A compact and accessible daysailer, the Neptune 16 is designed with simplicity and ease of use in mind, making it a natural fit for beginner sailors and those seeking relaxed coastal sailing experiences. Built to handle sheltered waters, lakes, and calm coastal environments, this small keelboat offers a stable and forgiving platform for learning the fundamentals of sailing or enjoying leisurely outings without the complexity of a larger vessel.
While detailed specifications for the Neptune 16 are limited, its modest size suggests a boat that prioritizes approachability over performance ambition. Boats in this class typically reward sailors who value ease of trailering, low maintenance, and straightforward rigging — qualities that make weekend sailing genuinely enjoyable rather than a logistical challenge.
The Neptune 16 may appeal particularly to families, newcomers to the sport, or experienced sailors looking for a simple, low-cost second boat. Though it lacks the offshore capability or racing pedigree of larger designs, its charm lies in its unpretentious character and the accessible entry point it offers into keelboat sailing.

About this estimate
Prices are based on recent asking prices from public listings — not actual sale prices, which are typically lower.
Condition is not factored in. A well-maintained boat with new sails and engine can be worth significantly more than a project boat of the same model.
Location affects price. Boats in landlocked states or areas with fewer buyers often sell for less than those on the coast.
Year of manufacture is not filtered. Older examples of this model will generally be priced lower than newer ones.
Included equipment varies widely. A boat with a full suite of electronics, dodger, and new standing rigging may command a large premium.
Outliers are automatically excluded using statistical filtering to improve accuracy, but some bad data may remain.
PHRF Rating
PHRF (Performance Handicap Racing Fleet) is a national racing handicap measured in seconds per nautical mile. Lower values indicate faster boats. Ratings are sourced from US Sailing's national database (median across 60+ regional fleets).
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
19.77
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
8.68
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
2.56
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.
4.92
S# (Speed Number)
The Speed Number (S#) is a quick performance index. Higher values indicate a faster, more powerful design relative to its size.
Under 3.0 — Slow cruiser3.0–5.0 — Average cruiser5.0–7.0 — Performance cruiserOver 7.0 — Racer
3.54
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.
