“A huge thank you for all your valuable assistance throughout the re-imaging“
Fleet Captain of M/Y Dragonfly and the Fly Fleet
On behalf of the Dragonfly Bridge Team, we wanted to say a huge thank you for all your valuable assistance throughout the re-imaging of the Transas Unit. Given the time of year and proximity to a guest trip, we were in a very tricky situation, which your help and diligence avoided. We are extremely lucky to have your support and look forward to any future work with you.

“They perfectly simplify what can be a complicated world of competing systems“
Jack Howarth, Chief Officer, ex-Talisman Maiton
The team at dsnm, and in particular Sally, have always been a great support of mine. Always polite, friendly and willing to help, they perfectly simplify what can be a complicated world of competing systems, into one complete and holistic package. The compass website continuously receives updates and new features, adding greater value to what was already a useful platform. As the marine industry moves digital, I cannot stress enough the value of having everything accessible in one place and with a team of professionals to support you when the tech goes wrong.

“Continuously evolving and improving the workings of their systems for ease“
Jarred Adlard, Chief Officer - M/Y Lightning
It has been an absolute pleasure working with dsnm. Six years of being a committed client should say it all! The company has expanded their services to meet the modern era and are continuously evolving and improving the workings of their systems for the ease and beneficial use of the customer. That, alongside having worked with the same fleet manager for 6 years who knows the runnings and expectations of the vessel makes for a great professional relationship. Again, another testament to the running of the company, holding the same staff.

“Intuitively provide suggestions for necessary charts, publications and resources“
Tom Jakubik, Captain, M/Y Kogo
Having worked with Lizzie and the team at dnsm for well over a year now, I can say their services are second to none. They take a proactive approach when dealing with the yacht’s navigational management and almost intuitively provide suggestions for the necessary charts, publications and other related resources which may be required due to regulatory or practical reasons to affect a safe passage or cruising in a specific area. I would highly recommend their services to any yacht master in the industry.

“dsnm makes keeping on top of our onboard chart portfolios so easy“
Archie Robinson, Second Officer, M/Y Flag
We have been using dsnm onboard now for almost 5 years! dsnm makes keeping on top of our onboard chart portfolios so easy so that onboard I can focus my attention on other operational tasks. The service is proactive in letting us know when issues are up for replacement and never fail to deliver them to our desired port on time. They are so flexible, which for our changeable program and cruising plans is essential.

“dsnm are always looking to make compass a better experience“
Josh, Chief Officer, Yacht Name Confidential
compass is an amazing program. It makes life on the bridge a quicker and more efficient process. Passage planning, weekly corrections, active T&P’s and folios are all there at your fingertips in compass. The dashboard is a fantastic visual, you can clearly see what is outstanding in corrections, weekly check list items or new editions and expiring items that you need, at a quick glance. dsnm are always looking to make compass a better experience by adding in new features and listening to what we have to say to help improve the site. Would highly recommend jumping ship to dsnm.

“The main idea behind Compass is something that we onboard really like...“
Tim, Chief Officer, M/Y Lemon Tree
We have been using Compass since the launch of our new vessel – we utilise all aspects of Compass, from the Passage Planning tools with new and improved weather overlays, to the full Nav Management tool for monitoring new editions and licences renewals – we have also started to use the new MARPOL function that has been recently introduced, and it is working really well. The main idea behind Compass is something that we onboard really like as it combines all our navigation requirements into one central location to help make our lives as easy as possible during busy owner trips and charters. We look forward to continuing to see the new and exciting developments to come from dsnm and the Compass platform.
Tim, Chief Officer, M/Y Lemon Tree
