I had the local fiberglass expert do mine some 20 years ago, and I gave him a 6” square piece of .25” G-10 fiberglass which he glued on the inside (after sanding well), then tapered the outside of the hole out around 10 or 12 to 1, and filled up with fiberglass till it was flush. I was never able to find it from the outside since.

How many layers of glass should I be using on the outside for blocking a through-hull? Glass on the inside also, or just fill with epoxy? Some of mine have limited access on the inside for creating a taper. -- Shawn Wright shawngwri...@gmail.com S/V Callisto, 1974 C&C 35 https://www.facebook.com/SVCallisto On Tue, Mar 23, 2021 at 3:59 AM Dave S via CnC-List <cnc-list@cnc-list.com> wrote: If I get the math you are going from two through hulls to one - I did the same and removed my overboard discharge at the same time. Why not eliminate the unused holes? It needs to be done properly for sure but it’s not difficult.
