The exhaust and the water outlet
Rescue Ladder.
This is fitted central on the side the boat via deck tubes, they are constructed from 1.6mm brass tube and 0,8mm brass rod, I said to myself I would not make another one but... anyway the problem is drilling the steps with a 0.8mm drill and getting the holes to line up. I could not use a centre punch as it would flatten the tube so I used a three cornered Swiss file put a mark and then part opened my small vice to rest it in and went for it. The steps still require spacing then soldering and the top bent to hook over the side.
I have made some tubes to be fitted in the deck on both sides, fortunately I only need one as it normally stored in the mid well deck by the winch.
