Mainsheet
The C Scow has a big, big main that needs constant adjustment to keep the boat on its rail. It needs blocks that are strong, light, and efficient under load. The 4:1 mainsheet system is made up of 57 mm Carbo T2 blocks and a 75 mm ratchet that sheets off the backbone.

Traveler
Being able to easily control the camber of the main and the twist of the leach makes all the difference in boat speed, making the cunningham one of the most important controls on a fully-battened mainsail like the Nacra 17. This system uses a combination of Carbo, T18, and high-strength blocks for an 8:1 double-ended system that can be reached from either tack. Two Carbo pivoting lead blocks (headknockers) on each side of the mast swing side-to-side, enabling crew to easily adjust the cunningham from either side of the boat.
Vang
With its rotating mast, its large main, and a deck that extends well behind the mast, the C Scow requires a very powerful vang. The vang is attached to a Small Boat high-load curved-race traveler car on a U-shaped track. All the purchase of this highly-loaded vang is belowdeck and out of the way of the crew.
