Thank you for your very valid comment. However on a small vessel such as this we believe it is appropriate to have the biaxial fibres running at ±45° to the waterline to address the loading to the hull structure. On a larger more complex structure it may be fitting to have the fibres orientated to address all 4 axes. On such larger, complex structures it is recommended for an engineer to specify the exact fibre type and orientation in order to maintain the structural loading characteristics of the hull.

What is the cure time for this epoxy?
