The 2900M is one of the most fascinating in a long line of semi-custom yachts from JONGERT. Essentially, the 29m aluminium Jongert/ Castro hull is standard, while the rig, deck layout and accommodation are tailored to individual owner’s requirements.
Built for an experienced sailor who had already owned JONGERT yachts, MBOLO combines an easily-driven hull capable of reaching speeds up to 13.5 knots with spacious accommodation and on-deck amenities worthy of a luxury penthouse. In the process, JONGERT have come up with a design that is both modern-looking and yet easy on the eye. Ideally suited to light weather sailing, she is capable of accelerating fast without being uncomfortable!
This is a sophisticated yacht capable of being managed with a minimum of crew. In fact, the skipper and a single deckhand are all the help that’s needed while cruising with the owner on board. A total of three can easily manage the boat on longer passages and deliveries.
The cutter rig also gives a greater choice of sail combinations and is particularly useful in windy weather when the boat can be steadied by just setting the staysail and reefed main. The fully-battened main makes for ease of handling too, while the bow- and stern thrusters make manoeuvring in a harbour very easy.
The wheelhouse roof, a sleek and purposeful-looking structure was built to withstand everything the ocean can throw at it. When the sun is shining, however, the whole thing slides away to reveal a comfortable sitting area – ideal for those lazy summer lunches.
Likewise the ‘well’ on the foredeck which, while on passage, provides a safe, unobtrusive stowage for the tender. Pop the dinghy in the water, fill the well with water, and you’ve got a built-in Jacuzzi with the best views in the world! Further aft, the transom opens up at the press of a button to reveal a bathing platform, as well as further stowage for a diving compressor, surfboards and other toys.
Pear wood finish throughout.

The vessel is in excellent condition and was refitted in 2010 and 2011 at the Jongert shipyard. The keel was changed in the Jongert Shipyard in 2005 as the owner wanted to increase the performance. Also this keel construction was completely checked and proven by Lloyds and was part of the full hull Lloyd’s certification. She was designed to be a cruiser with an excellent performance and can be handled with small crew. One of the fantastic features is that she performs very well in light winds but does not heal too much in heavy seas.
