Mast Height (above DWL)
69.0 ft
Tight on the 65 ft ICW standard — check tide before transiting.
Ballast Ratio
41%
Stiff enough to carry a 150% genoa comfortably into moderate breeze.
Typical Sail Inventory
What Cs 44 owners usually carry and what's worth buying used vs. new.
Mainsail 481.0 ft²
Dacron cross-cut with 2 reef points is standard. Full-batten is a common upgrade.
Replace new
150% Genoa 733.8 ft²
The workhorse headsail. Most boats have one on a furler by now.
Replace new
110% Working Jib ~538 ft²
Good secondary sail for breezy days — used market is strong.
Buy used
Storm Jib 244.6 ft²
Bright orange recommended. Rarely used, hard to justify new.
Buy used
Asymmetric Spinnaker ~1,761 ft²
Popular downwind upgrade — easier than symmetric for shorthanded sailing.
