About the event

Our 100 Ton Master course will qualify you for a 25,50, or 100 Ton Master Credential. 

This is a combination of 2 courses; OUPV and OUPV to Master Upgrade.  To obtain a Master endorsement you will need to register for the follwing 2 courses:

OUPV (Operator of Uninspected Passenger Vessels) course


OUPV to Master Upgrade course

This is the same course, material, and exams that others offer as a stand alone Master course.  At Explorers Guide we seperate the two courses to better fit the needs of our students, with the same end result, a Master Credential.  You may take the courses in any order, but it is suggested to take the OUPV course first.

  • If you do not currently hold a mariner credential you MUST enroll in both courses to obtain a Master.  If you are looking to obtain a 6-pack, you only need the OUPV course.

  • If you currently hold an OUPV credential and wish to upgrade to a Master, register for the Upgrade OUPV to Master course.

  • This page is for information only and does not gurantee a seat in our OUPV or Master Course.  Please follow the steps outlined above to register and confirm you seat.
