short ww kayak, any misdirected rolling effort may be wasted just in causing the upside down boat to hump toward its bow or stern.
In a sea kayak, the length will help channel misdirected effort into rotation. Same applies in longer ww kayaks like the Piedra or my Animas.
Early on, "new school" designers were focused on how their designs would play or surf, and not on how they rolled. Now, companies like Jackson swear that their designs are all made and tested to roll easily.
Fortunately, most ww kayaks can be optimized for their intended roles, and optimized for your intended rolls.
