These longboards surfboards are commonly referred to as "Logs". Many renowned longboard (log) shapers still produce their highly sought after board without using modern shaping technologies. These boards do take longer to complete and some would even consider them more of a work of art than just a surfboard.
Popular longboard models include the Firewide Thunder Bolt HI4, or Aloha FUU Longboard and the all rounder In The Pink by Donald Takayama to name a few.
