if you look closely...... you'll notice a "mark" on the starboard hull, just behind the beam mount...
interesting as it sort of seems about the same age as the damaged section of the port hull but far less severe...
closer shot of the damage ....
me thinks another cat may have been the cause of these two strikes
regardless of when / where / or whatever, these two impacts have been re-repaired and the hulls are now in a clean tidy condition.....
