you have a one year old - that's endangerment. They can't walk without falling on level, stable ground. A rocking boat that typically has only guy lines on the edges isn't exactly a safe environment for them. Anyone that's watched a kid that young could tell you how fast they move or roll or fall. Even worse would be if they were confining the kid to the interior only.

I could care less if the kid was, say, 5.

As for reckless .... arguable. If the only experience they have is running ships up and down the coast doing deliveries, I'd be tempted to say they aren't experienced enough for the open ocean. Book smarts and passing USCG tests doesn't make you a master sailor. It just makes you a qualified one.
