Design and Construction
Boo Marin built the Aphrodite 25 in fiberglass with a solid hull, and the yard offered the boat with different keel alternatives. One option is a fin keel cast in lead; another is a fin keel made of iron, both drawing about 4.9 to 5.2 feet depending on load. The 41 percent ballast ratio and 2.67 length-to-beam ratio describe a narrow, ballast-heavy little hull, while the displacement-length ratio of 194 categorizes her among "moderate racers" rather than out-and-out lead-mines. Her wetted surface runs about 236 square feet, a modest footprint for the size that keeps her responsive without demanding a large rig to drive her.
Rig and Handling
The Aphrodite 25 carries a fractional sloop rig, and the standing and running dimensions are thoroughly documented. Halyards for the main, jib, and spinnaker each run 79.7 feet at 5/16 inch diameter, while sheets scale with the sail they control: the mainsheet is 62.3 feet of 3/8 inch line, genoa and jib sheets 24.9 feet of the same diameter, and the spinnaker sheet 54.9 feet. Control lines follow suit, with a 9.5-foot cunningham and 19-foot kicking strap and clew outhaul all at 5/16 inch. Under the ISO 8666 reference sail the sail-area-to-displacement ratio is 15.4, rising to 18.0 with a 135 percent genoa — a meaningful jump that tells you the boat was meant to be sailed with overlapping headsails to wake her up.
Performance Profile
The theoretical hull speed of a displacement hull this length is 6.2 knots, yet the calculated maximum under the Volvo Penta MD5 engine is only about 4.2 knots, so propulsion is strictly auxiliary. The Motion Comfort Ratio falls between 13.7 and 16.7, and the capsize screening value is 2.21 — a figure that would bar her from ocean racing under the standard rule. The Relative Speed Performance index sits at 79, and the immersion rate of about 705 pounds per inch means she settles noticeably under crew and gear for a boat of her size.
Known Issues
The boat was delivered with either lead or iron fin keels, and the iron version carries the well-understood caveat that ferrous ballast needs vigilance against corrosion at the hull joint over a decades-long service life.
The Verdict
The Aphrodite 25 is a tidy, limited-production Scandinavian design that rewards a sailor wanting a light, easily driven 25-footer with documented rig dimensions and a clear performance envelope. She is not an offshore boat by the numbers, but as a coastal cruiser-racer with a fractional rig and a choice of keel metals she offers a coherent, well-defined package.
Pros
- Fractional sloop rig with fully documented line sizes and lengths
- Choice of lead or iron fin keel, both with shoal-enough draft for most marinas
- Moderate-racer displacement profile with a 41 percent ballast ratio
Cons
- Capsize screening value of 2.21 excludes her from ocean racing
- Engine top speed of only 4.2 knots under the MD5
