True Virgins Make Dull Company add Whiskey

If your boat driver’s license has expired “beyond grace”. That means that in order to renew it, you must go back to square one and re- submit all the paperwork, and re-take the dreaded exam. Some folks say it has gotten harder since I took it last century. Anyway, I have been installing a compass in the boat, which prompted some of the schooling from my earlier years to bubble back up. I guess it would be a good thing to write some of it out for practice, since I will be re-taking the test. One thing I learned at sea school and did not forget:

“True Virgins Make Dull Company add Whiskey”

As Father Guido Sarducci, of Saturday Night Live fame would say, “and that’s all-a you need-a to know about-a that”.

OK, but if you are curious or masochistic, read on.

The nautical chart shows True north and Magnetic North on a thing called the “compass rose” (see above photo). It is a circular pattern with the degrees of a circle and a few other things marked on it. Compass roses are put there to help you figure out which way to steer the boat. They are scattered about on the chart in convenient places for quick reference. First, you have to realize there is a difference between true headings and magnetic headings. You might know one, but need to know the other. The Compass Rose shows both.

The North Pole, is located at the axis of the Earth’s rotation, on top of the world. Its direction is known as True North

The Magnetic North Pole, is a different thing entirely, and is located several hundred miles away from the North Pole. At present it lies somewhere inside the arctic circle. A magnetic compass only points to the magnetic north Pole.

The Variation is the the difference in degrees between True North’s bearing from an observer, say a sea traveler, and what a magnetic compass would point to- the Magnetic North Pole. My brain hurts already.

A Magnetic compass will always point to whichever direction the magnetic pole is in. However, it will only point towards True North, if and only when the North Pole happens to line up with the Magnetic North Pole. It could even point to a southerly direction. For instance, If a traveling person was way up in the arctic, and happened to be exactly between the North Pole and the Magnetic Pole, his magnetic compass would point to the Magnetic Pole- due South! You can see this with an orange or a tennis ball or something, and a couple of pins. The Variation for the travelers location in that rare case would be 180 degrees. To find true north, he would add 180 degrees, (the variation) to his magnetic compass heading.

The Variation of a given area on the chart, is printed on the chart inside the compass rose. It also “varies”, depending on where you happen to be on the Earths surface, in relation to these two poles. To make matters even more complex, the variation changes from year to year, in small increments, because the magnetic north pole and the magnetic field of the earth wanders around. The Magnetic North Pole is at the axis of the earths magnetic field, where it exits the Earth in the Northern Hemisphere, and it is not fixed in one place like the True North Pole (the axis of the earth’s rotation) is. The magnetic pole is affected by the Iron composition of the Earth’s interior, which moves around because the Earth’s core is liquid below and the Earths crust floats on top of it. In geologic history, the magnetic poles have even flipped. That would be a real calamity if that happened again, which it probably will ( and if it does, Virgins will no longer be dull company).

So, for example, the compass rose on your chart might have something printed in it like “Variation 3 deg West, annual increase 5’, 1999’ “ . The annual increase is the amount of change, measured in degrees, based on past history, of the actual physical location on the Earth of the Magnetic North Pole, each year, since 1999. Now, this is where the “add whiskey” comes in.

True Variation Magnetic Deviation Compass add Westerly

So, moving left to right, TVMDC, just like it reads, you always add (+) westerly. If the Variation is 3 deg W, you add that to the true heading to find the magnetic heading, OR, now get this, if you are reading it right to left, i.e. Magnetic to True, you would SUBTRACT the westerly variation, so if your magnetic reading is, say, 000 deg., and you want to know where true North is, then subtracting 3 deg, would give you 357 deg- the bearing of True North.

Stated differently, the “Variation”, is a number that is applied to the True heading to find the magnetic heading, or applied to the magnetic heading to find the true heading. If you know two, you can find the third with this formula. Add westerly variation going left to right, subtract Easterly variation, going left to right. OR subtract westerly variation going right to left, ADD easterly variation going right to left. The annual increase of the Variation mentioned above should also be tallied up and applied to the number. If the annual increase is 5’ when the chart was printed in 1999 and it is the year 2001, then add 10’ (two years). Year 2005, add 30’, etc. Needless to say it gets trickier and more important as you go north because the relative positions to the observer of the two poles (the Variation) can become more and more pronounced as one gets closer to them.

