Explanation:

We take "vessel" in this context to mean any powered water, land, or air craft. The hazards in these different areas tend to differ. In general, a speed is considered safer if it is slower, but there may be instances where a minimum speed is required (as for landing an airplane or orbit in space). In the case of watercraft operating in extreme weather and/or wave conditions, both speed and direction are important.

Safety of operation involves a number of factors, all of which must be observed:

posted speed limits, or other legal limits
visibility limits and safe turning/stopping distance
limits published by the vehicle manufacturer, both for normal operation and operation in unusual environments
the state of operability of safety features (brakes, restraining harnesses, escape routes)
environmental conditions, including collision hazards
probability of sudden changes in these conditions.

What constitutes a hazard to the operator, passengers, environment, or vessel may change in the course of operating the vessel, so the safe speed may change, possibly rather suddenly. Safe operation would take that into account, along with the possibility that different observers may judge the hazards differently.

__

One could say you are operating at a safe speed if you are complying with published limits, and you are not presenting any hazard to anyone or anything around the vessel, or to anyone or anything inside the vessel, or to the vessel itself.
