Be sure to recognise that the use of Vacuum Infusion, and of Epoxy Resin, are two separate elements of construction. Just because a hull has been produced using Vacuum Infusion does not necessarily mean that Epoxy resin has been used.
I have a very useful 14 page document, explaining the equipment and process of Resin Infusion, which I am happy to email to anyone who is interested?
We are using this system with one of our principle builders as is Azimut and a couple of others now. Can be no doubt that correctly set up and with correctly controlled QC it is a far superior product
