Production began in 2006, and roughly 250 boats have been built. The Djinn 7 remains in B2 Marine’s catalogue as a larger, more spacious evolution of the earlier Blue Djinn.
Design and Construction
The Djinn 7 measures 7.18 meters long and 2.5 meters wide and carries a CE category C5 / D6 rating. Its hull is deliberately narrow, with almost vertical sides that keep it within road-trailer width limits. An almost straight bow extends the waterline to improve performance.
A quarter brie daggerboard made of galvanised steel and a pivoting rudder cut from aluminium sheet define the underwater profile. Together, they provide reduced draught and easy transport. The Djinn 7 can also dry out flat in just 30 centimeters of water.
B2 Marine builds both the hull and deck from solid fiberglass. Construction relies on simple, proven solutions: glitter paint stands in for traditional crockery, and the builder says everything aboard is easy to replace without significant expense. The finishes are plain but age well, suiting a boat intended for regular family use rather than show.
Rig, Performance, and Handling
The Djinn 7 carries a fractional sloop rig with a furling genoa and no backstay. This arrangement keeps the rig simple, but it also shapes the boat’s sailing characteristics.
The wide waterline beam provides good form stability, and the boat accelerates eagerly once filled in, particularly with a gennaker set. Upwind, however, the basic anti-drift plan leaves it wanting. The absence of a backstay also means it quickly stumbles into the downwind guying.
Some owners have added homemade backstays, while the most recent models occasionally carry a horned mainsail. Even so, period reviews describe the rig as difficult to optimize. The boat remains well-mannered in a breeze, but in 25 to 30 knots downwind, it’s better to ease off.
Its shallow draught and centerboard are particularly well suited to tidal and shallow waters.
Cockpit and Accommodations
Below deck, the Djinn 7 does without partitions to maximize interior volume. It sleeps six, including a full-width double berth beneath the cockpit—a notable achievement in a 7-meter hull.
The fittings are simplified to the extreme, but they meet the basic needs of family cruising. Most stowage is beneath the berths, while the galley and chart table are symbolic rather than functional. When raised, the aluminium daggerboard passes through the saloon table.
In the cockpit, the mainsail turret doubles as the base for an outside table. The transom carries both the outboard and rudder but leaves a gap for swimming or stepping ashore onto sand.
Taken together, the layout makes the Djinn 7 a liveaboard-capable pocket cruiser built around space and simplicity rather than refinement.
Known Issues and Trade-Offs
Reviewers note that the gangways are narrow and that the lower shrouds obstruct passage forward. The rig is also difficult to tune, while the boat lacks drive both upwind and downwind. The same assessments suggest that a better-studied rig and wider rear skirt would improve matters.
These shortcomings are inherent trade-offs in the no-backstay, volume-maximized layout rather than defects in build quality.
Refits and Ownership
Ownership is relatively straightforward. B2 Marine’s simple construction makes components cheap and easy to replace, while the boat’s transportable design allows an owner to trail it home for maintenance.
The Djinn 7 Confort variant has the same dimensions and CE rating but offers the factory’s plusher trim. Because the design remains in the builder’s catalogue, new and used boats share a common parts lineage.
The Verdict
The Djinn 7 is a pragmatic, trailable family cruiser. It trades upwind bite and rig sophistication for interior volume, shallow-water freedom, and inexpensive upkeep. It best suits sailors who value beaching, simple systems, and six-berth capacity in a package that can be towed behind a car.
Pros
- Dries out flat in 30 cm of water and is easy to trail
- Six berths, including a full-width aft double, in a 7.18 m hull
- Simple, low-cost components that are easy to replace
Cons
- Basic anti-drift plan limits performance upwind and downwind
- Narrow gangways and lower shrouds that obstruct passage forward
- Rigging is difficult to optimize without owner modifications
