Well, I'm finally filling out the logbook we bought 2 years ago. Mostly to learn HOW at this point (prior to any real trip sailing adventures) AND to force myself to get in the groove. Fortunately I have all sorts of videos from the boats YouTube channel for me to refer to capture the dates/times.

Here's my questions:
1) What does Course Ordered mean? I googled the life out of it and found zero info. Just a few random images that had 3 different bits of info listed - pilotage, wind, and 150. What the heck??
2) And what are Course Over Ground and Speed Over Ground? Assuming its the course we set and how fast we were going over water? But isn't the course we set Course Ordered?

Thanks in advance,
Cap'n Karen

Course ordered is the course you are steering based on the wind direction. COG/SOG are things you'll pull off your chartplotter or hand-held GPS.

..................1) What does Course Ordered mean? ..............2) And what are Course Over Ground and Speed Over Ground?.............
Course ordered is an International Maritime Organisation IMO standard marine communication phrase per page 2 of the first link as I understand:

Course Over Ground is the actual direction of progress of a vessel, between two points, with respect to the surface of the earth. The vessel's heading may differ from the course over ground due to the effects of wind, tide and currents.

Speed Over Ground is the speed of the ship with respect to the ground or any other fixed object such as fixed buoy or island.......it includes the boat's speed adjusted for current.

Yep what those fellers said.:thumbup:

Karen. If you were headed off to the east out of the Chesapeake you would be into blue water. Pretty soon you would be out of sight of land. Then what would you have to tell you in what direction you were headed? Your compass. Would you stay at the helm watching the compass the entire voyage? At some point you would fall asleep. When you awake you would want to know (if your memory was a bit foggy) what course should I be on.

"Course Ordered" recorded in your log book would give you the information.

Now if you had crew who take over the helm responsibility and were not awake when the course was set, when they start their watch, they can go to the log book and check what is the course to follow during the watch. The "Course Ordered" by Cap'n Karen.

Keep in mind that if you are bay sailing or where you will change course frequently, entering the Course Ordered and the Course Made/SOG would not only be tedious but a waste of paper IMHO. Your log book will be filled up very quickly.with info that is of almost no practical value later. In those cases it may be more appropriate to log your intended destination and pertinent information. The following is an example. Full sentences are not required nor desired. Note the main things that are important to the transit in your log. If its a day sail to and from your home slip, it may just be underway time, engine hours, who is onboard, weather, interesting sitings (dolphins, etc.), boat performance issues if any, time of arrival and ending engine hours.

Here is a hypothetical long entry for a transit offshore from Beaufort Yacht Club to Savannah GA. I don't enter course info unless it is important since I have to alter course to keep in the channel and adjust for changing currents and winds frequently.

6/23/2020 0930 (1630.6 Eng hrs) Underway from mooring at BYSC with Pat, George and Emma Grace onboard bound for Savannah GA. Motored 1 hr to abeam of MCAS Beaufort fueling pier. Raised Main and Genny Sailed to Buoy 2C then turned SW steering course to make 195T. Off shore. Parthy sunny day Winds variable from the W 8 - 12 kts gusting to 18 kts. 1328 received Coast Guard VHF broadcast of vessel in distress 8 miles due W of our location. Responded to Coast Guard that we were proceeding to the location with all due haste, started engine and motor sailed towards reported location HR.MIN.SEC N HR.MIN.SEC W. After 15 minutes CG notified that vessel had been assisted by a fishing vessel and was no longer in distress. Secured engine and returned to make course good 180T to arrive at Savannah River channel entrance buoy. Saw a pod of dophins alongside and a Right Whale with calf about 400 yds to the west just NW of the Savannah River entrance. Notified Right Whale Watch of siting. 1510 reached Savannah River entrance buoy 4C. Doused sails and motored to Downtown Savannah pier. Strong currents in river. Heavy commercial traffic both inbound and outbound. Stayed to Stbd side just out side of the commercial channel. Narrowly avoided collision with 30 to 35 foot powerboat "Time to Drink" erratically changing course. No response on VHF. 1545 Notified Coast Guard of possible intoxicated boater. Great sail, wonderful weather! Arrived Downtown Savannah River pier 1623 (1632.9 Eng hours)

Its just the way I make log entrys and you are free to do what you want but don't get too hung up on formalities.

On big ships the captain or navigator would order the helmsman to steer a particular course, "Course Ordered". On our small boats since the captain and navigator are probably also the helmsman, it's just whatever course you decide to steer. The log heading is just a fancier way of stating the course. A better term might be "Course Intended" as we rarely end up doing exactly what we intended. Speed over ground and course over ground are the actual speed and direction the boat is currently moving. You need a GPS to get those as the compass and speed log are affected by wind and current and are not displaying your actual speed and direction of travel. Those instruments display Speed Through The Water and Heading which are rarely the same as SOG and COG.
