The Jongert 31T ALME SOL is a true masterpiece — the final yacht of the renowned Dutch shipyard’s classic line. As such, she represents the culmination of over two generations of yacht-building excellence at Jongert.
Launched in 2005, this elegant Jongert 31T is ideally suited for world cruising and swift ocean crossings. ALME SOL perfectly embodies the balance between luxurious comfort, superior craftsmanship, and impressive sailing performance.
Constructed in steel with an aluminium superstructure, she features hydraulically furling sails for effortless handling. Her Jongert-patented folding keel reduces draft from 4.50 m to 2.50 m, offering outstanding performance under sail while allowing access to shallow anchorages and harbours.
On deck, the raised helm position aft of the deckhouse provides excellent visibility, while the light-filled deck saloonwith panoramic views ensures comfort and protection in cooler climates. Expansive deck areas invite sunbathing and relaxation, and the spacious cockpit is perfect for al fresco dining and entertaining.
Below deck, ALME SOL reveals the timeless elegance of a traditional Jongert interior, crafted in rich mahogany. The spacious lower saloon with dining area connects to the guest quarters aft, comprising a full-beam owner’s cabin, VIP cabin, double cabin, and twin cabin, all en-suite. Forward, and completely separate, the crew area includes two en-suite cabins, a galley, and a crew mess with private deck access and direct entry to the engine room.
ALME SOL is a safe, reliable, and beautifully maintained family yacht, primarily cruised in the Mediterranean and always kept in exceptional condition. Now in second ownership, she stands as one of the most comprehensively specified and best-preserved examples of the Jongert 31T series — a true jewel among classics.

INSULATION
_________________
Thermal Insulation: all surfaces adjoining the open air, from 10cm under the waterline to the deck, including super structure, received a polyurethane insulation up to 30mm.
Special attention was given to reduce the noise & vibrations transmission on board.
A viscoelastic damping treatment was made on top and on the sides of the engine room bulkheads, as well as the propeller shaft area and aft of waterline. The interior of the engine room is covered with mineral wool, followed by a sound damping sandwich metal plate. Against the hull there will be a layer of mineral wool covered with firet cloth and a perforated plate.
Additionally, the outside of the engine room bulkheads as well as the top is covered with mineral wool.
In-between the owner’s and guest cabins “multi-Sandwich” bulkheads with integrated lead layers were installed to achieve a maximum noise level of 65dB(A) with the main engine running at 1.500rpm.
Furthermore, the complete interior is “floating” for maximum noise reduction.
