T&T: Sealing Shorepower Receptacle on Boat-Threading it Down

[Bob/Myrna Siegel]

The cover for the shorepower attachment onboard screws down .  It has a fine
thread and is a pain to reseal in the morning when disconnecting from
shorepower.  There is a strong tendency for some crew persons to cross the
threads, making future sealing more difficult.    Anyone come up with a simple
approach to screwing down this cover easily?  Present system is to thread it
backwards until I think the threads are properly engaged and try it
clockwise.

It's a small matter but if there is a simple fix I would like to hear it.
