Performance Ratios
How the Pacific 30 carries its sail relative to its displacement.
SA/D Ratio
11.7
Heavy and modestly canvassed — a comfortable cruiser, not fast.
Mast Height (above DWL)
41.0 ft
Clears the 65 ft ICW fixed-bridge standard with room to spare.
Ballast Ratio
43%
Stiff enough to carry a 150% genoa comfortably into moderate breeze.
Typical Sail Inventory
What Pacific 30 owners usually carry and what's worth buying used vs. new.
Mainsail 168.8 ft²
Dacron cross-cut with 2 reef points is standard. Full-batten is a common upgrade.
Replace new
150% Genoa 231.0 ft²
The workhorse headsail. Most boats have one on a furler by now.
Replace new
110% Working Jib ~169 ft²
Good secondary sail for breezy days — used market is strong.
Buy used
Storm Jib 77.0 ft²
Bright orange recommended. Rarely used, hard to justify new.
Buy used
Asymmetric Spinnaker ~554 ft²
Popular downwind upgrade — easier than symmetric for shorthanded sailing.
