Sailing experience
The speed flexibility of the 3900MY is the most striking feature of this new Jongert yacht. ‘You go smoothly from full displacement to gliding across the water. Remarkable is also the fact that with a draught of two meters the yacht effortlessly achieves its top speed without first drawing its back deeply into the water. The master can choose from an unlimited range of speeds. Many gliders and half gliders have a relatively large speed range where you are as they say “climbing the mountain” causing unpleasant heavy stern waves and high fuel consumption.

The 3900MY is the first motor yacht of these dimensions ever built by Jongert. Much attention has been paid to comfort during the design of the yacht. The motor yacht line has been developed by the yard at the specific request of several customers who appreciate the design of the Jongert sailing yachts but prefer a motor yacht.
