A long time ago a boat builder who was in the industry for many years told me that the industry standard for the outer transom skin was if I remember right 3/8" and the inner skin was 1/4". Then Hermco once said that they should be equal....so I have still been a little confused about that. On my 1969 20sf the inner skin had only one layer of woven roving on it and it lasted over 30 years!
Generally one layer of 1708 will net you 1/16" thick laminate.
