About the Pacific 4245

Relatively little documentation has survived about the Pacific 4245, making it something of an elusive entry in the sailboat record books. What can be inferred from its name suggests a mid-sized cruising vessel likely designed with Pacific coastal or bluewater passage-making in mind, built for sailors who prioritize capable, comfortable offshore performance over racing podiums. Boats from this era and region of production were typically crafted with an emphasis on seaworthiness and practical cruising amenities, offering a stable platform suited to extended voyages and liveaboard lifestyles. If you are researching this model as a potential purchase, it is worth seeking out owner communities and archived sailing forums, where firsthand accounts often fill in the gaps that official records leave behind. Hull condition, rigging history, and interior layout are likely to vary between examples given the age of most surviving boats. For the patient buyer willing to do thorough due diligence, lesser-documented cruising sailboats like the Pacific 4245 can represent genuine value, provided a qualified marine surveyor inspects the vessel before any purchase commitment is made.

Performance Ratios
SA/Displacement Sail Area to Displacement ratio measures how much sail power a boat has relative to its weight. Higher values mean more performance and speed.
Under 14 — Heavy cruiser, slow14–18 — Cruising sailboat18–22 — Cruiser/racerOver 22 — Performance racer
15.7
Comfort Ratio Ted Brewer's Comfort Ratio predicts how comfortable a boat will feel in offshore conditions. Higher values mean a steadier, more comfortable motion in a seaway.
Under 20 — Uncomfortably rough20–30 — Acceptable coastal30–40 — Good offshore comfortOver 40 — Very comfortable offshore
40.99
Capsize Screening Formula The USHS Capsize Screening Formula estimates offshore capsize risk. Lower is safer — values under 2.0 are considered acceptable for offshore sailing.
Under 2.0 — Safe for offshore2.0–2.2 — Borderline offshoreOver 2.2 — Coastal use recommended
1.67
Hull Speed Hull Speed is the theoretical maximum speed of a displacement hull, calculated from waterline length. Most cruising sailboats reach this speed in moderate conditions. 7.89
Pounds/Inch Immersion Pounds per Inch Immersion (PPI) tells you how much weight is needed to sink the boat one inch. Useful for calculating how additional gear and stores affect waterline. 1.0
