Completed in 2009, Antithesis was built to DNV classification and MCA compliance and features an optimized design that maximizes safety and environmental elements. For this build, Horizon switched from polyester resin to vinylester for the structural elements, including the hull, topsides and superstructure, as vinylester has shown to better resist osmotic blistering. Antithesis was also tested extensively to exceed the damage and stability requirements of the IMO HSC2000. The Espinosa/Marshall styling and design of Antithesis is further improved by efficiency-minded details such as low-level LED lighting throughout, large props with small shafting angles, fuel filling stations with overflow alarms, IMO-approved water treatment and water-treated stern bearings.
