T Semi- Guns should just feel like an extension of your short board. Designed for bigger waves, easier to paddle in but also still have the performance to throw the thing around if your want to. I shape a lot of these for guns off to Indonesia mainly, but also South America and other South Pacific islands.
They are refined through there nose and tail with a little meat under your chest  for ease of paddling and usually a nice single/double concave with slight flat or Vee running out the tail. The rails are pulled down and refined so they hang into the wall nicely. It has a nice continuous rocker for a smooth but powerful ride. Available in quad set up to.
