Coincidentally, the other forum (cruisersforum) has a thread or 30 about pressure cookers, a couple relatively recent.
Instant Pot is one of the recommended products, an electric combination pressure cooker, slow cooker, rice cooker, saute pan, etc...
Since we've been temporarily without PC at home (our last simply wore out) and didn't yet have one on this boat anyway (for some unknown reason)... it seemed like a good time to fix that, at least for home. I just ordered the Instant Pot IP-DUO60, the 6-qt middle-of-the-lines version from Amazon.

Once I get my hands on it and can better assess size -- both for cooking and for storage -- and assuming it works as advertised, I can decide what we'll want on the boat (smaller? same?) and/or maybe larger for home?
Could make a decent addition to a galley with only a one-burner cooktop and a microwave...