This stuff is often inconsequential in the real world, but it depends on where you are, and how much the variation is, and how accurate you need to be. A half degree (30’), is negligible in most circumstances on a small boat. You couldn’t physically steer with nearly that much accuracy. A steering error of one degree will put you one mile off course after about 57 miles.

Ready for some whiskey?

Not so fast. What about Deviation?

So, Variation then, is a corrective number applied between True North and Magnetic North, that is used to find the bearing of the other. Using the formula above, all you need are two values and you can calculate the other. Just remember to ADD Westerly, or Subtract Easterly, when moving left to right.,or vice-versa moving right to left in the equation.
The Deviation, is the same kind of number, between the Magnetic and the actual Compass bearing, (TVMDC), that is applied to one, to find the value of the other.

Magnetic compasses are affected by all things ferrous, whether it is the earths iron ore deposits or a sack of nuts and bolts left carelessly on the bridge deck, and also by all things electrical, since electrical fields are really the same as magnetic fields. Depending on the amount of Iron on the boat, and electronics, and their proximity to the compass, any of these can have a disastrous effect on the accuracy of the instrument. In a perfect world, without any local interference, a Magnetic Compass would give a bearing from an observer to the Magnetic North Pole. End of story. But every Boat is different. The distribution of iron implements, fasteners, rigging, chain, radios, etc will uniquely affect the compass. So, just as Variation must be applied to compensate for difference between True North and Magnetic North, Deviation must be applied to compensate for the difference between Magnetic North, i.e., where the compass should be pointing- Magnetic-and where it actually is pointing- Compass due to local interference, or stuff on the boat.

A Deviation table is printed up on a Compass Card, by a compass adjuster, who “swings” the instrument, after it is installed, by tweaking the adjustment screws found on the compass. The screws are supposed to allow the adjuster to calibrate for Deviation, which he usually can do, but sometimes he cannot, and so he prints up a card that shows how much to add or subtract from any given heading. Usually it is divided up into the different points of the compass. It might say for instance, N,+2, NNE-1, NE-0, ENE+1, etc. The closest relevant Deviation number, taken from the Compass card, supplied by the compass adjuster, then is also plugged into the equation TVMDC, and the same rules apply- ADD westerly going left to right SUBTRACT westerly going right to left.SUBTRACT easterly going left to right, ADD easterly going right to left.

Cheers.

Tenderly, he looked into the rushing water, into the transparent green, into the crystal lines of its drawing, so rich in secrets. Bright pearls he saw rising from the deep, quiet bubbles of air floating on the reflecting surface, the blue of the sky being depicted in it. With a thousand eyes, the river looked at him, with green ones, with white ones, with crystal ones, with sky-blue ones. How did he love this water, how did it delight him, how grateful was he to it! In his heart he heard the voice talking, which was newly awaking, and it told him: Love this water! Stay near it! Learn from it! Oh yes, he wanted to learn from it, he wanted to listen to it. He who would understand this water and its secrets, so it seemed to him, would also understand many other things, many secrets, all secrets.
But out of all secrets of the river, he today only saw one, this one touched his soul. He saw: this water ran and ran, incessantly it ran, and was nevertheless always there, was always at all times the same and yet new in every moment! Great be he who would grasp this, understand this! He understood and grasped it not, only felt some idea of it stirring, a distant memory, divine voices.

Brunswick Landing Marina

September 28, 2015 charly Leave a comment

We’ve been holed up since mid- August here in Brunswick. It was the best hurricane plan we could think of. If you look at the map, we are located on the western-most part of the continental US Atlantic coast. The bight formed by the sea coast here gives the area a little more protection, so we seem to have better odds against a direct hit. Not that it doesn’t happen There is a lot of real estate though, between the East River and the open ocean further east. To the southwest, there is Andrews island, which is very high elevation, because it is mostly man made from dredge spoil. We feel reasonably safe here. This year’s storm season has been very tame so far.

The local weather is more tolerable now. Summer afternoon thunderstorms have given way to a general northeasterly flow. The monarchs are beginning to trickle through, and the sunlight is changing hue. So there is hope.

We have at least managed to get out for a few afternoon sails in the last week or so. The East River is wide and protected, with plenty of sea room to hoist the sails as soon as we are clear of the dock. It is a thrill to glide past the town waterfront under sail alone. Catamarans are generally quicker, but we had a humbling experience on Saturday out in the sound, when a production monohull smoked past us on a close reach, as we fiddled with the outhaul and the lazy jacks. There is much to learn yet about tuning and sailing this boat!

