Hot Lab’s 110-metre Primadonna superyacht concept, based on an Oceanco platform, makes thrilling use of dark windows to create some dramatic horizontal lines. But there is nothing gloomy about the yacht, which also makes great play of the available light: those windows are mostly full height. The on-deck features heighten the sense of playfulness. The signature Oceanco pool aft becomes an organic part of the beach club below, with water cascading down to a whirlpool area enclosed in glass panels so that it can be used all year round. Below the swimming pool is a beach club that has terraces on both sides over the sea. There is a forward touch-and-go helipad that has direct access to the owner’s deck. As well as the owner’s suite, there are six VIPs and two further guest cabins for 18 guests in all, along with 40 crew/staff. Visitors to the Oceanco stand at the Monaco Yacht Show in September can see a scale model of Project Primadonna.
