100 ton captain license requirements in Florida

Florida 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 Key West, Islamorada, Marathon, where the business goal is often a larger inspected passenger vessel rather than a six-passenger OUPV boat.

Sea time: Commonly 720 days
Exam focus: Rules, deck, safety, navigation, plotting
Local signal: Key West + Islamorada

Local operating context

Florida has by far the highest charter density in the country. REC Miami runs the federal exam; OUPV Near-Coastal is the standard entry credential for offshore reef and bluewater operators, with Master 100 common in the Keys and on the Gulf coast. 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 Florida?

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 Florida 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.
