We had a double blind back-to-back comparison of the Canefire 36 vs the VMax1 37 on Sunday in two identical Manta 100's with two 6.5 Severne sails. (NCS and TURBO) The Canefire outperformed the Vmax easily at all points of sail except going upwind the Vmax could keep up. She was originally pissed off that he beat her up to the point that she discovered that he had the Canefire!!
The Vmax most propably could keep up going upwind because it is slightly longer (1cm)
