100 ton captain license requirements in Maryland
Maryland 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 Annapolis, Chesapeake Bay, Ocean City, where the business goal is often a larger inspected passenger vessel rather than a six-passenger OUPV boat.

Local operating context
Chesapeake Bay charter is a strong segment — OUPV Inland covers most bay-only operators. Ocean City offshore canyon runs require OUPV Near-Coastal or higher. 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.
Questions candidates ask before applying
What are the 100 ton captain license requirements in Maryland?
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.
Can I get Master 100 if most of my time is on small boats?
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.
Where does a Maryland Master 100 candidate take the exam?
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.
