Another performance shape born from innovation, experience and outside the box thinking. The Cornice proves that the whole is always greater than the sum of its parts.

The Cornice combines Firewire's board building expertise with design collaborator Dan Mann and Eduardo Cenzano from Trinity Technologies interpretation of an effective side-cut design for surfing. The side cut shifts volume from the middle of the board towards the tail, leading to the most effective area in contact with the water. The board literally displaces less water, leading to minimal friction and increased speed that is noticeable.

Dan Mann explains further, "...with such a narrow design, it takes less force and time to tip the board on its rail. That fast twitch sensitivity, especially on late drops or hollow waves, is where you feel the side cut really engage, and the wide tail still allows for speed in the flats".

The Firewire crew has been riding The Cornice in a wide variety of conditions, and are absolutely convinced that the design has a legitimate place alongside other high performance designs in the market today.


FST relies primarily on the PARABOLIC Balsa Rail to control flex while the high density aerospace composite vacuumed to both top and bottom decks provides significant impact strength, and is stronger than the traditional PU surfboard. Please note our boards are definitely not indestructible and if slammed by a thick lip, or if you land incorrectly in the flats after doing an aerial, it is possible to break them.

The Parabolic Balsa Rail features 12mm balsa built from 3 x 4mm strips, which as mentioned not only control flex and add strength, but also act as a buffer against rail dings. Furthermore, the long-term flex memory supplied by the balsa rails ensures boards maintain their lively feel for longer.

With a retail price point slightly above premium polyurethane surfboards, FST offers an extremely high performance, durable surfboard.

Firewire Surfboards Cornice FST Surfboard Like Snowboarding on Big WavesReview by Taeminator Taeminator
I just took a 5’ 6” (~28 L) Cornice out on a bigger day 10-12 ft faces at take off. I’m 5’7” and 155lbs. I thought I was making a big mistake when I saw everyone carrying their 6’6”+ step-ups and when I was taking set after set on the head on the paddle out. It took me 30 minutes to get past the shore break on the inside, but once I got outside, this board came to life. I had to take off a little later on the sets, but this board paddles very easily. Once you stand up, this board feels like a snowboard carving through some hard pack snow. That rail can hold at any speed. I had some big control fins setup as a quad which also helped. I don’t think I’ve ever felt so in control on such big waves before. If there was an open face, I felt I could push pretty aggressively without worrying about losing grip or speed. The narrow width of the board also made it easy to duck dive this board. I also didn’t always get my foot on the right place on the board during my pop-ups but the board still felt very in control. It’s an odd looking board but I’ve really enjoyed it in bigger punchier waves.

Firewire Surfboards Cornice FST Surfboard Cleanline great company. Real people. Cornice...Review by RatherSurf RatherSurf
Fast fast fast. Great hold. Gets in early. Good performance board. Not a performance groveler. Wants a face to carve on. Using as a quad currently. Think it will be a fun board for any type of wave that is shreddable.
