Greywing is a platform for ship operators to automate their business, through actionable intelligence, better data and communication. Greywing today serves three product lines to customers: *Flotilla* is a monitoring tool for vessels, enabling vessel managers to identify fleet-level patterns and optimizations and to identify risk and liability vectors in advance. *CRY4* is an operational tool for individual vessels that allows crew managers, security officers and masters to gather intelligence about a vessels current or proposed route, making decisions about the safest and the cheapest ports of call that a vessel can be directed to. *Landfall* is a crew management and analysis system to provide risk reporting and detailed editing capabilities about the crew on-board a vessel. *Semaphore* is a port-agent communications tool meant to simplify the process of interfacing with large numbers of port agents while planning a port call.
