The Jeanneau Tonic 23 CB is a compact yet capable sailboat, designed to offer a lively sailing experience coupled with surprising interior volume for its size. Conceived as a versatile coastal cruiser and trailer sailer, it quickly gained a reputation for its ease of handling and its ability to access shallow waters thanks to its clever centerboard design. This French-built monohull, launched in 1985 by the renowned shipyard Jeanneau, was the brainchild of celebrated French maritime architect Philippe Harlé.

The story of the Tonic 23 CB begins in 1985, a period when Jeanneau, under the ownership of Bangor Punta, was already a firmly established name in sailboat manufacturing, known for embracing new technologies like fiberglass construction and mass production techniques. During this era, Jeanneau was cultivating its identity through collaborations with distinguished naval architects, focusing on "liveable boats" that blended performance with onboard comfort. Philippe Harlé, the designer of the Tonic 23 CB, was known for choosing "slightly more spacy hull designs". The Tonic 23 CB embodies this philosophy, aiming to provide enjoyment and a unique experience on the water. While the boat was available in both fixed keel and centerboard (CB) versions, the centerboard variant, like the Tonic 23 CB, offered the added flexibility of a minimal draft for beaching.

Sailing Performance and Handling

Measuring just under 24 feet overall with a waterline length of 20.33 feet, the Jeanneau Tonic 23 CB is designed for agile and responsive sailing. With a displacement of 2926 pounds and a ballast of 1086 pounds, it possesses a solid, yet sprightly character for a boat of its dimensions. Its fractional sloop rig, with a reported sail area of 248 square feet, contributes to its "lively sailing performance" and its ability to be "fast through the water".

The centerboard keel, which allows the draft to be reduced from a maximum of 4.5 feet to a minimum of 2.25 feet, is a key feature enhancing its versatility, particularly for exploring shallow anchorages or for trailering. Anecdotal evidence suggests the boat sails "crisply and easily handled single". However, some owners have noted that the boat "does not sail to windward well" in certain conditions. Its theoretical hull speed is estimated at 6.04 knots.

Accommodations and Layout

Despite its modest length, the Jeanneau Tonic 23 CB offers a surprisingly spacious interior, capable of comfortably accommodating four adults. The designer, Philippe Harlé, is noted for creating a "slightly more spacy hull design," which translates into usable interior volume. While specific headroom figures are not consistently available, the layout is generally described as simple and unobstructed.

Typical interior arrangements for boats of this size often include a forward V-berth, a small galley area, a compact head compartment, and a main salon with settees that can serve as additional berths. The boat's 5-gallon water capacity suggests basic onboard amenities. Owners' manuals indicate a standard electrical circuit and bilge pump system. The overall finish and materials, consistent with Jeanneau's production values of the era, would typically feature a combination of molded fiberglass and functional, durable finishes, designed for practicality and ease of maintenance in a compact cruising environment.

Owner's Perspectives

Owners of the Jeanneau Tonic 23 CB generally praise its solid construction and its "lively sailing performance" for a boat of its size. Its centerboard feature is highly valued for allowing access to shallower waters and simplifying trailering and beaching. The boat is often described as easy to handle, even for single-handed sailing. Common discussions among owners revolve around optimizing outboard engine setups, particularly for reducing drag when sailing. While many find its performance commendable, some owners have observed limitations, such as its performance to windward in certain sea states or stronger conditions. The active owner community often shares insights on maintenance, such as managing the centerboard housing.
