Yeah, I have thoughts. I think it is safer to keep the boat upright. I have yet to hear of any instance of a beach cat being directly struck by lightning on the water. All the reported hits that cause damage have been on land.

Occasionally, people get zapped on the water if they are touching stays or other metal or are out on the trapeze. Some of these "zaps" are temporarily debilitating.

A very experienced friend of ours said if he is working race committee on a powerboat, when lightning is in the area, he rafts up with one of the catamarans, because that is the safest place to be.

If you turtle the boat and sit on the bottom of the turtled boat, the highest point is now your head, plus you are sitting in water. Neither is good.

Just my personal opinions.
