STELLER SUP DESIGNS builds premium SUPs utilizing advanced materials and proprietary Epoxy Matrix construction developed by surf innovators Tamotsu and Yu Sumitomo. These SUPs are hand built and represent the most advanced constructions in the market today. 


Tamotsu Sumitomo is one of the fathers of surfing in Japan. Surfer, shaper, and innovative creator, he has contributed significantly to board construction around the world. Joined by his son Yu Sumitomo, the two continue to advance the art and science of modern surfboard and SUP design and technology, resulting in the creation of Epoxy Matrix and Thunderbolt Technologies constructions that differentiate our products from all others. Carve Sports is the exclusive distributor of products utilizing these technologies in the US. 


Utilizing advanced materials such as carbon fiber, carbon fiber/Inegra blends, PVC, hand dyed Indonesian Batik Fabrics, and highest quality components, the boards are constructed utilizing a proprietary double sandwich design that delivers outstanding performance, exceptional strength, and light weight. And they’re beautiful. 


Multi-Component internal stringer systems provide controlled flex and twist. Internal carbon fiber deck patches under the standing area are laminated on all models to reinforce the deck and prevent pressure dings in the areas that get the most abuse. From nose to tail, every detail has been thoroughly analyzed and addressed. 


The results are SUP boards that look and perform like no other SUPs in the market and are priced substantially below other manufacturers whose cost of construction is far below our hand built boards. Result: the best value in the market. By far.
