I must admit I don't understand, I'm not a native english speaker.
I probably could have been a bit more specific. The "Plastiki" is a sailing catamaran built entirely from recycled materials (the hull is empty plastic, soft drink bottles filled with CO2). Their intent is to sail parts of the Pacific to draw attention to large areas of trash, some 2X the size of Texas!!) out there. I thought a perfect match would be some of your pinhole cams, but I expect they would be difficult to use on a pitching sailboat.
