Experience tells me other wise Crunchy. I do have to profess to having "misplaced" a few items while highway towing over the years from a 4.5 metre centre console with a complete 9 inch high curtain right around the front and 3/4 of the way down both sides - including a canopy off a T-top that was removed, rolled up tight around the side bars and laid on the floor. Buckets were a regular if I forgot to lock them away or tie them in. Even lost items from within the console. I still to this day do not know how - can only assume the hull used to set up some sort of wind vortex. On my current open boat, I now use a net just so I don't lose stuff as much as meeting my legal requirements.
