As I said in the last post, I found a bunch of pinholes in the starboard side rubrail. Some light tapping with a hammer really opened them up. So out came the oxy-acetylene torch to take off the old half round iron pipe and prepare the area for a new section of mild steel half round pipe.
So here it is after ripping off 5 feet or so and sandblasting the area.
There are more holes farther forward so more cutting. You can see all the spongy crap that accumulated inside and held all the moisture. These outlets are the discharge from the deck drains. All the snow on deck is melting!
