Bridge Refresher Course

Carried out by our in-house Master Mariners, the Bridge Refresher Course is designed for a variety of situations. It can be for active yachts who want to brush up on skills, boats that have been in the yard for extended periods, or new-builds during the last stages of the build to refresh skills that may not have been actively used for long periods.

The course is open and available to all crew members; however, it is tailored more to Masters, Officers and Navigation or bridge team members.

With this course, your knowledge will be enhanced or refreshed on all things ECDIS and the use of bridge equipment.

ECDIS Risk Assessment

ECDIS Risk Assessments need to be simple, practical and meaningful; however, fast-changing technology and regulatory environments mean the quality of assessments can vary significantly. The requirement to submit a formal Risk Assessment to a vessel’s Flag State when navigating primarily on an ECDIS no longer exists; nevertheless, MGN 285 strongly recommends a Risk Assessment is conducted.

dsnm and Master Mariner George Mills use their experience and deep regulatory understanding to support Captains and crews with world-class Superyacht ECDIS Risk Assessments. We aim to proactively get under the skin of yacht-specific ECDIS challenges whilst identifying and delivering practical, future-proof solutions.

With this course, your knowledge will be enhanced or refreshed on all things ECDIS and the use of bridge equipment.
