The weight has been reduced by eliminating all unnecessary plastic while increasing the cross- section of stainless steel parts for increased strength.This part can now withstand over 900kg of downhaul load twice as much as used on the largest racing sails.
The special geometry with tilt bottom pulley makes perfect sail pulley/rope alignment. This allows the sail to be downhauled all the way down (block-to-block) and it reduces downhauling friction.
