Quote: The Twickenham slip is clear at the moment but HW(7.2m) is 15.35 on Monday, so probably 14.30 before you could launch. Parking is available beside the slip.
That said, GeoffS should be arriving around then, so the kettle will be on.
Is the launch/recovery window really only HW +/- 1 hour? Is there a slipway which gives a longer window on one tide?
