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

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.

Great experience

I had a great experience obtaining my TOAR, starting with great communication with Sam via emails and cell. Ben was my DE and was very professional and a wealth of Knowledge. I would recommend Diamond Marine Services to everyone. I have been a mariner for 23 years and was still able to learn a few new things. Great people. Thank you

Had an absolutely wonderful experience doing the TOAR Class with Birk in Boston. He`s a true professional and awesome teacher -- he knows a ton about shiphandling and towing. I got a lot out of a class that was only a day long -- way more than I think I would have gotten out of a weeklong simulator course. It`s so much better to get out there with the environmentals on Boston Harbor and actually get a feel for a real boat when you`re maneuvering alongside a tow. Also wanted to thank Sam for working with me and my company last minute to make this class happen. He went out of his way to answer all my questions, and even got back to me via email on a couple nitpicky regulatory things he didn`t have answers for when we spoke initially. Can`t say enough good things about Diamond Marine. If you need to get your TOAR Card signed off, this is the place!

I received more than I hoped for. Sam went far beyond my expectations. Diamond Marine communicated with USCG evaluators on my behalf and resolved issues quickly. I enjoyed the entire learning process aboard the vessels.

Sam and his team were very courteous, knowledgeable and efficient. I took the inland TOAR in Boston Harbor and learned a great deal in vessel and tow maneuvers with Ben and Caitlin. Everyone was very skilled and friendly. I also had their credentialing service advise me in getting my application into the USCG whilst also applying for a license I didn't know I was eligible for. They can save you a lot of time and money as opposed to figuring this out by yourself.
