The essence of foil.

I’ve looked up the word foil in the dictionary but don’t find a definition that comes close at all to what in surfboard lingo we call foil. Unless you think a blunt sword is close.

Once you get bit by the surfing bug and develop your abilities surfing and have handled a few different surfboards the chances of realizing the beauty of a fine foiled surfboard and getting hooked on the look is pretty strong. To the discriminating surfer a surfboard can become a piece of art. Short board, long board and anything in between can be a sculpted thing of beauty.

Simple lines, simple curves and how they are formed and fit together when done well can be something very pleasing to look at. It can take years to acquire the ability to sculpt a piece of art. Taking what you see in your head and using imagination and your hands to make what you see, be pleased with what you see and have others enjoy what has been crafted.

So what is foil? To me it’s the complete package of curves that make a surfboard. From how the deck curve relates to the bottom rocker curve which in turn dictates how the foam volume is distributed nose to tail. How the rail line and rail shape moves along the length of the board, as well the way the deck and bottom is crafted from rail to rail.

It starts with a profile. Cutting a surfboard in half from nose to tail at the center and seeing how the bottom and deck curves relate to each other. The look of a profile will depend on the surfboard itself and the boards intended use. It may have more thickness a little forward or a little more aft or have an even taper. How the volume graduates into the nose as the deck and bottom curves converge, how the tail lines flow. It’s all in the profile.

Deck crown may blend it’s way from rail to rail down the length of the board with more curve forward and flatten out the back as the profile tapers through the tail section. And as the profile tapers the rails turn with crisp edges sharpened for a positive cut on the wave face.

There really is no formula for a nice clean foil. We may have some what standard bottom rockers or typical bottom curves but how the deck lines work with bottom lines? It can be very personal to a shapers hand. CAD programs may make seeing a given profile easy. But, seeing something on paper and then seeing the same thing full scale with all the other elements can be a completely different thing. There is no easy way to a nice foil.

Once you get the look of a nice foil in your head it just doesn’t go away… a picture impression. If you have a finely foiled surfboard you can look at it for hours and never tire it's look.

The beauty of a finely foiled machine, you see it with your eyes, feel it with you hands and almost instantly know it will feel good under your feet.
