ti segnalo i 2 code0:


1 x Fractional Code 0 ("FRO")
Sail area: 235 m²,
Material: 3Di, RAW760 yellow, 16800 dpi
Details: Hoisted to the hounds.
Use: The FRO is a downwind sail used in fresh breeze (when the A3 becomes too big) and for reaching (when the MHO is too big). It will likely be used upwind in light breeze too.

1 x Masthead Code 0 ("MHO")
Sail area: 305 m²
Material: 3Di, RAW760 yellow, 13600 dpi
Details: ---
Use: The MHO is a light wind sail (0-6 knots). It is also used when reaching in moderate conditions and downwind in strong breeze.
