Thanks to those revolutionary, V-banked, caged rollers that helped name it, its pre-preg carbon or aluminum sideplates, and its titanium sheaves, V is the block most efficient in freeing performance from friction Harken has ever made…so far. This performance does not require custom arrangements. We make V-blocks every day — for anyone. Perhaps including that boat ready to pull the trigger immediately to leeward of you on the starting line.
