Let the kids on deck if they want to as long as they can keep out of the way - or help. Puke is easier to clean off decks than from the cabin. Just do life jackets and harnesses. Harnesses are manditory on our boat: after dark; in big blows; outside of the cockpit in anything rough. Photos look like a standard cold front squall line with a few goddies extra. Usually evaporates into a nice sunset. I watched a nice roll cloud attack the marina a few weeks ago. Nothing but nice after it passed. Sometimes on the water our vista is way greater than on land. Just be prepared.
Speaking of big sails, I just discovered the sail I thought was a standard kite turned out to be a monster asymetrical; about a 200 % Geny. (Mast 80, foot about 40). First time out of the bag after four years of restoration and learn as you go. We've been running a fun combo of two jibs, main, mizzen, mizzen staysail. It gives about 9.5 with 12 on the beam. I'm sure the kite will throw us over 10.
