# Impact force of a wakeboarder hitting water

I'm trying to figure out what the stress level of a wakeboard is when it hits the water upon landing. I'd like to be able to compute the desired strength of a board if I were to make my own and how it would relate to the strength/thickness of fiberglass or carbonfiber around the core.

I have no experience with this type of equation and hoping someone can help me and have some fun trying to figure this out.

Lets say, 200lb rider.

Board demensions: 55" long, 18"wide in the center, 12" wide at the tips, and .75" thick. Bindings for each foot are mounted 12" from each end on center.

Ussual wake to wake jump is about 15 ft across and about 6 ft high. (so falling from 6 feet)

Boat speed is 24mph.

--If there are more variables that you need to know let me know.

Example of a board:
