A unique hull for a pioneering yacht

Last week the first Dehler 34 hull with a length of 10.30 m and a width of 3.60 m has been demoulded and will now enter the assembly line of the Dehler shipyard in Greifswald, Germany.

Last week the first Dehler 34 hull with a length of 10.30 m and a width of 3.60 m has been demoulded and will now enter the assembly line of the Dehler shipyard in Greifswald, Germany. This moment represents an important milestone in the production of every newly developed yacht and was closely watched by the Dehler team.

The hull for the new Dehler 34 is, as customary for Dehler, built with a full sandwich core and differentiates itself from others with some special features. The full sandwich construction offers higher stiffness, very good insulation and is significantly lighter than yachts with other construction methods. When the sandwich construction is viewed in detail, the first layer from the outside is the so-called gel coat, which represents the shell of the hull.

The cove line of Dehler yachts is not glued on to the hull but integrated into the gelcoat, to ensure durability. The first layer behind the gelcoat , the “outer skin” of a sandwich construction, consists of fiberglass, which is processed with vinyl esters.

The advantage of vinyl ester is its osmosis resistance, which ensures a long life of the yacht. The 16mm thick sandwich core is made of balsa wood that gives optimal insulation and makes the hull as light as possible. The final layer, the "inner skin", completes the sandwich method.
Subsequently, the floor structure is installed, which distributes the forces on to the hull. Here again, Dehler differentiates itself from other series yacht producers with the Dehler Carbon Cage.

In the next step, the interior components will be installed before the deck will be connected to the hull. The new Dehler 34 will be completed just in time for the autumn boat show season.
