Re: Boat Finders Fee!
The PJ40 is a semi flush deck, like the Albin Nimbus. I'd be concerned about letting the kids up and down the hatch in bad weather, more so than using a conventional companionway directly into a cockpit.
And no matter how you slice it the kids will be stowed in those tiny berths.
Then there's the gally picture, the sinks appear to be about 6" from front to back, maybe that's the photo angle, maybe they really are just big enough for a single stack of dinner plates.
Three kids, maybe two heads should be on the list?
