FREE to download and FREE to create a user profile, the Offshore SMS has been developed to give commercial vessel owners, skippers and crew the tools they need to be safe on the water, anywhere in the world. Every vessel should have a safety management system (SMS) or safety management plan, and everyone on the boat, from the owner to the crew, must know where it is, what is in it, and how to use it. The OffshoreSMS app makes this easy! Owners and masters can build and update the SMS in real time from anywhere on earth.
