Typical Sail Inventory
What Hunter 15 owners usually carry and what's worth buying used vs. new.
Mainsail 64.9 ft²
Dacron cross-cut with 2 reef points is standard. Full-batten is a common upgrade.
Replace new
150% Genoa 41.2 ft²

Buy used
Storm Jib 13.7 ft²
Bright orange recommended. Rarely used, hard to justify new.
Buy used
Asymmetric Spinnaker ~99 ft²
Popular downwind upgrade — easier than symmetric for shorthanded sailing.
