F18

Class History

The Formula 18 fleet is one of the fastest growing in the world. Electrifyingly quick, these double-handed, twin-trapeze and technically-exciting speed machines are designed to a box rule that allows a variety of builders to manufacture similar boats with similar performance. Fair racing is insured for male, female, and mixed crews by using corrector weights and two sizes of jibs and spinnakers. F18-sailplan.gif

Crossbow Pivoting Self-Tacking Jib System

This self-tacking jib system features a curved track that hinges to align both car and track with the sheet loads for less friction, more load-bearing capacity, and a lighter-weight design.

Spinnaker Sheet System

Four 57 mm Carbo Ratchamatic blocks make up this powerful system—two ratchets per side double the sheet holding power. Ratchet mechanism automatically engages/disengages as loads increase or decrease.

Cunningham

396The 16:1 cunningham system is the gas pedal on these boats. Contained in a compact package at the base of the spar, crew can power and depower the main from the trapeze.

10:1 Mainsheet

10:1 Carbo mainsheetThe 57 mm Carbo 5-sheave, HC7668 block and HC8454 provide the muscle for this 10:1 low-profile mainsheet system. Sheaves roll freely in both directions under low loads. Ratchet makes it easy to hold and ease loaded lines.
