Square One

Square One is Stretch's three-fin design built around decades of work with thrusters. The maker describes a continuous, neutral rocker and a wide point centered along the board. Stretch links that layout to paddling, predictable handling and carrying speed, with the rocker intended to accommodate surfers who emphasize either the front or back foot.

The model page lists a three-fin setup with Futures or FCS II systems. Material, size and fin-configuration choices are presented separately when ordering. The design description gives Square One a clear thruster identity without assigning a single construction or a particular wave-size window to every board.
