Parametric design
The boat was designed using Solidworks. The use of this parametric software enables the Yacht Concept team to adapt the model more easily to customer requirements. For example, a coachroof can be lengthened without re-modeling the entire part.
Upside-down construction using flat panels
The catamaran has been designed with developable shapes, so that the length of the boat can be easily modified to suit the customer. It can thus be built using flat composite panels, produced on marble. The 27x4.7 m panel produced by Techni-Yacht Pinta allows the planking of the 85-footer currently under construction to be laminated in a single piece.
The bulkheads, installed upside down, are joined to the planks to create the floats. The bulkheads are then turned upside down and connected to the beams.
Limit elements
Samples are calculated to limit the number of parts and assemblies required. The bulwark, for example, is made of a thick sandwich to eliminate the need for jambs. Aesthetics and construction come together. 
First 85-footer under express construction
The first Day-One, an 85-footer is currently being assembled at Techni-Yacht Pinta. Signed on November 15, 2015, construction began in early January 2016 and she will be delivered on June 15, 2016. It's the absence of molds that allows a custom build in just 6.5 months.
Costs equivalent to the series.
Between ?500,000 for the 50-footer and ?1,500,000 for the 85-footer, that's the range announced by Day One. These costs are comparable to production units with the same options.
Day-One's new offering is a tailor-made, personalized platform in a static market. According to Laurent Da Rold, feedback has been positive. To be continued...
