TOAR Detail

Towing Officer Assessment Record

TOAR Class Details

DIAMOND MARINE SERVICES has access to towing vessels and designated examiners that can help you with your advancement to Mate (Pilot) of Towing or Master of Towing. Since 2009, we have helped many mariners by providing a platform to complete both the maneuvering requirements as well as discussion based assessments in the Towing Officer Assessment Record. Our program utilizes a working tug and barge with a full crew in the presence of a USCG approved designated examiner.

30 Days of Training and Observation *NEW

As described in the towing vessel license pipeline towards the bottom of this page, any application for a mate or master of towing  license should also be accompanied with 30 days of training and observation on towing vessels. If you find yourself in a position where you need observation time, please let us know via the inquiry form or via email at office@diamondmarineservices.com.

Do I qualify to participate?

Our program is reserved for experienced mariners. Mariners holding an OICNW endorsed license (STCW II/1 or II/3) can complete all the assessments in the TOAR. If you do not hold an OICNW endorsement, you may be able to join us but we may not be able to complete the TOAR in its entirety. In addition, the extra sea service needed to upgrade to a mate or master of towing from a lower level license is often a surprise to many. For these reasons, we request to open a line of communication so we can better assess your needs. Mariners holding licenses LESS THAN 500 GRT (master or mate) or those without an OICNW endorsement are accepted into the class on a case by case basis. For more information about this, please submit an inquiry via the contact form below.

We operate in partnership with towing services home ported in Boston, MA. Please  visit our LOGISTICS page for more information.

Towing licenses explained

Not all licensed mariners can operate towing vessels.  In order to serve as a Mate or Master on towing vessels including push boats, wire boats, tractor tugs or ATBs, you need to hold a Mate of Towing license or a Master of Towing license.  We used to call these towing endorsements but they are now viewed by the USCG as licenses that have their own evaluation requirements as well as their own renewal requirements.  ALL towing licenses require you to complete a practical demonstration of maneuvering a tug & barge as well as complete a series of discussions specific to towing vessels.  The assessment of these demonstrations are observed by a Designated Examiner and recorded in your Towing Officer Assessment Record .

Sample checklists for towing licenses may be found here:

Master of Towing checklist

Mate of Towing checklist

NOTE: Checklists change frequently. Please visit the NMC website for the latest checklists.



What is a TOAR?

As outlined in NVIC 3-16, the Towing Officer Assessment Record or TOAR is required to document the demonstration of proficiency in the presence of a Designated Examiner.

The TOAR is broken out into seven sections:

  1.  Vessel Familiarization
  2.  Navigation & Piloting
  3.  Watchstanding
  4.  Maneuvering
  5.  Rules of the Road
  6.  Safety & Emergency Response
  7.  Environmental Protection

A TOAR is required if you are applying for any of the following:

  • Mate of Towing while holding a license as 200 GRT Master or less
    • 1080 days as Master required (on NON towing vessels)
    • 30 days of training & observation on towing vessels required
    • NOTE: Mariners holding a license as a Master 200 GRT or less must serve 360 days as a mate of towing before applying for Master of Towing
  • Mate of Towing while holding a license as 500 GRT Mate (or higher)
    • 30 days of training & observation on towing vessels required
  • Mate of Towing as a raise-in-grade from Apprentice Mate
    • 360 days serving as apprentice mate required
  • Master of Towing while holding a license as 500 GRT Master (or higher)
    • 30 days of training & observation on towing vessels required
  • Adding a new route to your current towing license
  • Renew current towing licence without required sea service

Totally worth it!

The class started right on time with the captain ready to go. We got onto the tug and quickly jumped right into learning about how the boat operated without a barge made up to it. We then went through several tasks to make up a barge and later operated with and without the barge made up. The captain was kind and helpful through every step of the process and the deck hand was a pleasure to work with. This was my first time ever being in the position to operate a tug and barge and I was nothing but comfortable and confident with the instructions given to me. Overall this is an amazing class and would recommend it to anyone looking to complete their endorsement requirements.

If you need a TOAR, call Diamond. I was in a pinch and needed to get this done ASAP. I called them up on a Wednesday morning and was on a plane a few hours later, headed to Boston. My class was scheduled for the very next day, Thursday, in Boston Harbor. I have nothing but positive things to say about them. Extremely accommodating. The assessments were explained clearly and concisely and executed under expert tutelage and I had an email in my email box with the completed assessment form before I even got out of the Uber to the hotel. … which, by the way, was another amazing experience. They recommend the Mariner House and I second this recommendation.
All in all, extremely positive experience. Don’t hesitate to call Diamond if you need to get this done.
