420 Square-Top Mainsail

This square-top mainsail for 420 dinghies uses a Fat Head design to give the boat a more modern profile and a different sailing feel.

The square-top cut adds more work in the upper part of the sail. It helps improve power control through twist, especially when the wind builds or when the crew needs more progressive trim.