A small community of live-aboards tie up here, mostly waiting for cooler weather to head south. Speaking of that, we saw two more spoonbills roosting on quarantine island on Sept 19th, and several more in the Turtle River since then. I had no idea they stayed around this long. We have noticed more of these beautiful pink birds around here this year than I can remember. Last November on the trip to Merritt Island, we didn’t see any until we got into Mosquito Lagoon.

You can see quarantine Island just east of the Sydney Lanier Bridge.It is that small clump of trees on the north side of the Brunswick river. They used to detain inbound sailors there around the turn of the twentieth century. Earlier, it was a popular dumping ground for ship’s ballast stones before taking on cargo in the port. There is a private house there now, and a dock.

Just across the river at the marina is a good level spot to dry out at low tide, and the price is right! We had a pretty good mess of barnacles to scrape off after eleven months. It is hard to believe she has been in the water almost a year.

Arredondo’s Map

August 27, 2015 charly Leave a comment

Gualquini. As it was in mid August 2015

A while back I was poking around looking for stuff about St Simons and stumbled upon Arredondo’s Map. Dated 1737, it is one of the earliest known that shows any detail of the island itself and surrounding area. I am fascinated with it, and have been trying to piece together a picture of Antonio Arredondo ever since. Sent back up from Havana in June 1742 to assist in the Spanish expedition against Georgia, he was a trained engineer, mapmaker, strategist, and did a lot of intelligence gathering for the Crown. You can read his journal of the infamous assault on St Simons that same year.

Arredondo made several maps, some with long-winded titles. This one is called, in English, “Chart for the Entrance of Gualquini, River of St. Simon, Lying in the North Lat. 31 degrees”. The legend at the top right is in Spanish and hard to read in places, but a translation appears along with the map on page 71 of the archived journal linked above. The first thing that jumped out at me was the name the Spanish used for Jekyll Island- “Isla de las Ballenas” or “Island of Whales”. The Right Whale calving ground off the coast here must have been unique enough to have earned the name. Up around where the SSI lighthouse is now, the map shows a small cluster of houses with palm thatched roofs, some earthworks and a small fort with the number and size of the cannons. This was called Gualquini, which started out as an indian village. In the early 1600’s a Spanish mission was built in the vicinity, then Oglethorpe and the English came and built a fort. Still later came the cotton plantations, and finally, then, folks from Baxley started showing up. It has been downhill since.

A couple of roads are shown, very roughly where parts of Demere, Military Trail, and King’s Way roads are now. The map legend notes a “lookout, made of logs”, that appears to have been about where Railroad Avenue was, before Hurricane Donna lopped off that section of the island. The Spanish journals mention the erosion of the beach even way back then.

Down about at what is now Gascoigne bluff and Epworth, it shows a couple of fresh water sources “good, but turbid” and un horno , or oven (I wonder who built it?). From there over to the south, there is a careening ground -a hard, fairly level, sandy beach that dries out at low tide, where boats of all stripes would, and still do, clean and paint their bottoms. There was, and still is, good deep water all the way around the south end of the island, and up the river to the town of Frederica. There was no causeway or bridge then, of course, so a lookout at Frederica could see all the way down the river, and across the sound to Isla de las Ballenas or Jekyll, as Oglethorpe named it.

The Spanish referred to passable inlets as barras. The current bar channel between SSI and Jekyll is referred to as Barra Gualquini, and the inlet into St Andrews sound below Jekyll was called Barra de las Ballenas. Anyway, I think the map is very cool. You can download the file from Hargrett Library’s site and print it out for your living room.

Anyone with any more info on Antonio Arredondo, please e-mail me.

Edit: The indian name is also spelled as Guadalquini here

Roseatte Spoonbills in Jones Creek

August 27, 2015 charly Leave a comment

Local Spoonbill fans probably notice a few birds visiting each summer. Every year around mid July you can spot one from the St Simons Island Causeway, down around Terry Creek. Often when crossing the Brunswick River Bridge on 17 going south I have noticed one or two wading in a tidal pond there just on the other side of the Jekyll Causeway entrance. This is the first year I have seen them in Jones Creek. Hopefully, that is a good sign. For the record, this juvenile was in Jones Creek on August 13, 2015.

