Lotus 25 Information, Review, Specs

Sailing Performance & Handling

The Lotus 25 is characterized by a moderate displacement hull and a traditional masthead sloop rig. Unlike many modern boats of this size that utilize a lightweight spade rudder, the Lotus 25 features a skeg-hung rudder. This design choice, favored by Bigoin, enhances directional stability and protects the rudder from debris, though it makes the boat slightly less "snappy" in tacks compared to a racing dinghy.

On the water, the boat is known for its predictable behavior. With a displacement-to-length ratio that leans toward the heavier side of the "light cruiser" spectrum, it carries its momentum well through a chop. Owners often report that the boat feels "bigger" than its 25-foot length, a trait attributed to its generous beam and relatively high freeboard. Under sail, the Lotus 25 performs best in a stiff breeze; while it may struggle in very light air due to its wetted surface area, it remains stiff and upright when the wind picks up, reducing the need for early reefing. The balance between the fin keel and the sail plan ensures that helm pressure remains manageable even when pressed.

Interior Comfort & Variations

For a vessel of its era and size, the interior of the Lotus 25 is remarkably utilitarian. The layout typically features a traditional V-berth forward, separated from the main saloon by a small hanging locker and a compact head (toilet) compartment. The main saloon consists of two facing settees with a central folding table, which can often be converted into additional berths.

The galley is positioned near the companionway for optimal ventilation, usually equipped with a two-burner stove and a modest sink. Headroom is approximately 1.75 meters (5'9"), which was generous for a 25-footer in 1972 but may feel cramped for taller modern sailors. CNSO utilized a significant amount of molded fiberglass liners (inner skins) which, while making the interior easy to clean and bright, limits the ability to access the hull-to-deck joint in some areas. The Lotus 750 variant is essentially identical in hull form, though some later models featured updated wood trim and revised window profiles to modernize the aesthetic.

Known Issues & Buyer’s Checklist

Prospective buyers should approach a Lotus 25 with the understanding that these vessels are now over 50 years old. While the hulls are over-engineered by modern standards, specific technical areas require scrutiny:

• Osmosis: Like many early French fiberglass boats from the 1970s, the Lotus 25 is prone to osmotic blistering. A professional moisture meter test on the hull below the waterline is essential, especially if the boat has been kept in the water year-round.
• Deck Core Integrity: CNSO used a balsa or plywood core in certain deck sections. Buyers should walk the side decks and foredeck specifically looking for "soft spots" or "deflection," which indicate water ingress around stanchion bases or cleat mounts.
• Chainplates and Rigging: The stainless steel chainplates are bolted through the hull. Over time, leaks at the deck level can cause crevice corrosion. These should be inspected for rust streaks or signs of movement.
• Mast Step Compression: The mast is deck-stepped. It is vital to check the structural bulkhead inside the cabin directly beneath the mast for signs of compression or cracking, which can occur if the support post has settled over decades of rig tension.

Community & Resources

While there is no longer a dedicated factory presence for CNSO, owners of the Lotus 25 often find technical support through the broader French sailing community. The most prominent resource is the Club des Amis Propriétaires de Karaté, which, while focused on the Karate model, often serves as a repository for technical knowledge regarding CNSO construction methods and Bigoin's design nuances. Information on the Lotus 25 can also be found through the archives of the Association des Propriétaires de CNSO, a group dedicated to preserving the history of the Bon-Encontre shipyard.

The Verdict

The Lotus 25 is a robust, "honest" cruiser that offers a high degree of safety for those venturing into coastal passages. It lacks the speed of a modern sportboat but compensates with a solid feel and a forgiving nature.

Pros:

• Structural Integrity: Hand-laid fiberglass hull is significantly thicker than modern production equivalents.
• Seaworthiness: Skeg-hung rudder and stable hull form provide confidence in heavy weather.
• Affordability: Represents one of the most cost-effective ways to enter the world of overnight cruising.

Cons:

• Age-Related Maintenance: Buyers must be prepared to address 50-year-old plumbing, wiring, and potential osmosis.
• Light Air Performance: The boat's weight and hull shape make it sluggish in winds under 8 knots.
• Limited Headroom: Taller sailors will find the cabin height restrictive for extended stays.
