Logs dive. Actually, I think it would dive, depending on the speed it was

"Kayaks do not tow well. They tend to surf a boat’s wake, go broadside
and flip. Two kayaks will tow better than one if they are lashed
together at the bow and stern, creating a catamaran shape. The best
plan for towing is to put them inside your dinghy if you don’t have
enough room on the deck."
