db-22

Sportboat

Performance and design

"The new db-22 is a true performance sport boat. The sporty lines keep their promise and give the boat already at a very slight breeze an incomparable feeling af almost weightless gliding" 

Fun and fast sailling

"This boat introduces a new dimension of fun and fast sailling in a stable and easy to handle boat"

Plywood and epoxy

"The hull for the db-22 is made in epoxy treated marine plywood. This material composition ensures a strong and long-lasting hull.

In less than 300 hours

"the hull is specially designed for home building by non professional, and the accurate CNC machined plywood parts ensure a fast and easy construction process"

A kit or the drawing package

The boat can be built from a ready-made kit or you can buy a digital drawing package and make the kit yourself.

Do you have the skills

To understand the construction and building method, you can start by building a scale model.

It all starts with a stack of sheets

With all the parts cut out an ready to assembly

The large hull panels that cannot be within the standard format (122x244 cm) are divided into smaller pieces. The panels are assembled with "puzzle joints". these joints are later reinforced with fiberglass.

Each and every joint is made with a mixture of epoxy and filler.

Chine joints are additionally reinforced with fiberglass tape.

All internal surfaces are sealed with 2-3 layers of epoxy.



All the parts are designed to tap together, making it almost impossible to assemble incorrectly

External surfaces are laminated with a layer of 280 gram/m2 fiberglass rowing. this adds strength and robustness to the hull, but most importantly, it seals the plywood against moisture.


A proper surface treatment with epoxy and polyurethane topcoat, gives a strong, light and long-lasting hull.


A boatkit or the drawing package

a ready-made or a do-it-yourself solution

Digital Drawing Package

Our digital drawing package contains CAD data on all individual parts that are needed for you to manufacture a hull construction kit yourself.

drawings on special parts such as chainplates etc. is also included.


All individual parts are nested on 9 and 12 mm "plywood sheets", We use the standard format 1220x2440 mm.
So all you need is to buy some quality marine plywood sheets, and to  find a manufacturer who is able to cut the parts either with a milling machine or with a laser.

We use the following formats: DXF, DWG and PDF.


A detailed construction manual is included, here we guide you through the steps of the construction process, how the parts are glued together, surface treatment, choice of epoxy and fiberglass and of course all our tricks.


Being able to see the boat virtually in 3D is often a great help, which is why we have included a 3D model. The model can be viewed in the free program "e-drawing" In this program it is possible to measure, make cut views, and to "click" the various pars on and off, to see the construction behind.


Plans included:

  • Hull assembly 
  • Deck layout
  • Keel plan
  • Rudder plan
  • Sail and rig plan


Buying the Digital Pacakage, include a license to build one boat.


Our digital package is the obvious choice if you don't live near Denmark. Overseas shipping is expensive and not environmentally friendly.

Plywood hull kit

Get started quickly with a complete wooden db-22 hull kit, here everything is cut out and ready to assemble.


Our db-22 kit comes in a pack consisting of: 12 sheets of 9 mm plywood and 11 sheets of 12 mm plywood.

In total, the kit consists of 141 individual plywood parts and 9 stainless steel parts (chainplates). 


For our building kits we use only the best quality Okume/Gaboon marine plywood.


As with our digital drawing package, detailed construction manual and a 3D "e-drawing" model are included.


Plans included:

  • Hull assembly
  • Deck layout
  • Keel plan
  • Rudder plan
  • Sail and rig plan


Buying the Plywood hull kit, include a license to build one boat.



What about all the rest ?

more than the hull is needed before you are ready to sail

Keel and rudder

Buildaboat are able to deliver a complete ready-made keel and rudder.

the keel shaft is molded in fiberglass and the torpedo is in lead. The rudder blade is also molded in fiberglass.

Keel blade and rudder blade are both molded using  vacuum infused technology.


Are you more interested in making the keel and rudder yourself? We have made a package with drawings, cut-files and descriptions of how you can make these parts yourself in plywood/glass fiber and epoxy.


The keel torpedo must be sand cast in lead. our drawing package contains, drawings and descriptions of how you can make the plug used for this process.


Please find the keel and rudder options in our shop



Mast, rigging and sails

We are happy to supply the mast and sails for your db-22.


We sell masts and rigging from Z-Spars / Hansen Harmacher and sails from Ullman Sails.

Understand the construction

Pratice by building the study model

Study model

We have produced a scaled-down version of the db-22 hull, which we call the study model.


The model is a 13% scale of the boat and contains most of the parts included in the real hull.


With this model, you get an understanding of the order in which and how the various parts are put together.


Are you curious about the construction and would you like to learn more about the assembly method etc. then the Study model is a good place to start your boat building career.


You will find the study model in our Webshop.
