Backstay
A cascaded 16:1 backstay with a 4:1 and twin 2:1 purchases provides the power to tune the sail shape when the breeze exceeds 7 knots. The double-ended 4:1 runs forward to 29 m Carbo AirBlocks® behind the mainsheet traveler and cleats on either side of the cockpit. Using backstay tension to add mast bend and headstay tension depowers both the mainsail and the jib.
Mainsheet
57 mm Carbo AirBlocks® and a ratchet block mounted on a swiveling base on the cockpit floor make the M30's 6:1 gross-tune mainsheet system easy to adjust from any angle. A 4:1 double-ended fine-tune is lead to either side of the cockpit through 40 mm Carbo blocks, resulting in a final 24:1 purchase. A pendant (dark blue) reduces the distance between blocks for a shsorter mainsheet and faster trimming.
Mainsheet Traveler
The M30 has a double-ended captive ball bearing CB traveler system. The powerful 5:1 controls terminate on the cockpit sides next to the backstay and mainsheet for complete mainsail control by the helmsman and mainsheet trimmer.
