To begin with, your hull was built with polyester resin and heavy coarse roving. The resin was sprayed on with a gun, and even worse may have had chopped matt sprayed on between the roving layers. So it was a weak hull to begin with. All the interior was put into place with bubble gum, adding little to the structure. Then it was sailed across the North Atlantic and into the high Arctic, flexing all the time. ( a great testimony to your seamanship). But now it has micro fractures in the brittle resin from the years of flexing, and is far weaker than new.

I understand as you do that making UMA into a proper ocean going sailboat makes no practical sense, but also know that she is an object of love as are all boats worthy of caring about.

So when I see WEST mini-pumps sitting around and you trying to mix 5/1 epoxy with little thumb sized cups I see a project where amateurs try to stick furniture together with inadequate tabbing because they tire of the laborious process of mixing and measuring by hand and having runaway exothermic cures. The last wet layup project we did in my shop consumed a 50 gallon drum of West– mixed with a large gear pump . (WEST 5/1–An excellent resin designed for room temperature wood bonding, not fiberglass lamination.) I notice that other internet boat boat builders (Matt at Duracell and Aladino at Magic Carpet) have received some sponsor assistance from Total Boat. Worth checking out. Or better yet, use vinyl ester which is more than adequate for the interior of this project.

Now is the time to tear out the last piece of interior and install a structural core to mate with the weak outer hull that is still in place. If UMA is to be your forever boat, make her your forever boat! Kika, when you watch the infusion resin flow through the entire interior of the core and laminate in a matter of a couple of hours you will find the stress flows away just like the best meditation ever!
