  • Construction: The Base Construction is a polyurethane blank with polyester resin. This construction is highly versatile and suitable for all round professional performance. Fourth Surfboards use high quality materials to create premium surfboards. US Blanks at the core in blue foam and Hexcel Glass for the laminate bonded with Silmar resin creates a balance of durability and weight for the best performance
  • These boards are finished in a 24/7 temperature control room to ensure that the curing times are at optimum levels. To finish the board it's sanded to a 240 dry sand finish, removing any plastic lacquer left on the board which will feel and look horrible after a few months in the sea
  • Outline: Classic teardrop shape with a fuller nose
  • Tail: Swallow tail with extra curve increases your balance and give the board plenty of pivot to increase the response
  • Concave: Single throughout to provide plenty of lift
  • Rails: Boxy performance 60/40
  • Volume: Medium volume is more than a standard shortboard, with a extra volume under the torso to support paddling
  • Fin set up: Thruster fin system combines the manoeuvrability of a twin fin with the added hold of a central single fin. This system gives you control and speed down the line for a good bend of control and down the line speed
  • Fins not included
  • Suitable conditions: Small waves
  • This is an all rounder high performance board that that just as comfortable in the air as it is on the rail. It's fast and should be ridden head height or slightly shorter

The Belly Shank is a great all-rounder surfboard that dominates on small waves bringing speed, drive and a bit of flare to the ride. The Belly Shank design is simple yet effective, created with performance in mind.

The concave runs from the nose to the tail creating lots of lift, whilst the teardrop shape with extra curve in the tail pivots effortlessly and increases response. The nose is wider to give you balance and stability, this shape ensures that the board remains mobile at low speeds yet feels free on the rails

The Belly Shank construction allows the board to effortlessly carve and rail surf. It feels like a standard shortboard but features harder edges slightly higher up, this offers a nice platform off the bottom and give the board plenty of release in the turns. These rails compliment the wider swallow tail. At high speeds you can really push and drive the Belly Shank thanks to belly channels.
