The dimensioning of the laminate thickness is done as with ordinary sandwich laminates to meet the requirements of the classification societies....
The problem has probably rather been that the panels are too flexible. Longitudinal stringers have been required in the external templates.
Here we present a simplified construction method that directly create a hull with a perfect finish without going through the production of a mold....
My clients demand optimization, never compromises.
This approach is always crucial for the end result.
