This is just a quick design of a stand up paddle board (SUP). It's designed to be completely made from carbon fiber.

| Internal skeletal structure. | 
The internal skeletal structure is made from interlocked sheets cut boards.

There are two exterior surfaces that are pre-molded before assembly. Everything is glued together with structural adhesive.

| Completed SUP. | 
The top surface is colored white to keep the board cool.

Given the construction and materials, this should be fairly light and buoyant.
