    Gelcoat

    Such a Thing As Making the Hull Too Rigid?

    And your tabbing works kinda like leaf springs. The widest layer will flex so much... And then every smaller layer stiffens it up a bit more. This spreads the load gradually over a wider area so things bow like a spring and not like a hinge
