On the P15, Bill Swift told me about 2 months ago that it was one inch deeper than the P14 (so about 13.5”), had 2” of rocker vs the P14’s 1”, and was the same max width of 32”. He also then backtracked on the 2” of rocker and said he wasn’t 100% sure but that it was definitely more than the P14, and said he looks at so many specs it’s easy to get confused. So take those specs as possibly not perfectly accurate I guess, but it sounds interesting in any case. I’m guessing there will be a video on it in the next few weeks.
