A trimaran with a very important beam master
"Domus is a single-story house built around a courtyard known as an atrium, with no roof, and access to several rooms. Domus were found to have many living areas, including a kitchen, bathroom, dining room and bedrooms."
It is therefore to recall this beautiful house of Roman antiquity that designers Pieter van Geest and Rob Doyl have conceived the Domus concept. It is a 40-meter superyacht trimaran with a very large 35-meter beam that allows for a single level layout, comparable in surface area to an 80-meter monohull, according to the design duo.
"Wide trimarans have proven to be faster than catamarans of the same size. This is the case in offshore/inshore races around the world and notably in 2010 with the victory of BMW Oracle (a 27m trimaran) over Alinghi (a 27m catamaran)" begin the two designers.
"We believe that from 40m upwards, if you want to enjoy the benefits of a multihull, the only practical solution is a trimaran. The research undertaken on multihull superyacht sizes between 80/90m and 40/50m clearly proves this." continue the designers.
A central hull dedicated to on-board systems
Without going into too much detail, Domus can sail on two hulls, with a rather reduced heel angle of 2°. This configuration allows the trimarans to reduce drag and therefore be faster in comparison to a catamaran sailing on its two hulls. All the systems and engineering are in the central hull and not in the two floats. Finally, the rigging forces are also taken on the central hull, which simplifies the arm structures and makes the overall structure simpler.
Zero emission navigation
Domus combines solar panels, hydrogenerators and a hydrogen fuel cell for an announced unlimited autonomy with zero emissions. This optimized solar energy management system allows the boat to run on batteries at night for silent and clean moorings.
A living space on one level
The very large interior space is mainly distributed on one level, without steps. All spaces have a view to the outside. The central hull houses the onboard systems. As mentioned, it carries all the rig loads and serves as the main service area (galley, laundry, crew quarters) and the side floats are dedicated to storage. The full width main deck houses the guests and the owner.
On paper, it is a nice promise, but this concept will have to be fleshed out to study its feasibility. If it is zero emission when sailing, the impact of building such a machine remains important.
