Hull Finishing

[Jim C]

Hi,

I just completed planking a tug. It is the Anteo from Mantua. It is double
planked with limewood which I believe is close to bass wood.

Now I need to finish and water proof the hull. I am staining it and only
painting it below the water line.

Do I have to fiberglass it or simply put epoxy resin on it? The
instructions (in Italian) say to varnish it. If I use resin should I be
using
finishing resin?

All ideas and advice are welcome.

Have a Happy New Year.
