Delaware candidates targeting Master 100 GT should separate two questions before applying: whether they have enough Master-level sea time, and whether enough of that service was on vessels large enough to justify the 100 GT tonnage limit. That distinction matters for operators working around Lewes, Indian River Inlet, Delaware Bay, where the business goal is often a larger inspected passenger vessel rather than a six-passenger OUPV boat.
A Delaware Master 100 GT application has to clear the Master less-than-100 route baseline and then show enough qualifying service on larger vessels for the 100 GRT limit. The NMC can still issue 50 or 25 GRT if the sea time is valid but the vessel tonnage is smaller.
Great Lakes/Inland uses a 360-day baseline, while Near-Coastal uses 720 deck-department days on ocean, near-coastal, or Great Lakes waters, with up to 360 inland-water days allowed as substitute service.
The current NMC checklists show 100 GRT supported by service on 34+ or 51+ GRT vessels, with the day threshold depending on route. Valid Master service on smaller vessels can still produce a 50 or 25 GRT credential.
Most Delaware charter captains run OUPV Near-Coastal for canyon trips out of Indian River Inlet. The nearest REC is Baltimore. For exam prep, the federal question set does not change by state, but your likely route matters: inland candidates lean harder on Inland Rules and aids to navigation, while near-coastal candidates need COLREGs, navigation, weather, and chart-work discipline.

The credential is federal, so the requirements do not change by state. A typical Master 100 GT applicant documents Master-level sea service, passes the required USCG exam modules, clears medical/drug/TWIC screening, and shows enough qualifying vessel tonnage for the 100 GT limitation.
Not always. The Coast Guard issues 25, 50, 100, or 200 GRT limits from the vessel tonnage in your qualifying service. Small-boat time can satisfy days, but it may cap the credential below 100 GT.
After the NMC approves the application, candidates test at a Regional Examination Center or through an approved course provider. Use the nearest REC listed above for planning travel and appointment timing.
