A premium, and sustainable solution: anchor into the elite marinas of tomorrow. DOCKER has a built-in system of winders that serve users in managing and controlling energy consumption – water, electricity, and waste water. Allow boaters complete control over their own connection, even when they’re not on the vessel. DOCKER enables the control of moorings via this mobile application which helps in planning the user’s sailing by enabling online booking of moorings in transit marinas. Supplying electricity and water has never been simpler with this complete and unique docking system. DOCKER is an all-in-one solution for both marina operators and users. Considering the systems it offers, the marina takes on a clean, modern, and safe look. It also comes with a SMART system, allowing marinas to optimise the costs. Users no longer need to store cables and hoses on their own vessels, which frees up storage space. Users can also access fully automated systems for supplying electricity and drinking water.
