Entry Requirements

1. 50 days on board a yacht at sea as an active crew member. A day is defined as a period of 24 consecutive hours. Parts of a day may be included in this total, but a day is not invalidated by a candidate leaving the yacht for a few hours during a cruise. The term “at sea” is defined as being on a vessel outside of any harbour – natural or artificial – in which a cruising yacht could secure or anchor for a prolonged period of time.

2. Have logged 3,000 miles in a yacht while cruising at sea (power or sail). This mileage must be logged on genuine cruises or passages but not short day trips. At least 2,000 miles must have been completed on coastal voyages and not ocean crossings. It is important that the candidate has considerable time of actual vessel handling.

3. Thirty hours on watch at night underway as an active member of a yacht’s crew. For at least six hours of this night time experience, the candidate must have been acting as the vessel’s captain/watchleader. “Night,” in this context, is defined as the time between sunset and sunrise.

4. A current medical examination and a colour blindness eyesight examination, which allows the participant to safely perform the relevant duties on a yacht, including being able to see and distinguish lights and signals of other vessels and navigational marks in typical weather conditions without risk to him/herself, other crewmembers or the safe operation of the vessel.

5. A six-hour VHF Radio Operators course covering the general rules and procedures for the safe operation of a VHF marine radio. If you do not have a valid VHF certificate this course may be conducted on board the yacht or in the classroom prior to joining the practical course.

Minimum sea time must have been met prior to the final examination.
