Navigation

Yesterday the Santa Maria celebrated the 518th anniversary of Columbus leaving port (the actual date is tomorrow but special events work better on weekends). Since the event is called "Navigation Day" I brought some of my personal collection of navigational tools and gave some talks on period navigation. At the same time, I've been reading Flint and Silver. A major plot point of this (and of Treasure Island) is that Long John Silver and his crew of pirates do not know how to navigate. This was also a plot point in Captain Blood. This got me thinking about period navigation. What was it that made navigation so difficult?

Any time a ship was out of sight of land it used "dead reckoning." This boils down to keeping careful track of what direction you are going and how fast you are traveling and figuring your position from that. The basic tools were the compass, the sandglass, the traverse board, and the log line (with its own sand glass).

Every half hour the helmsman would turn the glass and put a pin in the traverse board. The traverse board looked like the face of a compass and had eight concentric rings of holes. Each ring corresponded to a turn of the glass and each hole corresponded to a point on the compass. There were 32 points.

At the same time, the ship's speed would be taken with a log line. This was a spool of cord with a piece of wood on one end. The piece of wood would be thrown overboard and it would pull the cord out after it. The cord had knots at regular intervals. A sand glass would be turned. When the sand ran out you would see how many knots had unspooled and mark that on a scale at the bottom of the traverse board.

At the end of a shift, the results would be written on a slate and given to the navigator. He would use this to plot how far the ship had come and which direction and mark it on his charts.

This is where things get complicated. Each chart might have its own scale. Trying to match positions from one chart to another could be difficult.

Any changes in course would affect the accuracy. If the course was changed five minutes into a shift it would still show the same as if it had been changed 25 minutes into the shift.

The effects of currents had to guessed. The only way of measuring a current was to drop a sounding lead into the water and see if the line bowed out some.

The majority of people at that time could add and subtract but not multiply or divide. Some multiplication and division was needed.

There were other tricks that came from instruction or practice. If the bottom was close enough for a sounding, you would put some fresh tallow into a depression in bottom of the sounding lead. This would bring up a little of the bottom. Really detained charts of known waters might include information about the bottom - sandy, gravel, silt, etc. Even if you were out of sight of land, silt meant that a river mouth was near.

You could check your latitude with various instruments that measured the angle of the sun or North Star. There was no way of figuring longitude at sea.

Sailors left all of this to the navigator. Without charts and the logs, there was no way for them to tell anything but the rough direction, anyway. All that mattered to them was not getting lost.

The Black Tot

Yes, that's Black Tot, not Black Spot.

Back in the good old days, British sailors got a daily rum ration called the tot. In fact, from the mid-17th century through the early 18th century, they got two rations of a half pint each per day (for a total of a pint a day). To be sure that the rum was not watered down, they would mix it with gunpowder and try lighting it. It it still lit then it proved that it was still strong. This point was just over 50% alcohol which is why today's 100 proof is 50% alcohol.

In 1740 Admiral Edward Vernon started issuing rum diluted with a quart of water per pint to reduce drunkenness. This mixture, known as grog, may have been named form him. His nickname was "Old Grogram" because of the grogram cloak that he wore.

The tot was gradually reduced to 1/8 pint, once a day by the 20th century.

In 1970, the British Navy decided that even that was too much and abolished the tot. The last tot was issued July 31, 1970, known as Black Tot Day.

Don't feel too bad for the Brits. Their beer ration was increased by one can a day at the same time.

In contrast the American Navy had ended the rum ration September 1, 1862. Instead of beer, the US Sailors got free coffee.

BBC News has more here.

The tot ended before the rum stores were emptied. What was left was saved. If you have some spare cash and a desire for history, you can buy a bottle of official navy rum for 600 pounds. See here for more details.

Early Slops

It's been over a year since I did any research on slops. That time I relied mainly on second-hand sources. A friend at Jamestown asked for justification for slops on the sailors there so I did some original research of my own.

I started with this guy from Gentlemen of Fortune.

They list him as being from 1720. He looks earlier so I looked up the artist. This led to the British Museum. I did an image search on their site and hit gold. This one is Dutch from 1600 and is perfect for my purposes. He is wearing slops, a cassock, and a thrum cap. This is fairly close to what I have worn when doing an early 17th century impression.

 Next are some harbor views from Flanders, from 1647.


All of these have one or more people with some sort of slops. There is also this one. Notice the sailor sitting on the left.

Finally, this site has a woodcut from 1577.

A few points. First, this shows that slops were fairly common from the 16th century and were worn at least into the early 18th century.

I have seen some sites say that they were used as overalls. These etchings do not show any sign that the slops were being worn over breeches. 17th century breeches were very full and would show if they were worn under these slops.

Finally, there are arguments about the bottom of the legs - were they hemmed or not? You can make a strong case either way from these etchings. Some, especially the earliest, looks like they are. The later ones might not be or could have been at one time but the hems are worn.

