I'm an engineer working on an autonomous boat project. I want to make sure I'm not breaking any laws, but I've been unable to find any laws specifically regulating drone boats (unmanned/autonomous). Is this simply a relatively unregulated area, or am I missing a bunch of regulations that do exist?
I'm specifically interested in regulations that govern when and where autonomous boats can travel, and any limitations on their use. For example, aerial drones can only be operated within line of sight. It seems like there are no such restrictions on drone boats.
I'm operating out of the US, but I'm interested in any relevant laws in the US or internationally.
