BLACK RIBBON MASTC95 Introducing the ultimate wave mast. Designed together with the BLKRBN wavesail, the goal was to produce the lightest and most durable mast possible. We used the highest technology and materials available, normally reserved for C100 top line race masts, but designed it into a C95 wave mast. This means purchasing top non pregreg T800 grade carbon and prepregnating the resin in house to be able to control the process to the highest degree possible.
