Looking for some experts out there to see what affects 2x4 oz glass on the top and 1x4 oz glass on the bottom vs 2x6 oz glass on the top and 1x6 oz glass on the bottom

  • If one uses the surfboard carefully 3 x times a week - 4 hours each day - expecting the board to last a while (few years) but concerned about cost and;
  • Overall weight, strength and flex distribution of the surfboard
  • There’s always a trade-off.

Get a group of surfers together and you get different answers to describe their perfect surfboard:

  • Most would say “super lightweight and super strong!”
  • To get “lightweight and strong!” with present day technology (not using Varial - the cost) this includes the number of layers of fiberglass cloth on both the deck and the bottom of the board, and the weights of each layer of fiberglass cloth.

To get things started:

  • There are different types of fiberglass cloth - some will provide more strength with 4oz (like S-glass) than standard 4oz cloth - this glass could increase the weight by 20%
