The old Sealand club used to have a very large 6 cable winch, which

launch 6 sequentially, before the land-rover had to bring all the cables

used at other RAF gliding sites.

The club you refer to at Sealand was actually an Air Cadet Gliding
Squadron (used to be school) and the standard equipement was the Munster
van Gelder winch.
