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

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!

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

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

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

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

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

Converting Relative Bearings  Ship heading 045°T, relative bearing 090°, true bearing = 135°. 045 TH 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 RB 150 = 445 – 360 = CB 085.  Compass heading (CH) + RB = CB  Magnetic heading (MH) + RB = MB  True heading (TH) + RB = TB (true bearing)

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  MH 307 CH 356 TH 007 MH 123 TH 267  RB 045 RB 330 RB 355 RB 098 RB 145

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

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

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

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

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.

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

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.
