The 2012 Start M and L have been lengthened to 285cm to hugely improve the boards' glide in light winds. With the longer length, the profile of the board can flattened, which also allows the board to gradually transition into planing mode - smoothly and easily, without the need to overcome a power surge.
The Start's tail design is also wider than any other entry-level board. This allows the Start to get planing earlier, at lower speeds. Again, this helps beginners to plane smoothly and easily.
