Initial watering DIAMANT**

In the middle of the dewatering season we have launched and rigged our world premiere DIAMANT** for the first test sailings. Interested people are welcome to view the boat.

Dewatering season

During the next 4 weeks, we have 70 boats to take out of the water and to bring in full service into our our shipyard's winter storage. Afterwards we'll go ahead with shipyard orders such as osmosis treatments, GRP repairs and flexiteek laying.


World premiere

At the upcoming Interboot, we will be presenting our new DIAMANT** as part of a world premiere. We will be happy to show you our new Daysailor in the 7.5 metre class at our stand in hall A3, stand 100/6 (next to our APHTODITE IOI).

There are minor changes regarding deck and cabin, the boat is equipped with a single-spreader rig without any type of backstays, with a self-tacking jib, fat-head mainsail as well as a large aft-open cockpit. Simple and fast sailing with very easy handling was the main focus. The start price for a ready-to-sail boat is 54 thsd eur. Length 7.35m, width 2.50m, draught 1.25m, easily trailerable as just 1,100kg weight, mainsail 20m², self-tacking jib 9m², gennaker 56m².
