Entry & progression
Builds on: L1.1. Feeds: the sea-service calculation in L1.4 and the chart plot module (Q172), which is only examined on the near-coastal route.
The three routes
| Route | Where it is valid | The service that earns it |
|---|---|---|
| Near coastal | Domestic near-coastal waters, the Great Lakes, and all inland waters | 12 months' vessel operation, of which 3 months on ocean or near-coastal waters |
| Great Lakes and inland | The Great Lakes and inland waters | 12 months on Great Lakes or inland waters, of which 3 months operating on the Great Lakes |
| Inland | All inland waters except the Great Lakes | 12 months' vessel operation |
The hierarchy runs downward. A near-coastal OUPV carries the Great Lakes and inland waters with it (46 CFR 11.467(b)). An inland OUPV does not reach the other way. Apply for the highest route your service actually supports — you get the lower ones free.
The 100-mile cap that catches everyone
For every credential except the OUPV, 46 CFR 10.107 defines near-coastal as ocean waters not more than 200 miles offshore. For the OUPV, the same section cuts it to 100 miles. 46 CFR 11.467(b) says it again, and the NMC checklist prints it in bold: "Always limited to not more than 100 miles offshore."
So an OUPV near-coastal and a Master 100 near-coastal are not valid on the same water. The Master reaches 200 miles out; the six-pack stops at 100. If you read "near coastal" as one fixed distance, you will one day be a hundred miles beyond your licence.
NOTE — There is no ocean OUPV Near-coastal is the ceiling. The Coast Guard does not issue an OUPV for oceans, and no amount of blue-water time will produce one. If you want to work offshore, the OUPV is not the credential you are looking for.
Inland service as a substitute
Inland time is not worthless on a near-coastal application, but it is capped. Under 46 CFR 10.232(b), service on inland waters other than the Great Lakes may substitute for up to 50 percent of the total required service toward a near-coastal endorsement. Great Lakes service is credited day-for-day with no cap.
That 50 percent is a ceiling, not an entitlement. The 3 months of genuine ocean or near-coastal operation required by 11.467(c) sits underneath it and cannot be substituted away.
Two more routes worth knowing about
46 CFR 11.467 also provides two narrower endorsements that most candidates never hear of, and that occasionally solve a real problem:
- Limited OUPV (11.467(f)) — for people employed by formal camps, yacht clubs, educational institutions and marinas. Only 3 months of service on the type of vessel concerned, plus an approved safe boating course and a limited examination. It is restricted to that employment and that activity.
- Restricted OUPV (11.467(g)) — issued by the local Officer in Charge, Marine Inspection for a specific body of water. Again 3 months of service on the type of vessel and on each body of water concerned, and a limited exam.
Both require OCMI approval, and the OCMI may reduce only the sea service, the age and the examination. Everything else — medical certificate, drug test, fees — still applies in full. They are narrow tools, not shortcuts.
Choosing your route
Apply for the route your logged service genuinely supports. An evaluator who finds you 40 days short of near-coastal will not quietly issue you the inland ticket — the application comes back, and you start the clock again. Count your ocean and near-coastal days before you file, not after.
