Here Welsbach can be seen berthed inboard of Clothilde.
