Notes for members of the Boating Course – Middlesex Middle School – January 2010
This is posting # 6– To be posted following the sisth class, Wednesday, March 3, 2010
The course exam is scheduled for Wednesday, March 10 - 7:00 pm at Middlesex Middle School.
IF YOU ARE UNABLE TO ATTEND THE SCHEDULED EXAM - please send an e-mail to dsps@optonline.net to receive information about a "make-up" exam time. The "make-up" exam will be scheduled to accommodate as many students as possible - it will probably be scheduled for one week's delay: Wednesday March 17 - at a location to be determined.
Bring the yellow survey form, and Squadron Membership Form (optional !) with you and turn them in prior to taking exam.
You do not need to bring your chart, textbook or plotting equipment - just a pencil for marking the exam form.
The exam will be 50 multiple choice questions. Please plan to wait for the exam to be graded. You will receive your Course Diploma, and instructions as to how to apply for the State Safe Boating Certificate, within a relatively short time after you turn in your exam.
Some light refreshments will be available while you are waiting for your exam to be graded. Representatives of the Darien Sail & Power Squadron will be available to answer questions about further opportunities for boating education.

4. NO
5. Greater
CLASS 2 – EXERCISE # 5
1. 6.5 NM
2. 78 minutes 60 * 6.5 / 5 = 78
3. 21 minutes 60 * 6.5 / 18.5 = 21
4. 5.2 NM 52 MIN
328 degrees Magnetic
1.9 NM
19 MIN
Cable & Anchor Reef
1.3 NM 13 MIN
2.2 NM 22 MIN
2 minutes
5. N4
115 to clear N6, and then 145 to get to N8 - definitely NOT 133 which would take you into a dangerous area South of N6
6. 3.1 NM 1019 115 degrees Magnetic to Smith Reef, then 80 degrees Magnetic to Greens Ledge – do NOT take the straight line route

CHARTWORK # 2 – HOMEWORK # 2 – The Voyage of the “Vivid Imagination”
You are responsible
Yes – as always on a long trip
1.7 NM
1536 1512 60 * D = S* T D = 13.0 S = 5 T = ? T = 156 minutes if D = 2, T = 24, so subtract 24 from 1536 = 1512
Port (left)
Tug & Barge 13 then 16 I am a sailboat near 11B – do you have me on your radar?
I have changed course to pass port-to-port, do you still see me on radar?
Resume course and speed – making adjustments in DR track
Make circle – create a wake – (if necessary shut engine off, ) and listen for wave to rock the bell

CLASS 1 – EXERCISE # 1
4. Feet
5. 20’ in the main chart. On the detailed charts on the back: it varies. 10’ on Port Jeff chart, 6’ on the Northport chart – so be careful as to what each chart shows.
6. Yes, 30’ 60’
7. Wrecks South-West of Darien’s Long Neck Point, and South of Greenwich. No.

CHART-WORK #2 – HOMEWORK # 2
The Voyage of the “ Vivid Imagination ”
You have agreed to return the sailboat “ Vivid Imagination ” from Port Jefferson to it's home port of Darien . The owner, your friend, has been called away on business and could not bring the boat back herself. The boat is in excellent condition, with a working radio, GPS, depth finder, and all of the standard equipment that is required. If your friend had failed to provide the required equipment, say, proper flares, and you were then stopped by the Coast Guard for a safety inspection, who would be responsible for the infraction ? _________
The new GPS is working, yet you have been warned that it has been “a little flaky.” Will you post a DR track on the charts, just in case the GPS fails you on the trip? ________
There was a thick fog yesterday, but today it is only hazy. From the dock at Port Jeff you can just see the tower at the entrance (FL R 4 26ft “2A”) How far away is it ? _________ (use the detail chart on the back of the main chart to answer this question).
Next, you lay out a course from RW “PJ” to the “11B” Gong near Cable and Anchor Reef. Departing RW ”PJ” at 1300 with no breeze, you proceed under power, at 5 knots. What is your computed ETA at the “11B” Gong north of Eatons Neck? __________ What time should you begin to look for the Gong, if you assume it will be visible at 2 miles? _______
After an hour on course, you plot your DR and then take a little nap, leaving the helm to the crew. An hour later the crew wakes you, reporting the onset of thick fog. They have put up the radar reflector, donned PFD's and taken a quick fix from the GPS (although they did not get all the numbers, they jotted down 40-59 and 73-20 on the flap of Fig Newton box). You quickly interpret this as a Lat/Long position and see that the plot is somewhat south of your intended course. Your crackerjack crew reports: “Rather than steering the course you had given us (288 Mag) we've been steering more towards Eaton's Neck, and not paying too much attention until the fog started to come in.” UH OH! The GPS has just gone on the blink and now shows all “9's.” O.K. Your goal is still to get to “11B.” You remember an excellent way to find it: you notice that “11B” is on the 60' depth contour line, so you decide to continue on the same course (288 Mag) until you hit the 60' sounding line, and then turn to starboard and follow the 60' line north to the “11B” Gong. While running along the 60' sounding line, when the soundings show more than 60' you turn to __________
Having found “11B” you change course towards “R28C.” Immediately, you hear a major league, loud, and close “one long, two short” blasts forward and to starboard. It sounds “larger than a sailboat. What IS it? __________ What channel on the VHF do you use first to call this other vessel? __________ What do you say?__________
After your conversation with the other vessel you decide that you should slow down and turn to Starboard. What do you ask the other vessel? __________
Soon, this large noise maker is off your Port Beam, and then it is heard more and more astern. What do you do now? __________
Eventually, as you arrive in the vicinity of the “R28C” Bell , you do not hear it. What can you do to make the bell sound?_____________
The fog lifts, you see Long Neck Point. It's a good thing to be home with Vivid Imagination !
