Been there, done that
When we purchased our 26, we had three kids 5,3,& 1. 3 years (and one more child) later, the kids (8,6,4,2) generally do well on the boat. Our rules/guidelines have been as follows.1.When in motion, kids always wear PFDs2.When away from dock, PFDs above deck, not in cabin.3.The older kids, while above deck, always know to keep one hand for the boat.4.We have one of those clip-on high chairs that clamps to the cabin table for the youngest. VERY handy during meals, or when I really need a hand on deck.5.One of you should be comfortable singlehanding, as the other is often busy with kids. But the kids need to be taught early that there are times when they need to go below and keep themselves entertained/quiet. (I find this is often pulling into a crowded harbor, right after the OB dies.)6.The younger ones (when 2 and under) need adult supervision when above deck / in the cockpit.7.Naptime is a good time to sail, the rear berth (using lifeline safety netting) makes a good crib/playpen.8.Early mornings, before the kids are awake, is a GREAT time to sail. My wife and I actually can talk and enjoy a cup of coffee together.9.Enjoy it, don't stress the kids out or let them stress you out, keep them involved, and have fun - while keeping safe.T J
