Yacht and Marine Vessels Design Project Monarca Day Boat by Onur Kiren Project Monarca is a 13 meter day boat with a sculptural hull and fluid, organic lines inspired by the movement of water. Continuous surfaces create a distinctive identity and support hydrodynamic efficiency. Compared with typical boats of this size, Project Monarca adds optional living and relaxation areas. Opening side terraces at the aft enlarge the deck space and strengthen the connection with the sea. The hull and superstructure are made of glass reinforced plastic with a foam core, produced by vacuum infusion in female molds.
