This is the Thunderbolt from Bradley Surfboards and this one is the 5'10" x 20 3/8" x 2 1/2" with 33 Litres and Futures fin boxes. Great step down surfboard for weaker waves, but keeping the high performance in groveller conditions. This is also available to preorder, just check the pre order product.

Here's what Bradley says about it;

The Thunderbolt has been reworked with a slightly lifted tail and Bradley's all-new super squash tail. The super squash size is spot on for acceleration.  Full volume through the front half of the board with a flat entry-level rocker for extra speed. The slight lift in the tail will enable any surfer to pivot easily. Aggressive and progressive surfing. Designed to be an extension of your regular shortboard in a package suited for small surf.  Everything about this board is about extracting performance from the board in extremely weak waves.  A design with summer performance fun in mind taken from the original swallow tail Thunderbolt.  Slight single to double concave giving the board both lift and hold in the pocket.
