History

The company was founded in 2005 in York, Maine. Claiming boat building influences, Grain describes its first boards as having caulked
Caulking
Caulking is one of several different processes to seal joints or seams in various structures and certain types of piping. The oldest form of caulking is used to make the seams in wooden boats or ships watertight, by driving fibrous materials into the wedge-shaped seams between planks...

Keel
In boats and ships, keel can refer to either of two parts: a structural element, or a hydrodynamic element. These parts overlap. As the laying down of the keel is the initial step in construction of a ship, in British and American shipbuilding traditions the construction is dated from this event...

 wood is selected that blends together to form a unique pattern on the deck and bottom of the board. The keel and frames are then drilled with holes to further reduce the weight. The constructed frames and keel define the overall shape and size of the board. The installation of fins and fin-boxes (for removable fins) is aided by a builder's laser

Atmospheric pressure
Atmospheric pressure is the force per unit area exerted into a surface by the weight of air above that surface in the atmosphere of Earth . In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point...

which, without the vent, would cause air pressure inside the board to increase.
