The Evelyn 25 represents the quintessential expression of Robert "Bob" Evelyn’s design philosophy: an ultra-light displacement boat (ULDB) that prioritized raw speed and tactical agility over heavy-weather cruising comfort. Launched during the peak of the IOR-influenced performance era in the early 1980s, the 25 was built by Formula Yachts to be a "giant killer" on the racecourse. It features a fractional rig, a high-aspect ratio keel, and a hull form that favors downwind surfing and light-air acceleration. While it offers a rudimentary interior, its soul is firmly rooted in the competitive circuit, where it continues to punch above its weight class in PHRF fleets across the East Coast.

Sailing Performance & Handling

The Evelyn 25 is defined by its displacement-to-length ratio, which is exceptionally low for its era, placing it firmly in the "sportboat" category before the term was popularized. With a displacement of approximately 2,200 to 2,500 pounds (depending on the specific build and equipment), the boat is highly sensitive to crew weight and trim. Performance data indicates that the boat is a "light-air flyer," capable of out-pointing and out-pacing much larger yachts when the breeze is under 10 knots.

Handling is characterized by a "dinghy-like" responsiveness. The deep-fin keel provides significant lift, but the narrow beam and light weight mean the boat is inherently tender. To keep the boat on its lines, the crew must be active on the rail; once the breeze exceeds 15 knots, early reefing or a heavy crew becomes mandatory to manage the righting moment. Downwind, the Evelyn 25 is a different animal; the flat aft sections allow it to plane in moderate blows, providing a visceral experience that few 25-footers of the 1980s could match.

Interior Comfort & Variations

True to its racer-cruiser designation, the interior of the Evelyn 25 is Spartan, reflecting a design that treats living quarters as an afterthought to the cockpit layout. The cabin provides shelter for a racing crew or a committed couple but lacks the standing headroom and amenities found in more cruising-oriented 25-footers like those from Catalina or Hunter.

The standard layout typically includes a V-berth forward, which is best suited for sail storage, and two long settee berths in the main cabin that double as seating. A small area for a portable toilet is usually situated between the V-berth and the main salon. Joinery is minimal, utilizing lightweight materials to keep the overall displacement low. While there were no major production variations like "shoal draft" versions, the boat’s sibling, the Evelyn 26, is often confused with the 25; however, the 25 is the more performance-pure hull, whereas the 26 offered a slightly more refined interior for those seeking a "pocket cruiser" experience.

Known Issues & Buyer’s Checklist

Prospective buyers should approach an Evelyn 25 with a focus on structural integrity, as these boats were often campaigned hard in offshore and coastal races.

  • Deck Core Integrity: Like many Formula Yachts builds from the early 80s, the balsa-cored decks are susceptible to moisture ingress. Particular attention should be paid to the area around the chainplates, stanchion bases, and the mast step.
  • The "Evelyn Smile": A common technical area for inspection is the keel-to-hull joint. High-load racing can cause a hairline crack at the leading edge of the keel (often called the "Evelyn Smile"), which may indicate a need for tightening keel bolts or reinforcing the internal grid.
  • Rudder Delamination: The high-aspect rudder blade is prone to water absorption and delamination. Owners often report the need to dry out the rudder or replace it with a modern composite blade to improve helm feel.
  • Rigging and Spreaders: Given the boat’s fractional rig and high-tension tuning, the spreader brackets and the mast-to-deck interface should be checked for stress fractures or compression damage.

Community & Resources

The legacy of Bob Evelyn’s designs is maintained by a dedicated community of performance sailors, primarily centered in the Long Island Sound and the Great Lakes. While there is no longer a formal manufacturer-backed class association, technical discussions and maintenance tips are frequently shared within regional PHRF organizations. Information on the designer’s broader impact can be found through the Mystic Seaport Museum, which archives the maritime history of the Groton and Noank areas where Formula Yachts operated.

The Verdict

The Evelyn 25 is a "purist’s" sailboat, offering high-octane performance for a fraction of the cost of modern sportboats.

Pros:

  • Exceptional light-air performance and downwind planing capability.
  • Easy to trailer and launch compared to heavier 25-footers.
  • Strong "cult" following ensures the boat holds its value among racers.

Cons:

  • Minimal interior comfort with very limited headroom and amenities.
  • Requires a high level of "active" sailing and crew coordination.
  • Age-related core issues require a thorough pre-purchase survey.
