Master 100 and 200-ton

Master 100 and 200-ton Class

To explain, the Master 100 and 200-ton class is in fact two classes. Consequently, they can be taken back-to-back as one 14-day class. Or one at a time as individual classes, depending on your needs or schedule. The following subjects are covered this class.

  • Navigation General
  • Chart Navigation
  • Rules of the Road (72 COLREGS)
  • Deck General
  • Safety

Firstly, the Master 100-ton class: 10-days, $1,300

The Master 100-ton class includes both the Inland and Near Coastal routes. Secondly, it includes the 25 or 50-ton limits, and the Mate 100-ton as well.

Any applicant who has successfully completed your Master 100 Tons (COLPAC-281) course within one year of application will satisfy the examination requirements of 46 CFR 11.201(j) (1) for original issuance, 46 CFR 10. 227(e)(1)(iii) for renewal, and 46 CFR 10.227(i) for reissuance of a Master of vessels of less than 100 GRT (Near Coastal, or Great Lakes & Inland, or Inland Waters); AND Operator of Uninspected Passenger Vessels (OUPV) (Near Coastal, or Great Lakes & Inland, or Inland Waters).

Secondly, the Full Master 200-ton class: 14-days, $2,000

The Full Master 200-ton class includes two classes taken in sequence. As above, this class includes both Inland and Near Coastal routes and both the Mate and Master license as well. To clarify, this combined class is best for mariners who qualify for both the Master 100-ton, and Mate 200-ton licenses.

Lastly, the Upgrade 100 to 200-ton class only: 4-days, $700

The Upgrade 100 to 200-ton only class is for mariners who already have a Master 25, 50, or 100-ton Inland or Near Coastal license. In short, this class is an easy way to a 200-ton license, but it will not change the route. To change the route the mariner can take the Upgrade Master Inland to Near Coastal Class.

Any applicant who has successfully completed your Upgrade Master 100 Tons to Master 200 Tons (Near Coastal) (COLPAC-526) course and presents your Certificate of Training within one year of the completion of training, will satisfy the examination requirements for upgrade of a merchant mariner endorsement as Master not more than 100 gross tons (or Self-Propelled vessels of less than 100 Gross Registered Tons) Upon Near Coastal, or Great Lakes & Inland, or Inland Waters to Master or Mate of Self-Propelled vessels of less than 200 Gross Registered Tons Upon Near Coastal, or Great Lakes & Inland, or Inland Waters.

Master 100 and 200-ton License Info

These licenses are issued as Inland, Near Coastal, and Oceans routes. To explain:

  • Firstly, Inland means all lakes, rivers, and bays shoreward of the boundary line. To clarify, this a line between the ends of the jetties.
  • Secondly, Near Coastal means all inland waters, and ocean waters within 200-miles of shore.
  • Thirdly, Oceans means all Inland, Near Coastal, and Ocean waters worldwide.

In addition, tonnage limits also apply to Master and Mate licenses. These limits are 25, 50, 100, and 200-ton based on the applicant’s experience. View the checklist the license for more info on its tonnage limits.


Master and Mate License Explained

The Master license is issued with an Inland, Near Coastal, or All Ocean route. Additionally, it includes tonnage limits of 25, 50, 100, and 200-tons. There are also higher tonnage limits, 500 and more, which are not discussed here. To explain, the Master is the captain in charge of the entire vessel. Therefore, the holder of a Master license may work as captain or mate on any vessel, except towing vessel, within the limits on the license. Including working as an OUPV 6-pack captain.

The Mate license is issued with the same routes and tonnage limits as the Master. But they cannot work as captain of the vessel, except for a 6-pack. The job of the mate is to stand a navigation watch under a licensed captain. However, the good news is that Mate can upgrade to Master of the same tonnage and route without taking an exam. Therefore, if you don’t have the time for master, get the Mate of the same tonnage and upgrade later.
