We compared the design differences between LOST's popular high-performance models, the SUB-DRIVER and F1-STUB, clearly showing photos of the actual boards and screenshots of the AKU machine's design software. *The comparison is based on board sizes of the same length of 5'10", width of 18 1/2" (47cm), and thickness of 2 1/8" (5.4cm).
Comparing the outline, the SUB-DRIVER is slightly wider and rounder than the F1-STUB.
Comparison of nose outline.
The SUB-DRIVER is slightly wider and rounder than the F1-STUB.
This is a comparison of the shapes of the center section cut into a ring. The rail shape of the "F1-STUB" is slightly thinner, while the "SUB-DRIVER" is more rounded.
The concave depth of the "F1-STUB" is slightly shallower, while that of the "SUB-DRIVER" is deeper.
If you hold the actual rail shape in your hand, you can see the difference.
The "F1-STUB" is thinner, while the "SUB-DRIVER" is more rounded.
Here's a comparison of the balance between the bottom line rocker and the overall thickness of the board. The F1-STUB has less flat rocker on the bottom, while the SUB-DRIVER has slightly more. Compare the thickness of the board from the tip of the nose and the tip of the tail, about 1/4 of the way down the board.
The thick parts of the board are more in the nose and tail of the ``SUB-DRIVER'', while the ``F1-STUB'' is thinner.
This is the easiest comparison to make with the SQUASH tail shape. The SUB-DRIVER is wider than the F1-STUB.
I recommend both boards, but the SUB-DRIVER is better when compared at the same size.
The board has a voluminous design, which means it has a lot of buoyancy and contact area, making it easier to gain speed and suitable for less powerful waves. On the other hand, the F1-STUB has more rocker and thinner rails, making it a more maneuverable and sensitive board.
