Pop top down under sail
I know of a Catalina 22 that was sailing on a light wind, lazy afternoon with the pop top up. A sudden dust devil came up and knocked the boat down with such a force that one of the crew from the cockpit was thrown into the genoa (that was flat on the water). With the pop top and hatch open, the boat filled with water and sank almost instantly. Fortunately all survived, but the sailing career on one family was severely shortened. Lesson learned-chaos occurs; or words to that effect.From this observation, I have made it my personal operational standard to always have the poptop down and secured, the forward hatch secured, and the companionway hatch closed while sailing. In more windy conditions, I insist that the hatchboard be in place. I usually sail single handed so this is seldom up for discussion.I would not impose these requirements on someone elses boat. However, this is how I feel comfortable taking care of mine.On the other hand I have never heard of a Mac sinking. But I would perfer not to unload a boat full of water. It not would look good on the resume.Steve
