If you're considering becoming a licensed captain, you'll quickly encounter two terms:

OUPV and Master.

They're not interchangeable, and choosing the appropriate credential depends heavily on what you want to do on the water.

What Is an OUPV License?

OUPV stands for Operator of Uninspected Passenger Vessels.

It's commonly called the 6-Pack license because it can allow an operator to carry up to six paying passengers on qualifying uninspected passenger vessels.

This can be attractive for people interested in activities such as fishing charters and other small passenger operations.

What Is a Master License?

A Master credential can provide broader operating authority depending on its route and tonnage limitations.

You may encounter credentials such as:

  • 25 Ton Master
  • 50 Ton Master
  • 100 Ton Master

The appropriate tonnage isn't simply something you choose because you want the largest credential. Your documented experience and the vessels on which you accumulated that experience can influence what you qualify for.

Which One Should You Pursue?

Think about what you actually want to do.

If your goal involves operating a smaller uninspected vessel with no more than six paying passengers, OUPV may meet your needs.

If you expect to operate inspected passenger vessels or want broader professional opportunities, pursuing a Master credential may make more sense.

Your Sea-Time History Matters

This is where good recordkeeping becomes particularly important.

Don't just record that you "went boating."

Keep information about:

  • Which vessel you operated
  • When you operated it
  • How long you were underway
  • Vessel characteristics
  • Waters operated
  • Your role aboard

That history can become important when determining which credential you may qualify for.
