From time to time, including yesterday, there are pix of vessels scuffing their way into a lock. The technique is to put the ship's shoulder on the approach wall and kind of skid into the lock proper using the main engine's brute force. I've been on lakers -- shoulda asked then: this system works, obviously -- but it seems crude and by season's end, most hulls show the scars. Twelve-inch square timber rubbing strakes on the approach walls take the real wear-and-tear.. and have to be replaced regularly. Hard on trees and hulls -- has anything else ever been tried... like rollers, or Teflon*?
