Mainsheet System
The 4:1 mainsheet is centered on the boom with a 40 mm traveler block on a rope bridal that spans the cockpit directly in front of the 57 mm ratchet block. A pair of 40 mm T2 Loop blocks is secured onto the boom for the lightest, knot free attachment. When the breeze softens, untie the knot on the traveler block to go from 4:1 to 3:1 for quicker sheeting.
Cunningham
The double-ended cunningham uses two 18 mm Fly doubles and one 18 mm single for a strong, light, and easily rigged/unrigged system. To rig, pass the tail end of the cunningham line through the grommet on the sail and tie a knot on the opposite side of the gooseneck. The 8:1 system is easily adjusted from a full hike.
Vang
The center lead vang's 16:1 purchase is made up of 18 mm Fly blocks and 16 mm stainless steel blocks, providing lots of power in a small package. The various Aero rigs require slightly different vang line lengths. Lines can usually be tightened/loosened by altering the length of the strop at the bottom of the mast.
