Riley Balsa Surfboard vs. Polyurethane Board
------------------------------------------------
The ultimate surfboard strength test:
We have put together an experimental setup to compare the strength of a Riley balsa shortboard and a regular PU board.
The Riley board features a 100% recycled EPS core, 3mm balsa on deck and bottom and 4oz glass on deck and bottom. The board has been used for over 5 years.
The PU (Polyurethane) board has 6oz glass on the deck and 4oz on the bottom. It is brand new.
The test: A 26kg weight is dropped from different heights on the boards until they break. Check out the images or better yet the video to see what happens next.
After building over 500 boards, we are confident in their strength – that’s why we offer a 12 month warranty on all boards – solid and foam core.
