Nobody likes to do the packets of paperwork needed for your renewal.
Check marks, do I need, converting documents and paying the government.
Diamond Marine Services is able to walk you through the process with professional knowledge.
Don’t worry about faxing or scanning. That’s old school.
They are able to get the Coast Guard your documents in seconds.
Emails and questions are answered quickly. Filed paperwork on Feb 11th, credentials approved Mar 24th.
Thanks for your help.

Dealing with the Coast Guard has become difficult and time consuming. I am not always able to have Internet access while on the job. Since I began working with Diamond Marine Services, I don’t have to worry about missing an email from the Coast Guard or having my credentials delayed because I overlooked something in the paperwork. They have simplified the system for me and I recommend them to anyone in our career field.

I highly recommend this class. My instructors were Sam and Birk. What both instructors are good at is 2 very important things in particular:
They’re experienced Captains AND they’re good teachers and that’s what you want in an instructor, someone who not only knows the material but has the patience to explain why a maneuver or something else will or will not work. Another great thing is these guys are going to let you drive and get your hands dirty. Great job guys.

I came to Diamond Marine to get my TOAR completed, and walked away with a Master of Towing. There were many challenges, but what I appreciated was Sam’s patient solution oriented mentality. He solved every obstacle with speed and and accuracy. He even gave additional advise in regards to submitting my application. I would recommend this course for anyone who wants to get their Mate or Master of Towing.

Best TOAR Assessment Class ever! The most fun I have had taking a maritime class.

Rated 5 out of 5
January 8, 2021

In all my years of taking hands on and practical skills classes for the maritime industry, this one is the best I have ever done. The Designated Examiner for the class was knowledgeable and well seasoned in the towing industry and always willing to impart his knowledge and experience onto the class. The tug was an “oldie but goodie” making it a great platform to learn and practice the basics of tug and barge maneuvering before getting overwhelmed by the high speed and low drag controls of modern tugs. In the class each student takes a turn driving the tug doing each maneuver for the TOAR until they were successful with it. They also have a barge that is used for all maneuver, with the instructor going over the tricks of the trade on how to best complete them safely. Nothing in the class is simulated, it is all real world and hands on. I had so much fun in the class, I had wished it was more then just one day.

My overall experience with Diamond Marine Services and their affiliated partners was perfect ! Sam went out of his way on several occasions to not only answer complex licensing questions but ensure that the licensing process was stress free. The TOAR course was fantastic, filled with lots of hands-on practical assessments. The entire crew at Diamond Marine Services were extremely knowledgeable, polite, and professional. I would strongly recommend Diamond Marine services for all of you licensing needs.

This was a great class with plenty of opportunities to ask questions and to get amazing hands on experience. Sam and Birk were great to work with and made the whole process seamless. Their commitment to their customers doesn’t just end with the TOAR Class, they are more then willing to answer any questions that someone might have about licensing and the confusing process that come with working with the USCG. I will absolutely be recommending this class/their services to anyone that needs it.

So glad about hiring Diamond Marine to help me obtain my TOAR certification. Sam is super knowledgeable about the Maritime business and very helpful with any questions you throw at him. Captain Birk and the crew were just as professional, informative, and took the time to thoroughly train us. Five stars from me.

I took the TOAR class with Diamond and I recommend it to all my friends. It was a great class, and the customer service Diamond delivers walking you through the licensing process is above and beyond. 5/5 would use Diamond for classes and credential counseling and I already recommend it to my friends.

The TOAR class aboard the tug in Boston Harbor was extremely hands on and helpful. This is a great way to get time on a tug in a low pressure and professional atmosphere. I would recommend this class to any mariner who’s interested in getting their foot in the door in this industry.

USCG License Renewal

I am on my 8th renewal for my USCG License and normally I would do all the paperwork myself but with all the changes of staff and paperwork I decided to reach out to Diamond Marine Services and now I am glad that I did because the people doing the paperwork at NMC are not really up to speed anymore like they use to be so I had a few set backs because they kept asking for more and more documents but Sam was able to Liaison for me and this sped up the process. I would highly recommend using this service for anything to do with any License. Sam replied back to me on every query that I had and saved me a lot of time and headache since I was overseas trying to do this. Thanks for your professionalism and it is nice to find a company so qualified and also has the License/Skill and Knowledge to get things done.
