Typical Sail Inventory
What X 119 owners usually carry and what's worth buying used vs. new.
Mainsail 451.5 ft²

150% Genoa 513.9 ft²
The workhorse headsail. Most boats have one on a furler by now.
Replace new
110% Working Jib ~377 ft²

Buy used
Storm Jib 171.3 ft²
Bright orange recommended. Rarely used, hard to justify new.
Buy used
Asymmetric Spinnaker ~1,233 ft²
