RE: New Raceboards
I think the phantom 320 is designed to be as long and narrow as possible within the box limits of the "hybrid raceboard class".
The designers must have decided that maximizing sub-planing performance was the way to win the most races in that class.
When races are often held in light wind, long and narrow is king. So I think the only way for shorter and wider hybrids like SB's hybrid race, hybrid formula, and phantom 301 to be competitive is if the box rules or minimum wind limits are changed, or a one-design class if formed.
