About Invictus Yacht

Premium production

Italian builder of design-led open and hardtop boats from Calabria — thirteen models in the GT, TT and ST series, from the 8.9-metre GT280 to the 16.9-metre TT550 and ST550, all designed by Christian Grande and built by Aschenez at Borgia.

Invictus Yacht is built by Aschenez Shipyards, which the yard says bring together more than twenty years of experience in building pleasure boats. Production is vertically integrated, with up to 90% of the work carried out in-house by more than a hundred people, on a site of 20,000 sqm of which 9,500 sqm are covered: offices, moulding, painting, a test basin where every system of each boat is checked, assembly, finishing, a furniture workshop, carpentry, electrical systems, an RTM department, a textile division and the Atelier Invictus. Hulls are infused in fibreglass and carbon fibre, and the yard lists its newer steps — structural tanks, pre-preg carbon, recyclable honeycomb panels for the sub-deck walls and resin-infused high-density polyethylene in place of internal wooden structures. It names the GT280 Carbon Look, whose black finish is a clear treatment over bare carbon rather than paint, as a milestone. Hull colour has always been part of the brand: seventeen options, metallic or matt, in classic and extended versions.
