Our most common tail design for performance shortboards with tails averaging 13.5" to 14.5" wide. Offers width and stability in small to average size surf. The corners provide release out of turns.
FISH
A.K.A - Split or Swallow Tail. Fish tail traditionally referred to a very wide swallow or split tail, as much as 12" to 13" from point to point. Now, "Fish" seems to be a catchall phrase for any split tail design. Some surfers like a "baby swallow" on their guns. The cutout takes area and volume out of the tail while maintaining width and a straighter template line. Fish tails tend to have more "bite" in turns yet release more abruptly than a squash. The wider the split, the more noticeable the transition is from rail to rail on direction changes.
HIPS, BUMPS AND WINGS
Hip refers to a slight, gradual, increase in curve; this is template transition from the wide point into the front fins. This "break in the curve" provides a turning point or fulcrum for the rider to lever turns. A proportionately narrower nose pulls the wide point back and exaggerates the hip in various designs.
Bump is compressed, more defined hip that is typically placed at the front of the lead fins. Fairly typical in most performance shortboards.
Wings are a very well defined small step (.25" - .35") in the tail template. These small breaks in the curve help to step down width and create release or turning points. Tails 14.5" and wider will usually incorporate several sets of wings; i.e. "Catfish" or "Piranha".
ELLIPTICAL
A.K.A. - Thumbtail or Roundtail. Typically used on longer narrower boards, it keeps a good curve through the fins while maintaining some area behind the back foot. An elliptical tail in smaller surf tends to be more sensitive from rail-to-rail than a squash. Turns feel very smooth with continuity through direction changes. Curves work out best on tails 13.25" to 14.35".
ROUND FIN
For more powerful waves it is important to reduce the area in the tail. This is the most common way to maintain a clean smooth template curve on longer boards. The turns will feel drawn out and smooth. The tail shape "fits" into a rounder, hollower wave and offers more control in powerful surf.
CS FIN SYSTEM
Due to turning, changes in posit-ioning, and the constantly moving wave shape, the water flow into and around fins is always changing. The little C5 fins keep the angle of entry into the main fins more consistent, by directing the water into the leading edge of the main fins. This allows the foils on the main fins to work more effectively.
