If you own a sextant, recall that if the “vertical angle” between the light and the water below the base of the lighthouse is θ’, and the lighthouse is “h” metres high, you are d = 1.85*h/θ miles from the light. In the present case, if the vertical angle is less than 180’

(3°), you will be clear of the rock.

## Just set your

sextant to 3°, and observe the lighthouse time, without leaving the cockpit or your plotting anything. If you’re too close, it’s obvious, and you can steer off a bit.

If you don’t own a sextant, but can steer a reasonably straight course, you can take a bearing on the light with your hand-bearing compass so you know the angle between the light and your course (“relative angle”). Go along for a known distance (just read your log, or use the 60D = ST formula we all know), and then take a second bearing, such that the distance you’ve traveled between observations is equal to the distance you will be from the light when it’s abeam. You’ll know at once if you’re safe, or need to turn, and you never leave the cockpit or your guests, neither need you plot anything. What angles to use? Any two angles will do, provided the two relative angles satisfy the relation: cot (Rel. Ang. 1) – cot(Rel. Ang. 2) = 1. The AP book likes 26.5° and 45° for the two angles. The Piloting book gives several other angle pairs. My own favourite pair of angles is 20° and 30°; since these are simple enough that I can remember them. For more information, check out our Piloting and AP courses, where you’ll pick up lots of great stuff on this and other “running fix” techniques! See you in class!

# Message From the Helm

As another training year comes to an end I would like to take the opportunity to congratulate this year’s graduates. We hope to see all of you at the Graduation and AGM on June 1st at the Armdale Yacht Club. My thanks go to our dedicated instructors, volunteers and the Halifax Bridge members for all the great help and support they have provided over the past year.

Halifax Squadron had a very successful year in all respects. We’ve had excellent attendance at all of our courses that were presented at a variety of venues such as RNSYS, AYC, Halifax Grammar School, SMSC, and Halifax West High School. We are trying

to find locations that best serve our students! New technology, such as an LCD projector and a variety of computer software, has made useful teaching aids, permitting clearer presentations in class.

Your Bridge has taken a proactive role in helping to make the squadron more efficient and increasing communication with our membership. Printing the Foghorn in colour has increased its visibility. It is now more useful as a communication tool that has increased our interaction with local marine retail outlets and yacht clubs. We have a fully overhauled website site that’s kept current with the latest news on courses and activities. Our financial accounting has been modernized with current accounting software that helps us to manage costs and budgets. Over the past year we have hosted a number of social events with interesting speakers. Our Public Relations Officer, Maureen McInerney, has done a great job promoting our courses and squadron activities. These initiatives, all completed in the past year, required a lot of hard work and dedicated support from the volunteers of your Bridge.

Our membership has grown to over 400 members. This is the largest it has ever been. This year we have tried to increase our electronic communication with members. Email is a fast and cheap method of communication, however, to date, only about 50% of our membership have provided our Membership Officer with their e-mail address. The use of e-mail would assist in providing timely updates and announcements to you. Your help in providing us with your current e-mail address would be greatly appreciated. Send your email address to Sarah-Jane Raine at rosali@ns.sympatico.ca.

Of course, one of the best ways of promotion is through word of mouth. Many people who have taken courses with CPS have initially heard about CPS through a friend or other contact. We hope that your experience with CPS Halifax Squadron has been a good one and that you will encourage your friends to consider learning more about boating safety, navigation and equipment. We welcome anybody who enjoys boating and has an interest in training others to become safe boaters to volunteer with our organization. There are always activities that could benefit from your help.

I look forward to seeing both grads and general membership at the upcoming graduation ceremony. We will be there to answer any questions you have about CPS, the new courses being offered and any feedback you may have about this year’s courses. It will be a fun event and a time to meet with old and

new friends. Hope to see you there!
