Jeanneau TH38 signals bold entry into compact power catamarans

Jeanneau’s TH38 is landing as more than another new hull in the outboard cat lane. The boat marks a serious push into compact power catamarans, with Jeanneau using the TH range to show how much comfort, stability and family-friendly versatility can now fit into a 38-foot package.

The design split is clear. Marc Lombard Yacht Design Group drew the hull lines, while Garroni Design shaped the interior and deck ergonomics, and the result is built around usable space rather than the old idea of a tight little dayboat. Jeanneau says the TH38 carries a beam of 4.45 metres, a deck area of more than 15 square metres and room for up to 15 people. That scale matters because it gives the boat the feel of a floating social platform, not just a fast commuter with seats bolted on.

The outdoor plan is the headline feature. Convertible cockpit benches can shift the space from dining area to sunpad to lounge, and the hardtop adds shelter without shutting down visibility. The bow is treated as a real living area too, opening up as a lounge that can stay exposed or be shaded for anchoring, sunset drinks or long day-use runs. Jeanneau also offers two windscreen choices, a full-height version and a low-profile version, which lets owners push the boat toward either protection or a more open profile.

That layout is what makes the TH38 feel like a category-expanding move. The boat is not being sold as a stripped-back day machine. BoatTEST lists twin identical air-conditioned cabins, and Jeanneau’s own materials say the structure creates two large twin cabins with private heads and separate shower stalls. In a 38-footer, that is a direct challenge to the assumption that overnight comfort has to give way to deck space.

Power-cat buyers have been moving toward exactly this mix of features, and Jeanneau is leaning into that shift with a model launched in December 2025 and shown as part of its broader power-cat push. The range is backed by nearly 70 years of heritage and more than 400 sales points, which gives the TH38 a mainstream reach many niche multihulls never get. Multihulls World lists twin 300/350 hp outboards, while BoatTEST gives the boat an LOA of 38 feet 9 inches, fuel capacity of 246 gallons and water capacity of 50 gallons. The message is hard to miss: compact power cats are no longer just about novelty or day use. The TH38 is built to pull monohull cruisers and sailing-cat owners alike into a segment that now promises speed, space and real overnight usability in the same hull.
