Celestial Navigation, the Easy Way!
Have you ever wondered what would happen if you were making an ocean passage, way offshore and out of sight of land, and all of your electrics failed? No GPS. No chart plotter. Nothing!
Would you be able to calculate your location?
All you would need would be a sextant, a chronometer, nautical almanac and HO 249 (or the British equivalent), of course the celestial bodies, chart, pen and paper, and knowledge in celestial (astro) navigation.
CBYA member, Rosalind Miranda, has written a successful book on celestial navigation entitled “Miranav: A workbook of celestial navigation for yachtsmen”.
Here is the Cruising World review of her book….
Consider this unique workbook a piece of safety equipment! It is totally waterproof and rustproof (plastic covers, pages and spiral binding) and will provide a reliable back-up to all electronics, including calculators. Unlike a book, Miranav can be submerged, dried off and immediately used….. a potential lifesaver! All theory has been removed, and the text is designed to take the navigator from Point A to point B with tested clarity. Instructions are given for obtaining Line of Position (LOP) using the sun, moon, planets or stars; for plotting a LOP, for getting a running fix, for finding both longitude and latitude at noon, for using Polaris to calculate latitude, and for using a RDF and the Star Finder and Identifier. The Miranav method uses HO 249 and Nautical Almanac, and use of Time Chart eliminates problems in determining G.M.T., no need for mathematical calculations. Clearly-written numbered instructions correspond to numbers on four laminated work-forms that are re-usable (grease pencil or felt tip pen wipes clean with a damp cloth). Miranav has been reviewed and rated excellent by Cruising World staff.
Rosalind has agreed to run several two-session celestial navigation courses for the CBYA this year. The course will use her Miranav method and will be free-of-charge for paid-up CBYA members. The proposed dates are:
Group 1 – 11 & 12 March 2020
Group 2 – 18 & 19 March 2020
Group 3 (if adequate interest) – 16 & 17 September 2020
Each sessionwill cover:
1) introduction & latitude at noon;
2) line of position sun & plotting, advancing the latitude at noon in order to get a fix.
They will start at 1400 hours, take about two hours, and will take place at Rosalind’s house in Alcalalí.
Please note that celestial (or astro) navigation is only of use to people who will be sailing out of sight of land.

CBYA Training Officer
Philip Moreland is a new member of the CBYA. He owns a Jeanneau 49DS, named Eliza Fernley III, moored at Marina de Dénia, and which is in beautiful condition.
Last week Debby & Bruce Cowen, and Peter Steenhuis joined him for a not ‘so hard afternoon at sea!’
This was another really super day’s sailing, with good company, good weather and GREAT challenging winds.
In fact, the whole day proved quite ‘Challenging’!!
We all met as normal 10am at Bar Due. Due to a great response, we had nine crew members for this trip. Possibly at least two too many in truth, so a lesson learnt there. (Please note numbers may need to be restricted in the future.)
What a great day! We had a good taste of all wind conditions, and a great sail overall.
The crew comprised:
1st Mate – Jim Cooper
John Van Rooijen
Plus myself – skipper
Note: Sadly Helen Harrild had to withdraw due to ill health.
After meeting at 10am at Marina de Dénia, completing brief introductions, and finding out each crew members relative sailing/boating experience, we boarded our charter boat for the day. A very nice Jeanneau 39i.
We had a full house at the Jávea Players Studio theatre on Monday 7th October, over 60 attendees, for Part I of Rosalind Miranda’s excellent presentation about her Asia Pacific cruise.
Rosalind told us about her adventures when she bravely sailed from Fiji to China. What came across was extraordinary bravery, confidence, determination, and practical application of intelligence tempered by a sense of humour and humility.
Her presentation describes her adventures and experiences in sailing her 8 metre yacht Uhuru from Fiji to Hong Kong, via the New Hebrides (now Vanuatu), to the Solomon Islands, which was then the British Solomon Islands, to Papua New Guinea, to Truk in the Carolines, Saipan in the Marianas, Japan and Taiwan.
There were so many stories to tell that we only got as far as the Solomon Islands!! Luckily, a second session has been organised for Monday 25th November to take us on to Hong Kong. Look out for details nearer the date. Unmissable!!
The audience was flabberghasted at her courage, especially given that she bought the tiny yacht and subsequently learnt to sail her! There were no luxuries: no electricity, running water or navigational aids. Along the way she learnt astral navigation, about which she has written a book [a copy of which has been donated to the CBYA Library]!
More than 20 members enjoyed the tapas at Restaurante Area 1 after the event.
Many thanks Rosalind!
CBYA Cruiser Charter Days
Sun Odyssey 439
From now until next summer, the CBYA will be chartering their own yacht each month from Náutica Corcho, Dénia Marina, instead of using a member’s boat. This will be either a Jeaneau Sun Odyssey 37, 42 or 44, dependent on the number of crew wanting to sail.
You can view their superb boats, and get a taste for it, by clicking HERE.
A minimum of six crew is required, no maximum – the more people, the bigger the boat we can charter.
Participation is encouraged, but sailing experience is NOT essential, as there will be others on board qualified to sail the boat.
The format on the day in brief:
We meet at the marina by 10.00 hrs for a coffee and the briefing.
Departing the berth, we will sail where the wind can take us, enjoy the experience, the sea and the scenery.
Returning to the berth between 17.00 and 18.00 hrs.
Bring some lunch, water, coffee, beers, etc., (as we are using a charter boat the galley is out of bounds).
Non-marking deck shoes are required, also suitable clothing for the day, and a water proof jacket, in case the weather changes.
The cost is just €60 per head.
Payable in advance, direct to the CBYA. Details will be sent out separately later.
All are welcome, friends or family.
So don’t delay, contact the organizer, Graham Hustler, now by clicking HERE to book, or for further details.
You can also check on the CBYA calendar for future charter dates.
