8. ORD-11b Explain the duties of a lookout and demonstrate how to report objects in view and wind directions with respect to the vessel

9. Lookout Duties • Rules of the Road require to keep good lookout • Stationed where there is the best visibility • Ability to communicate with helm / bridge • In the bow, must face helm & shout, insure the call is acknowledged • Stern lookout in fog or reverse • Anchor lookout may be needed • Good vision – wear glasses!

10. What to Report • Relative bearing, course and speed of vessels that may affect your vessel • Relative bearing not changing = collision course • ATONs, channels, obstructions, hazards • A crab pot may be reportable in your vessel • Relative wind direction and strength

11. ORD-11c c. Name relative bearings expressed in degrees

12. Relative Bearings • Referenced to the bow of the boat • Bow is 000°, starboard beam is 090°, stern is 180°, port beam is 270°

13. Clock System Bearings • 360° ÷ 12 = 30° per clock number • 030, 060, 090, 120, 150, 180, 210, 240, 270, 300, 330, 360 • Interpolate in between as needed

14. Pelorus • Provides precise bearings • Sighting bars • Reads relative bearing • Some have scales to convert to true / mag bearings

15. Converting Relative Bearings • Ship heading 045°T, relative bearing 090°, true bearing = 135°. 045 TH + 090 RB = 135 TB • Always add heading (TH, MH, CH) to relative bearing (RB) to get bearing (TB, MB, CB) • If total is greater than 360, subtract 360. CH 295 + RB 150 = 445 – 360 = CB 085. • Compass heading (CH) + RB = CB • Magnetic heading (MH) + RB = MB • True heading (TH) + RB = TB (true bearing)

16. Practice Problems • TH 037 CH 128 MH 205 TH 268 CH 333 • RB 128 RB 222 RB 027 RB 097 RB 175 • TB 165 CB 350 MB 232 TB 365 - 360 005 • MH 307 CH 356 TH 007 MH 123 TH 267 • RB 045 RB 330 RB 355 RB 098 RB 145

17. ORD-11d d. While underway, serve as a lookout for one watch

18. ORD-11e e. Demonstrate the use of wheel or helm commands found in the Sea Scout Manual

19. Wheel or Helm Orders • Commands are right / left rudder, or heading • Right rudder turns boat right • Boats vary in how much rudder is available • Big boats may have less rudder available • Rudder over 45° slows boat, not faster turn • Rudder angle indicator, or tiller, shows position • Middle size wheel boats may have no indicator

20. Rudder Commands (1) • RIGHT FULL RUDDER = max deflection right • RUDDER AMIDSHIPS = center the rudder • RUDDER 15° RIGHT = rudder 15° right & hold it • EASE THE RUDDER = start to move it back • EASE TO 10° = move it back to 10° • HANDSOMELY = slowly • MEET HER = slow down the swing of the bow

21. Rudder Commands (2) • NOTHING TO THE RIGHT = cannot go to the right, but can go a little bit left of heading • SHIFT YOUR RUDDER = put the rudder the same amount on the other side • MIND YOUR RUDDER = 1) stand by for an order, 2) pay better attention to your steering • Repeat any order. When you have accomplished it, repeat it again to show compliance.

22. Heading Commands • STEADY AS YOU GO = hold your heading • STEER HEADING 045° = turn to and hold heading 045°. • STEER COURSE 045° = maintain the course line on the chartplotter • Wind and waves will buffet the ship. You can anticipate and hold heading closer. • Look on far shore (or a low star) for a line-up point that matches your compass, aim for it

23. ORD-11f f. Supervise and contribute to the cruise log for three days of cruising (one cruise or a combination of day cruises). Submit the cruise logs to your skipper.
