Harken International 470 Deck Layout

International 470

"Many 470 teams fit out their own boats and personalize their systems, so there are 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."Mitja Margon - Managing Director Harken Slovenia; Olympic classes specialist.

Spinnaker Pump Halyard System
A 1:2 reverse purchase on the halyard allows the skipper to raise the spinnaker fast??pulling the pump handle .6 m (2 ft) off the cockpit floor raises the spinnaker 1.2 m (4 ft). A 1:5 shock-cord halyard take-up system automatically manages accumulating line during the rapid chute deployment.

Vang
The cascaded vang uses super strong single, double, and triple 16 mm blocks for 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.

CLASS HISTORY
The International 470, designed in 1963 by 505 sailor André Cornu, is a high-performance planing dinghy for both men and women. Responsive to weight placement, this two-person one-design is tactically demanding and requires fluid coordination between the skipper and crew. The 470 is easy to sail, but racing and flying the spinnaker from the trapeze provides additional challenges for sailors. The 470 made its Olympic debut in 1976, and in 1988 was selected for the Games first women's sailing event. The 470 continues to shine with its selection by the ISAF as the two-person dinghy-men and two-person dinghy-women for the 2016 Games in Rio de Janeiro, Brazil.
