What are the differences between carbon and regular fiberglass skimboards?
Carbon fiber is a much stronger and stiffer fabric than fiberglass. By weight it is over 100% stronger and 100% stiffer. Most skimboards however only have one sheet of carbon fiber on each side. So the resulting skimboards are roughly the same strength even though they have stronger fabric in them. But carbon fiber boards are significantly stiffer than regular fiberglass boards. That turns out to be the main difference between boards made with the two materials.
