When should you worry if someone is late back from kayaking?
Act immediately on a distress message or evidence of danger. If a kayaker misses the agreed return or check-in, use the float plan, try to establish contact promptly and contact the appropriate rescue authority if you remain concerned. There is no universal safe waiting period. Do not wait for another app alert or treat movement on a live map as proof that the paddler is safe.
Use the plan and report what you know
01Respond to known danger immediately
A request for help, a reported capsize or other evidence of an emergency calls for emergency assistance now. In the U.S., call 911 when you need emergency help; in the UK or Ireland, RNLI guidance for coastal emergencies is to call 999 or 112 and ask for the coastguard. Elsewhere use the local emergency number. Do not postpone that call to complete the checks below.
02Find the return agreement and last direct message
If the concern is an unexplained late return, open the float plan. Confirm the expected landing point and what “back” meant. Try the paddler and any named trip contacts promptly to establish whether someone has heard from them. Follow the plan’s action instructions; repeated unanswered calls should not become an improvised waiting period when you remain concerned.
03Record facts without interpreting the map as a rescue assessment
Note the time and content of the last actual message. If you have a live link, record the location shown and its update time separately. Report an old position as old, and avoid converting a dot’s speed or direction into a claim about the paddler’s condition. The GPS accuracy explanation describes why a displayed point also has uncertainty about where it places someone.
04Contact the authority responsible for the water
Use the rescue contact listed in the float plan or the appropriate local emergency service. Say that a kayaker has not returned or checked in, explain why you are concerned and distinguish known facts from assumptions. The U.S. Coast Guard Auxiliary’s Boating Emergency Guide directs concerned plan holders to the rescue authority and its dispatcher. You do not need a complete information pack before making the call.
05Share useful details as they become available
Have the launch and intended landing, route, number of people, kayak description and last communication ready if known. A possible opening is: “I am the contact for a kayaker who has missed the agreed return. I cannot confirm they are safe. They launched at [place], planned to land at [place], and last contacted me at [time].” Give the dispatcher your callback number and follow their questions; say “unknown” when that is the accurate answer.
06Stay available and update responders
Keep your phone available for follow-up. Pass on new messages, including confirmed safe return, to the authority you contacted and follow its instructions. Do not launch your own search or enter the water to investigate. If other people hold copies of the plan, keep them informed of confirmed facts so a fresh rumor or an old map screenshot is not mistaken for a new development.
Related questions
Should I wait an hour before calling?
There is no fixed delay that is safe for every paddling trip. Use the agreed plan and what is happening; seek assistance promptly if concern remains. Known distress needs immediate action. An app’s timer or grace period is a software setting, not a rule about when you are allowed to call for help.
The location is still moving. Does that mean everything is fine?
No. It shows reported movement of a device, not the condition of the person. Share the location and timestamp accurately if responders ask. Do not label it normal paddling or drifting, and do not cancel a concern solely because the dot moved.
What if there is no float plan?
Contact the appropriate authority with what you know. Look for useful trip messages or ask named companions, but do not delay an urgent call while gathering every detail. The Coast Guard Auxiliary’s emergency guide includes a path for people who were not given a plan.
Does acknowledging a Holler alert send help?
No. It shows that someone is checking the alert. Holler does not contact emergency services or dispatch a rescue. A Guardian still needs to call the appropriate authority when help is needed and communicate any confirmed resolution to other contacts.
