The Technology

Sammy combines different technologies and services to an integrated powefull & realtime platform that hosts multiple yachting marinas, connecting them with the yachting community.


A multi-purpose group of sensors is installed in the marina for monitoring the status of the berth spaces, measuring the sea level & water quality and observing the weather condition.


A cloud based infrastructure is exploited for serving a large number of marinas, maximizing the scalability and availability of the system, providing real time services and enhanced management features.


Pricing policies and intimate e-booking services are provided through the mobile app or the web site, supporting booking modification and keeping the history of the booking activities.
