Be aware that if you draw more than 15 amps from the shore, you are
overloading your 15a male and female connectors, with some probably
small
risk of fire or, more likely, melting the plastic parts of the
connectors.
Better would be to wire the 20a male to a 30a female.

Another way to overcome this would be to use individual plugs, a
female 30, a male 20 and a male15 and wire them in a sort-of 'Y'
configuration with 12 and 14 gauge. That would give you a universal
connector that you could use with your normal shore power cord
whether you have a 15, 20 or 30 Amp outlrt at the marina or club.
Unfortunately I couldn't do this as my  original 15 to 30 is all one
piece plastic molded.
You would need individual plugs at a cost of about total $50.-

BTW: Hal, this was originally a list question and I'm putting my
answer back there - the problem is/could be of universal interest.

Not a good idea,  this would be a real shock hazard to someone...jd

CAUTION
This would of course necessitate insulating the unused male plug as
you otherwise would have a real good shock hazard.  I therefore
withdraw this suggestion as not a good idea - George
The other solution of male 20 to female 15; male 15 to female 30
works as long as you do not intend to draw more than 15 Amp. It is
indeed what I have been using for years. - Gg
