Gracias Ness, demasiado gentil para conmigo
Te cuento que seria preferible acometieras la fabricacion con un nucleo de
glekecell, divinycell por ser espuma de alveolos cerrados y nula absorcion de agua,quizas algo mas cara que la otra pero mas fiable de resultado final.

Acerca de esto cuenta Sven Yrvind de la fabricacion de su ultimo barco "cabohornero"
"
A different way for an object to lessen the damage of an impact is to deform and spread it out over a longer time. Do another experiment. Put a piece of rubber on a rock and hit it with a hammer. The rubber deforms, but does not crack.
Yrvind ½ is designed with these two interesting facts in mind. First, she is light enough to move away when hit and her lightness also ensures that she creates less impact when she runs into something. Second, since the 1980’s I have built my boats using an atypically thick sandwich core, in combination with a very strong inner skin. When hit with a blow that would be fatal to a production boat, the outer skin breaks and the foam gets crushed. This absorbs the collision energy and distributes the impact over a large area. The already strong inner skin is less strained, and the boat is not holed. My small boats built along these principles are for all practical purposes indestructible. Any damage is cosmetic and can easily be touched up in the next port."
