Hello Roger,

You can get a MARINCO 30 Amp plug for something like $16 at
West Marine. Still not cheap, but you won't do a whole lot
better at Home Depot. Whatever you do, please use caution.

Good luck.

I just returned in shock (as usual) from the marine store. I need to
install some fenders on our marina dock before the boat arrives. The
little dongle to let me plug a regular extension cord into the 30 amp
socket so I can use my electric drill is SIXTY BUCKS! How come a 50
foot cord with an even larger 30 amp female on the end is only fifty?

Anyway, I just need to use this thing once since the boat will become
the dongle when it gets here.

Is the 30 amp, three prong plug, a marine only item or can I get a
plug of the same kind at Home Depot and just wire it on to an old
extension cord?
