movement is a product of the previously mentioned
open-minded trend towards experimentation. If you
want to truly understand the history of surfboard
design, it makes perfect sense to try a single fin.
Surfing one will help you see why the advent of the
twin fin and thruster were such significant turning
points in the evolution of surfboard design.
The single fin’s template features a wide point
forward of center and the thickest point of a single
fin is also past center. Having more volume under
your chest makes this type of board easy to paddle
offering high wave catching ability. By moving the
widest point forward (which also creates a
straighter and narrower tail), the single fin
outline encourages the board to track down the line.
The typical single fin bottom features vee starting
from the center of the board and flowing to the tail
which helps to counter the straightness of the
outline and allow the board to roll from rail to
rail much more freely.
Single fins can work in any size surf but surfer
beware, you'll need to nurse your turns in order to
keep the fin from releasing and causing the dreaded
spin out. As mentioned previously, riding this
design will offer you a greater appreciation of the
effortless turning modern surfboard designs provide.
Because of the added volume and ease of paddling
inherent to this design, retro surfboards can work
for a variety of abilities anywhere from from a
total beginner to the more advanced surfer