We took a few short sails into the Hampton River earlier this summer with Evy and her sister from California, Anne Marie, and with Steve and Janice. They have all been very patient with us as we work out the kinks in all the new gear. Sailing the winding river can be a challenge. We had some great afternoons together! More to come soon.

River of No Return

August 26, 2015 charly Leave a comment

The anchorage in Cocoa is tucked in on the south side of the causeway, close up to the town. It is shallow with no current, good holding, and protection from all points North and West.
That morning there were a handful transients in there, some that had stopped for the night to watch the Orion rocket launch up at Canaveral, a few locals on moorings, and the usual derelict or two. I was there with the Spirit of St Simons and her brand new mast to meet with the local sailmaker, Scott Morgan, and get measured up for a new suit. I tiptoed through the crowd till I found a spot, and eased down the plow. As we rounded up, I took a look around and wondered what my daddy would think.

Seventy five years ago, my folks lived straight across this river on Merritt Island. They rented a farm house right down on the water. It was known as the Winslow place. Dad had an uncle- the bridge tender, who helped him get a construction job over at Patrick AFB. They lived in a shack right out on the bridge. Mamma always told the story about how they would go out there on Sundays and do their laundry, hanging the wet clothes out on the line to dry in the breeze as the traffic rattled past. As I was growing up I heard many stories about this place. Tales of fishing, snakes, mosquitos, oranges, the heat, the diphtheria…

My daddy’s favorite story was about how he rowed all the way across the river to town on Thanksgiving day, and bought a pork loin for dinner. My mother was beside herself. She was terrified of the water, but he loved it. He was fascinated with everything about it -the colors of the open sky, the herons and ibis, the pink clouds of spoonbills.

I was born a few years later, and in a different place. When I was little, my favorite spot was in his lap. He would tell me stories about times past, when he was young and alive, and then he’d serenade me to sleep. He was a big Tennessee Ernie Ford fan:

“ Loaded sixteen Tons, and what do you get… another day older and deeper in debt…”
I could feel the notes as they formed and rose up out of his chest.
“St Peter don’t you ask me cause I cant go…I owe my soul to the company stoooooow….”

My favorite song was what I called “wederee”, or actually, River of No Return. There are a couple of you tube clips of it online, so you can still listen to it if you like. Marilyn Monroe sang it in the movie of the same name, but when I hear Tennessee Ernie Ford sing it I can see my father.

“There is a river, called the river of no return… sometimes its peaceful, sometimes wild and free…I lost my lover, on the River of No return… Waileree Wail erreeheehee. [no return no return].”

Late in the night sometimes I drift into this special place. It is a sanctuary of sorts, that we must all dream of from time to time. It is a place of images where one can re- taste that long dormant sensation of love, security and the blissful ignorance that comes with childhood. When I imagine heaven, it is always some variation of this place. Usually this vision involves water, cypress trees, soda crackers and Vianna sausages, campfires, boats and fish, the smell of spent shotgun shells and Tennessee Ernie Ford.

Its hard to mess up a pork loin. On the boat, I like to keep it simple. I just sear it up a little in my old friend, the cast iron skillet, drop the heat, and cover it. Let it simmer. It doesn’t take long. Put in some vegetables. Anything. Onions of course, but whatever you have. Carrots and potatoes might need par boiling first, unless you cut them up small. It doesn’t matter! If you are anchored up in the Indian River in late November, it is going to be good. A bottle of red wine will make it even better.

The old causeway bridge and the tender’s shack are long gone. The town has changed. The island has changed. The world has changed. But a pork loin with caramelized onions and carrots and red wine under a free and open sky is still as just as good as it ever was.

“ Wail-er -ree Wail-er-reeeeeee. [no return no return no return]”

Trip to Cocoa- First Post

August 26, 2015 charly

The Spirit of St Simons was splashed in the Mccay River mid October of 2014. After that, we motored up to Jones Creek for a quick fit out, and then a few weeks later shoved off for Merrit Island, Fla., to step the mast and get measured up for some sails. My buddies Steve and Jim crewed the trip down. We had a blast! It was below freezing when we left the dock. Motoring down the ICW the whole way, we anchored the first night in the Crooked river in Camden county, the next night at Guana River down below Ponte Vedra. Then we were weathered in for two nights at St Augustine. Fifth night we anchored in Daytona down in the southern end, arriving at Harborside Marina on Merrit island on the next day. The boat makes about six miles an hour under power.
