# Let us introduce a new figure to better identify every surfboard potential!

Historically, surfboards have been described by a basic combination of length, maximum width and thickness.
More recently the board volume has been introduced and sometimes used as the main information to choose a surfboard.

Very basic informations indeed… possibly even misleading, when you consider the complexity of surfboard hydrodynamics.

Now, using a different approach supported by the latest CFD technologies, we offer a formula to measure the real
potential of the performance shortboards, for which the planing area is much more important than the total volume.

Using some simple values that any shaper or surfer can measure, the formula provides a number which,
for the first time, expresses how a board actually performs.

We called it the surf-ID.

The surf-ID number, along with usual measurements and general shape informations, will give you a better
understanding of the board potential and personality, making your choice a wiser, smarter and better one.

# Calculate the surf-ID number of your board

## Insert your board data in the form below

remember: 1 foot = 30,48 cm / 1 inch = 2,54 cm

BOARD LENGTH:
the length of your board i.e. 6 feet 1 inch

BOARD WIDTH:
the width of your board in 100/ of inch i.e. 18,75

BOARD THICKNESS:
the thickness of your board in 100/ of inch i.e. 2,25

WIDTH 12″ FROM TAIL:
the width of your board 12″ inch from tail, in 100/ of inch i.e. 14,35

WIDTH 2″ FROM TAIL:
the width of your board 2″ inch from tail, in 100/ of inch i.e. 8,06

RAIL FACTOR:
select a number accordingly to the rail thickness at wide point
