Windward hull mockup

Now, after the 1:5 model proa proofed our general concept by amazing sail performance it’s time for something in real size!

To get an impression of what the living conditions on proasis will be we made a full size mockup of the accommodation compartment in the windward hull. In manufacturing and design, a mockup is a scale or full-size model of a design or device, used for teaching, demonstration, design evaluation, promotion, and other purposes. It is probably best known from the automotive industry for show cars, but is an important part of yacht design too.

Our mockup taught us a lot about usability, ergonomics and structural design of the cabin.

As you can see, its a quick and dirty construction from scrap wood and paper boxes. All of that was recycled by us and therefor for free!

. . . and finished with paper sheets on! We made only one bow due a lack of material . . .
For comparison: this is how the windward hull looks like from above in a simple CAD model . . .
. . . and this is real life!
Having lunch in the surprisingly spacey insight of proasis! Four adults could sit there comfortably and sheltered for meals, two sleep in the cozy bunks in each bow over night.
The design office got transferred into the mockup for a couple of days: after spending a lot of time inside there we are confident to build a suitable accommodation!
