Common questions

What license do most Missouri captains get first?
Most Missouri operators start with the OUPV / Six-Pack (most common first license). Missouri's river systems and large inland lakes support towing and charter operations under inland OUPV licenses.
Is there a Missouri-specific version of the USCG exam?
No — the USCG written exam is the same nationwide, administered by the National Maritime Center. The only variations are the license grade (OUPV, 100 GT, 200 GT) and the route endorsement (inland vs near coastal), which depends on where you intend to operate.
How many questions are on the USCG exam?
It varies by license grade. The OUPV exam has approximately 125 questions across multiple modules; the 100-ton Master exam is larger. Each module is graded separately — Rules of the Road requires 70% (or 90% in some modules), and you must pass each section independently.
