Well, after draining my hulls of water, I remembered to put the port plug back, but then I got distracted by ??? and forgot the other one.

After sailing across the bay, I noticed I was sitting real low to the water. Oops! I went back to reach and screw it in. Well, this is the most water I've ever let in, before I noticed. The water in the hull rushed to the back, and over went the boat(as in capsize). All sorts of antics ensued, involving enthused helpers and a flurry of boats. I'd have been better off being ignored and floating to shore, but their intentions were good and no damage was done.

I'm convinced I got to figure out a system to prevent from forgetting to put the plugs back in. (Something like clipping a laundry pin onto the main sheet.) Any clever suggestions?
