Reference > Spinnaker

A well-designed spinnaker system makes setting, flying and jibing the chute easier, and your boat faster.

Typical boat length:
Small Boat: 22' - 28' (6.7 - 8.5 m)
Midrange: 29' - 34' (8.8 - 10.4m)
Big Boat: 35' - 42' (10.7 - 12.8m)

1. Masthead rigs to 28' (8.3 m) and fractional rigs to 32' (9.7 m) use a simple arrangement with one pair of sheets. The windward sheet becomes the guy. During jibes the pole is disconnected from the mast and passed end-for-end through the foretri-angle. Tweakers are used to bring the guy to the deck near the point of maximum beam to increase control over the pole. A single line foreguy is appropriate for these boats.

2. Offshore boats over 30' (9 m) use separate sheets and guys. The sheets lead to turning blocks at the transom while the guys lead to blocks at the point of maximum beam. While the windward guy is in use, the sheet on that side of the boat is "lazy." A double-ended foreguy facilitates adjustment from either side of the boat.

3. Boats with asymmetrical spinnakers and retractable bowsprits are rigged with a tack line leading through a block on the end of the sprit and aft to a cleat or stopper. There are two sheets attached to the clew of the sail. The lazy sheet leads ahead of the headstay, over the sprit, and aft outside the shrouds and sheets.
