The current thread on sextants/astro has made me wonder what really ought to be on the RYA Ocean YM Syllabus.
Surely the purpose of the Ocean YM should be to ensure people have the necessary skills to navigate safely across Oceans. From my memory of the theory I did years ago it seemed to concentrate on two aspects (a)Astro Navigation and (b) Tropical Revolving Storms.
Useful though those may be I would question whether they are really the most important issues for someone planning to cross an Ocean.
IF the purpose of the course is to be relevant to a leisure sailor then surely it should be updated to reflect modern priorities. E.g. I would suggest adding
(a) More information on long range communication (SSB and Satelite)
(b) More about weather forecasting in the oceans
(c) Maybe more First Aid
(d) Handling emergencies - e.g. how to survive in an Avon liferaft for 189 days
(e) Maybe visa/border issues?
(f) GPS?
Now I very much enjoy Astro navigation but in these days I would question whether a sextant, Nautical Almanac and Astro Tables (all cost money and take space) should be regarded as essentials for the leisure sailor. Rather than concentrating on star fixes and the like, why not change the focus to "emergency Astro" - in otherwords basic techniques to aid location in the event of GPS failure but not requiring masses of tables and equipment.
For example given an accurate watch you can get a reasonable position from a basic observation of the meridian transit of the sun using a couple of very simple figures per day.