Grand Encampment 5

Officially we were batteau-men, providing transportation to the British soldiers at an F&I reenactment. This was a major event with hundreds of reenactors and a couple of dozen sutlers.

We were afraid that we would be encamped with the British army. They were a long way from the lake where the boats were so we were not looking forward to that. Fortunately, they created a British Boat Camp beside the lake. This had eight or nine tents and at least fifteen people so we had a mini-event separate from the main event. Not only were we closer to the boats but our camp was a lot cooler than the main British camp. The French and Indian camps were cooler yet since they camped in the trees.

Funny thing - the only groups that bring boats are pirate groups. In addition to our Scioto Pirate group, the Great Lakes River Pirates were there. We know them from Paynetown and they are always fun to be around. At some point people started calling the camp "the pirate camp".

For boats, the River Pirates brought two small boats and two medium boats. I had the Black Sheep which was the largest of the five. The park provided two impressive 30' war canoes and rangers to command them.

All of that was good. Not everything was perfect. The nearest port-o-let was a long way away at the far end of the Sutler's Row. Water had to be fetched from the French camp (although we had plenty of cool drinking water from melting ice).

Months ago, a call went out for boats but the organizers never really planned how to use them. We "flotillas" on both Saturday and Sunday. On Saturday we loaded soldiers into the boats and the canoes, rowed them half-way across the lake then back again. They landed and took a nap under some shade.

On Sunday we decided that the canoes had been under-manned so we had them load the soldiers into one canoe and we acted as escort. Again, we rowed half-way across the lake and back. We were supposed to be met by the rest of the British army but all that showed up was a narrator.

Saturday seemed hotter than is should have - possibly because of the lack of a breeze. There was more wind on Sunday and it felt cooler. The two boats with sails took advantage of the wind.

We took the Black Sheep out rowing both days. On Saturday when we were transporting troops, we managed to load ten people onto it. I wasn't happy with the trim - too much weight forward - but otherwise it worked fine. With two people rowing we were at least as fast as the smaller boats although I think that Firefly would have been faster yet.

In all, we had a good time but I'm not sure that we would do the event again. The heat got to everyone and it was a lot of work just to ferry some soldiers back and forth.

Here are the River Pirates, lurking in the shade.


Here is the Pirate British Boat Camp



And here is the Black Sheep with a full crew and passengers (with me at the tiller).

 

And here's one of the flotilla from the Black Sheep.

Boat Maintenance

I did a little more work on the Black Sheep over the long weekend.

I made a mast, mainly for show, for Put-in-Bay. This worked but the block that the base went into came loose. I glued this back into place and strengthened the join with some wooden pegs.

The thwarts were wrapped with twine to limit wear on the oars. The twine was in poor shape. I re-wrapped some of it and replaced other parts.

I got some pine tar-based finish and applied this to the seats, the rudder, and the thwarts. Nothing makes a boat smell more nautical than some pine tar.

Put-in-Bay Pirate Fest II

For the last few years, some of the bars at Put-in-Bay had a pirate weekend. Last year this was expanded to an official island-wide festival. Mickey and I checked it out and thought it might be nice to come back with a display. He contacted the organizers. things stalled out a few times and we ended up pulling a group of historic pirates together at the last minute. The idea was to add some historic depth to the festivities. A lot of other pirate festivals do the same thing.

Since Put-in-Bay is an island, the first problem is getting there. We brought two boats so the organizers got us passes for the boats and the cars hauling them plus passes for the participants. Everyone put their gear in the boats.

There were a few rough spots. The mayor did not want us camping in the park where we would be setting up so we were camped about two blocks away. That meant more set-up time and more tentage was needed. The organizers planned on providing dinner for us Friday but we were later than expected and the kitchen closed. They still managed to accommodate us with some nice chicken dinners.

On the other hand, the organizers provided many amenities that we were not used to. They gave us a couple of dinners and breakfasts and a local historic hotel let people use their showers. They also provided a golf cart (the most common means of transportation on the island) and they gave everyone T-shirts.

It was a pretty laid-back event. There were no battles so all we had to do was provide the display. The festival also had a costume contest and many of the pirates entered (M.A.d'Dogge won first prize - a trip to the Cayman Islands).

We used the Black Sheep as part of our display. Since is it flat-bottomed, it represented our long-boat. In late afternoon, we launched Firefly and rowed around the harbor. We even threatened the Brig Niagara (we had a musket and most of their guns weren't mounted).

Saturday was pretty warm although a breeze helped during the day. Sunday was outright hot with no breeze until a chain of storms came in. We got caught in a downpour while we were striking camp. That meant bringing home wet canvass but it also cooled everyone off.

The lake was rough because of the storms. The rain had stopped but a lot of spray came over the rail, drenching people - a lot like standing too close to a water ride at a theme park.

In all, the organizers were happy and want us back next year with even more pirates. The participants all enjoyed the experience, also. With luck, we should see this event grow.
