Multi chine info

The multi chine Quick Assemblage (QA) method was introduced in 1984. All together more than 1500 yachts are built according to this method all over the world. The secrete lies in the accurately computer developed expanded plate lay-outs and pre-fabrication of the expanded plate lay-outs together with marking lines for construction items as floors, frames, girders and longitudinals. The shell plates are laid down in a building jig without framing. In fact when assembling the shell plates together the hull shape will be created automatically.

We co-operate with specialized companies in several countries who offer steel and aluminum plate packages, with or without the necessary profiles such as angle bar, T-section, flat bar, tube and round bar.

The multi-chine quick assembly method is a very fast way of building. A simple building jig is sufficient in which to build. You start with the bottom plate. Thereafter the plates are tack welded one by one up to the top shell plates. Due to the great accuracy, a shell with fair lines is formed without frames. The plate joins are then welded. They remain in shape because there are no hard points to disturb the line.

The strengthening of the shell by welding in frames, floors, engine bed, chain plates is done later.

Unfortunately the price of steel and aluminium is quite unstable, the reason we can show you a price indication only.

The numbers between brackets (0) .. (4) as shown on the price indication sheet refer to the price category column on the list of materials to show you what will be delivered.

(0) Building jig profiles of steel, not sandblasted

(1) There are three CNC produced plate kit versions (steel sandblasted, steel sandblasted and coated with Sigmaweld MC www.sigmacoatings.com/downloads/00_7177.pdf and aluminium) with several keel versions available.

(2) Stainless steel AISI 316 or AISI 316L CNC produced plate kit as stem head / anchor fitting and chain plates for the steel version only.

(3) The profiles kit, supplied at standard lengths of 6 m or shorter.

(4) Stainless steel AISI 316 or AISI 316L profiles kit.

If the indicated price is within your expectation and if you are seriously interested to order a kit, please contact me at info@YachtCD.com . We will supply you with a time limited binding offer, eventually with shipping expenses. Please supply me with all version data and kit pakage required as shown on the price indication sheet. Note that the Dutch are very competitive with kits as we have a lot of yacht builders of steel & aluminium hulls here, able to order large amounts of steel and aluminium to a reasonable price. Recently we supplied a FORNA kit to Fremantle, Australia. The complete kit price including shipping expenses in a 20' container was cheaper than an Australian offered one.

If you wish more information regarding the building kit, please contact me again. In fact it easy to explain. The kit contains all exactly cut plates up to the smallest knee.

Even amateur builders are able to construct a multi chine hull. The assemblage of a hull is based on the fact that all parts are very well cut and shaped. Marking lines and part identifications will grant a perfect position in the hull structure. To assemble the hull a simple jig or cradle is required and will reduce the building time to 25% only, compared to the conventional building method. To speed up the collection of the parts you want to use we supply you with additional construction drawings with part identifications, a part list with part descriptions and nested plate lay-outs including all part identifications too.
