General load cases for multihulls


The general load cases described in part 7 of the ISO standard are deemed too severe by cruising catamaran builders.

The French Nautical Industries Federation calls upon Gsea Design to refine these load cases.




Development of an analytical method for calculating internal stresses in the beams of cruising catamarans.

Validation of this method with two finite element models of the composite hulls of different cruising catamarans with different programs.
