Thanks Frank I really appreciate your offer.
I want to try get it into a welder as I have other plans for the boat also so would prefer to get it welded up, but may take up your offer if I don’t get anywhere.
if the small amount of work is an issue to getting it in to a welder and getting it looked at I will discuss the other works I want to do, such as welding in a rear step, electric motor mount and bracing to mount a floor.
the boat isn’t too old, 2000 model from memory, but has been unused for many years sitting on the salty skids, which has caused the issue. without removing the skids from the trailer the extent of the issue wasn’t entirely evident.
thank you again for your kind offer.
