The IYT Master Of Yachts 200 Tons Unlimited Certificate (Previously Known As Yachtmaster Ocean) is a qualification that indicates that the holder has sufficient knowledge of celestial navigation to navigate globally using a sextant and to plan, undertake and manage an ocean passage with a comprehensive understanding of the factors involved with regard to routing and weather/climate.

Master of Yachts 200 Tons Unlimited Qualifying Requirements

Requires: Master Of Yachts 200 gt Limited or MCA OOW (Yachts)

Prior to taking the course candidates must have undertaken either two voyages of 250 miles or one voyage of 500 miles of which the majority must have been out of sight of land i.e. 20 miles or more from a shoreline. It is expected that a passage plan is made for the qualifying voyage for subsequent review during the course. Although it is strongly preferred that the passage/s be carried out prior to the course being taken, this may be done after the course if there are extenuating circumstances.

In addition, candidates must hold a valid IYT Master 200t Limited Certificate of Competency or an MCA OOW (Yachts) certificate but no prior knowledge of celestial navigation is required.

Students that hold an OOW (Officer Of The Watch) with Command Endorsement may proceed directly to the IYT Master of Yachts Unlimited course.

The Master of Yachts 200 Tons Unlimited Program / Curriculum

A six-day comprehensive course on celestial navigation aimed at equipping the candidate with sufficient knowledge of celestial navigation to navigate the globe using a sextant and air navigation tables as well as to plan, undertake and manage an ocean passage.

Apart from the qualifying experience the requirements for the issue if the Certificate of Competency are threefold:

  • Achieving a pass mark in a three-hour written examination on the last (6th) day of the course.
  • The demonstration of practical sextant competencies including the taking of sun sights during the course.
  • The submission of a formal plan for an ocean passage. In this respect candidates have Two Options Below:


1) During the Course. Plan an imaginary ocean passage under examination conditions using materials supplied by the school. The passage planning exam is evaluated before the end of the course so that remedial action can be taken. This option is subject to severe time constraints but does allow for the fact that many vessels are not equipped for celestial navigation.

– OR –

2) After the Course. Plan, execute and manage an actual ocean passage (600-plus miles out of sight of land) during which positions have been derived by celestial means. A formal submission must be sent to the school for evaluation within 12 months of course completion. This option is only possible for candidates who have access to the equipment and publications needed for celestial navigation. Candidates can expect an extremely steep learning curve on this course but the satisfaction of having acquired a brand new skill from scratch is reward in itself.
