15/20 amp to 30 amp adapter

Our boat has 30 amp shore power connection. I just moved it from a marina with a locking 30 amp outlet to a marina that has household-type 115V 15/20 amp GFCI outlets at the dock. I guess I need an adapter to use the shore power. We will only use it for the trickle charger on the battery and while we are occasionally hanging out at the dock; so nothing heavy duty.

The adapters that I have seen online are $40-$50 dollars. Is this right? Does anyone have a recommendation for a cheaper source?

I made one from parts I had on hand and a foot of 10/3. You would have to source an affordable 30 amp female connector.

One caveat - mine isn't waterproof but I only use it when I am working on a boat I have unplugged from shorepower to work on the AC system.

Probably best to buy a waterproof ready made adaptor.
