Yacht and Marine Vessels Design Project Monarca Day Boat by Onur Kiren The 13 meter day boat presents a sculptural approach to marine design, defined by fluid, organic lines inspired by water movement. Continuous surfaces create a distinctive identity while improving hydrodynamic performance. Compared to conventional boats in this segment, it integrates optional living and relaxation areas to enhance comfort and versatility. Opening side terraces at the aft expand deck space and strengthen the connection with the sea. Material selection and balanced colors support a refined, contemporary luxury expression.
