Working mariners: is 30–180 seconds enough warning to do anything useful before a bad wave encounter?
Our take
Title: **Seeking Insights from Experienced Mariners on Wave Encounter Preparedness** I am reaching out to those who have worked aboard commercial vessels to gather insights on the practical implications of receiving a 30–180 second warning before encountering severe waves. Specifically, I want to understand if this time frame would allow for meaningful actions, such as changing heading, slowing down, warning crew, or securing gear. Please share your experiences, including your role, vessel type, and what actions you consider realistic within this time window.
Question for people who’ve actually worked aboard commercial vessels:
If you had 30–180 seconds of warning before a sudden severe-wave encounter, would that be enough time to do anything useful onboard?
I’m not asking whether the tech is realistic, I’m only trying to understand the operational side.
Would that kind of warning be enough to:
- change heading
- slow down
- stop exposed deck work
- warn crew / secure gear
- prepare on the bridge
Or is that window too short to matter in real life?
If you’ve dealt with fast-changing conditions at sea, I’d really appreciate your take.
Helpful context if you’re open to sharing:
- your role
- vessel type
- what action is realistic in that time window
- what minimum warning time would actually be useful
Not selling anything, just trying to learn from people with real experience.
