"Many 470 teams fit out their own boats and personalize their systems, so there’s a variety of deck layouts. In general, Carbos are the blocks of choice: 40 mm (2650) on the boom for the mainsheet, 40 mm (or even 29 mm) blocks on the stern, and 57 mm (sometimes 40 mm) ratchets for spinnaker sheets. The 57 mm cheek ratchets (2137) are popular for jib sheets. Harken’s line of ratchets and Ratchamatics® gives sailors a wide range of equipment choices for main, spinnaker and jib systems."

Spinnaker System
This system is all about speed. A 1:2 reverse purchase on the halyard quickly hoists the spinnaker while a 1:5 shock-cord halyard take-up system automatically manages accumulating line during the rapid chute deployment. A control in the cockpit drops the sail.

Vang
The cascaded vang has a powerful 16:1 mechanical advantage. The skipper can play the vang from either side of the boat
Two-car mainsheet
This fast-tacking two-car system halves the distance a single car would travel. The bridle and the 2:1 side-to-side traveler controls raise and lower the floating mainsheet block for perfect mainsail twist. Mainsheet tension tightens the leech and reduces twist.
