Babysitter Needed for my Children - Full-time / Part-time

The boys are fairly self sufficient and will want to play Mincraft in the morning. They can go to the park midday/ afternoon. *They live on a boat in a Marina. There is nothing too out of the ordinary. The boat is tied to the dock and has power and water, ac, etc. Caregiver should be comfortable with the boat rocking in the harbor waves.
