A while back, I produced a post about the way in which ships look a lot rougher when up close compared to from a distance.  In that case, it was a Washington State Ferries vessel I was considering.  In the shipyard in Victoria that was across from where we were staying, there was a catamaran ferry undergoing work.  The bow of the ship was very close to the fence and you could see exactly the same thing.  The steelwork welds were easy to see at that range and remind you that these ships are heavy engineering.
