Moth Deck Layout

Mainsheet

The T2™ 57 mm Ratchamatic is the lightest ratchet we make and allows fingertip control. Both the ratchet and 40 mm T2 blocks are spliced onto the center strop. One more hangs from the boom. The blocks have strong' free-running ball bearings on curved races' making secondary bearings unnecessary and adjustments lightning fast under any load.

 

 

Vang

Current fashion incorporates a strut off the boom for the vang purchase to anchor to. The strut acts as a lever arm so the purchase is at a more effective angle. Without it' the vang would pull more forward than down. A 2:1 x 3:1 x 4:1 cascade creates a powerful 24:1 double-ended system that's adjusts easily from the wing at full foil. 18 mm Fly singles and doubles make up the bulk of this system.

 

Cunningham

Flattening the sail with the cunningham makes the boat faster and easier to control in the strong apparent wind created by a foiling Moth. 8:1 double-ended cunningham's are still commonly used systems' but top racers have switched to 18 mm Fly blocks and 8 mm lead rings to create an even higher purchase.

Class History

The International Moth has one-design roots, but 30 years of developmental rules have metamorphosed the early Moth's 110-pound, flat-bottomed hull into a 22-pound speed machine. Today's 11-foot Moths foil in 6 knots and kiss 30 in heavy air. The current design earns its international name—it is the fusion of the American Moth Boat, Swiss-inspired hiking wings, and hydrofoil design from Australia.
