Typical Sail Inventory
What Dynamique 52 owners usually carry and what's worth buying used vs. new.

Dacron cross-cut with 2 reef points is standard. Full-batten is a common upgrade.
Replace new
150% Genoa 677.9 ft²
The workhorse headsail. Most boats have one on a furler by now.
Replace new
110% Working Jib ~497 ft²
Good secondary sail for breezy days — used market is strong.
Buy used
Storm Jib 226.0 ft²
Bright orange recommended. Rarely used, hard to justify new.
Buy used
Asymmetric Spinnaker ~1,627 ft²
Popular downwind upgrade — easier than symmetric for shorthanded sailing.
