History

The 4.7 uses the same hull Bruce Kirby drew in 1970 and 71 for the original Laser, carrying a smaller rig with a softer bottom mast section. It became the standard entry rig for junior sailors through the 1990s as the class grew a formal pathway from Optimist to Laser.

Sailing Characteristics

Same hull, same feel, less power. The reduced sail area and softer mast bend suit sailors from around 35 to 55 kilograms, letting lighter crews sail the boat upright and depower easily in a breeze rather than fighting it.

Racing Context

Sailed at ILCA 4 youth events and national junior championships worldwide as the first rung on the Laser racing ladder before Radial and Standard.
