To fix the leaking and strengthen the hull I fibreglassed the outside up to the top two clinker planks and the inside to a slightly less height. This has substantially strengthened and stiffened the hull.
I then painted the dinghy with a two pot paint system and installed a new plastic rubbing strake. I also taped out a large area of the dinghy floor and painted it with non-skid paint.
Two coats of anti-fouling paint completed the job.
Moored back at the floating pontoon she is all ready to continue her job as tender to the good ship 'Mariner' and work mate to this skipper, who is glad that his feet aren't going to get wet, and gear isn't going to get soaked when rowing out to his boat. Job done.
