Came across this website via Twitter (thanks to Derrick Quix) which is attempting to catalogue kayak cockpit sizes to aid deck selection/purchase.

Although it is provided by Immersion Research, it is not a designed as a sales tool, simply a collaborative effort to create a one stop spot for checking on cockpit details. If you particular kayak is not listed, would be ask you to submit the dimensions to add to the site.
