All-Purpose | Sailors +90Kg
The new F-4 Mainsail is designed for the Solo sailors from 90kg upwards. The F-4 is fuller and more powerful than the P-4 design and this updated design allows for more forgiving trim than previous full cut sails.
The F-4 complements a wide range of mast sections (Cumulus | Zeta | D | M2 | M7 | C Sleeved).
