Tails The tail rocker, width, and the rail line leading into the tail are more critical than the actual shape of the end of the tail. The more width and curve in the tail, the tighter the turn and better for small waves. Less curve and width the more drawn out the turn and better for larger waves. The tail of a surfboard flavors turns in critical parts of the wave as it determines how tightly the board will hook and how much it will release. Swallow Generally speaking, swallow tails are very quick and snappy, allowing water to pass through the middle and pivot off the two points. Swallows stick in the wave a bit more and grab water through turns giving more hold. They work great on smaller boards and in quality waves. Squash This is the most popular and versatile tail –snappier than a round tail, but smoother than a swallow. A squash has the most area out on the tail block so they tend to skate through mush and generate speed really well. This tail also provides pivot points and greater release out of maneuvers. You should have at least one squash tail in your quiver. Rounded Pin This tail carves smooth, arc-like turns and works great for pocket surfers. They are easy to turn and can be surfed off the tail block or slightly forward. We have a thumb version, and a diamond version. The diamond is like a squash and a pin combined. Each can be adapted to small or overhead Surf. Pin This is a tail for serious surf. There is less area and resistance in the tail block. The rail line through the tail has fewer curves so the turning radius is more drawn out. This tail in conjunction with the straighter tail rocker is designed to hold in larger, more powerful conditions.
