Typical Sail Inventory
What Ct 54 owners usually carry and what's worth buying used vs. new.

150% Genoa 1,080.0 ft²
The workhorse headsail. Most boats have one on a furler by now.
Replace new
110% Working Jib ~792 ft²
Good secondary sail for breezy days — used market is strong.
Buy used
Storm Jib 360.0 ft²
Bright orange recommended. Rarely used, hard to justify new.
Buy used
Asymmetric Spinnaker ~2,592 ft²
