Hi, I hope some one can clarify this for me.
I had a look at an Aluminium hulled rib some months ago, there was signs of corrosion above the waterline (bubbled paintwork), which could have been fixed. But what concerned me more was the possibility of corrosion inside the hull.
1. How can you detect it
2. How can you fix it
I have no idea if there are inspection hatches or the like, but I do know that unprotected aluminium in salt water can corrode quite quickly. There is marine grade aluminium, but if this boat was made of it, then it will still corrode.
I would imagine that there could be problems with electrolysis as well.
