Starboard just dropped me this email, about the futura speedpotential. Nice one to read. I believe the Futura is as fast as the iSonic, last time I did check the shape and it looks fast to me. I know at least 2 happy speedsurfers that have did serious speed or personal records on the futura-series.

Starboard message:
Speed surfers will often own a serious collection of highly specialized gear,
allowing them to improve their personal records, one tweak at a time. But
what happens when you ask a PWA professional to strap on a GPS and start
rigging the 2011 Futura for top speed? We called Kevin Pritchard to find out.
