Install a full bridgedeck and reduce the volume of water the cockpit can hold in the case of the boat being pooped. I did this on my boat, since the boat companionway was a only three inches high, and we'd get water down below in heavy weather if the crew forgot to replace the bottom dropboard. The bridgedeck I added takes up almost FIVE CUBIC FEET of the cockpit, reducing the amount of water the cockpit can hold by over 300 lbs. It also is a couple inches taller than the transom, so if the boat does get pooped, the water will pour out the cockpit drains and transom, and not into the cabin.
A few notes on Benny's recommendations—First, the VHF should be a Class D DSC-capable VHF unit and connected to a GPS. Second, the through-hulls should also have softwood plugs in plastic bags tied to them. The plugs should fit the through-hull, and should have a lanyard and a hole drilled through the fat end, so that they can be lashed into place. Third, the PFDs should have retro-reflective tape, strobes and whistles on them, and preferably have harnesses with crotch straps—and you should have jacklines and tethers as well. Fourth—learn to reef early, and practice reefing until you can do it in all conditions in under two-to-three minutes.
