Bon Voyage Crawdad

The cold snap, which is the coldest weather I have experienced down here in St Marys seemed to persist longer than forecast, about a week. It has been freezing overnight and most of the mornings, temperature going down to 28 on successive nights. This is nothing compared to what people up North are [...]

The Penguins Have Us

The coooold snap that is freezing us to death is only affecting the Keys a bit, maybe ten degrees less, so 50‘s and 60‘s instead of 60‘s and 70‘s, or 70‘s and 80‘s. The Keys and Bahamas are where to be in the dead of winter.

Happy New Year Chart Wrap Up

It is Sunday, New Year's Eve Day, and I have come down with a cold. My chart work is finished. I can't imagine going outside to work on the hull bottoms now. I may run out of paper towels to sop up my runny nose.

Surrender

When THE COMPUTER GUY was talking to me about running shell scripts to convert old charts I had mentioned I liked to manually crop each chart and save it from the image manipulation program. Every chart. He looked at me funny. The shell scripts are ways to do a lot of that manual data processing and [...]

Sir, Render

The procedure to convert old electronic charts in the tiled .pcx format to charts that newer nav programs can use involves bulk processing with shell scripts. The shell scripts I needed to use are located in a compressed archive called pcx2tif.

A Walk in the Park

I had a couple of negative shopping experiences for the holiday season, both involved long waits for ordinary products. I wasn’t looking for quick shipping this time of year, but please, Amazon waited a week to finally ship a box of grinding discs and a roll of Gorilla tape. And that is just to ship [...]

Capn Andy/chilly winter
Although the primary goal of this blog was to inform boatbuilders who are contemplating a Wharram build, it has become a repository of any information I want to save for myself and anyone who wants it. So, along with the Wharram boatbuilding is Wharram sailing, and other boat sailing, and some other things relating to sailing, like electronic navigation, or outrigger sailing canoes. Also we are in the Saint Marys Boat Services boatyard for the time being and there is some information about that for those DIY’ers who might come this way.
.
I seem to keep finding ways to drag out my projects, mostly by initiating new projects that will only take 20 minutes or so. They do not take 20 minutes or so.
.
The boatyard owner, chief crane operator, and boatyard manager was unavailable a while back, so a desperate DIY’er brought his boat right to the travel lift well and asked to talk to Rocky, the owner, etc. True, he had his phone turned off, too busy to get more business, but he had to take this request, he came to the well and asked the boater how long he would be here. The answer was, about 2 months or so. Exactly what I told Rocky when I came up 2 years ago. About 2 months or so. So Rocky replies to this guy, we have some here who came in for two months and have been here two years, looking right at me. I pipe up but I’ve gotten 2 months worth of work done...
.
It is that awkward time of year when we would be in the Bahamas or the Keys somehow, yet we have not organized things well and we are in the boatyard still and winter is sneaking in with chilly, even frozen, nights. The cool temperatures are great for physical (yuk) labor, but bad for epoxy repairs. So we will grind and prepare for an epoxy fest when it gets warmer.
.
There is also electronic work to be done on the navigation charts that won’t load into OpenCPN. These are in a format so obtuse that it is a major effort to convert a single chart to the BSB format that OpenCPN likes. I think we have about 4,000 charts that can be converted, now get to it, ha ha. No way. I’m serious, there are at least 4 folders on the computer of unusable charts, covering the Bahamas, Caribbean, Central America, and Mexico. I am sure they are outdated, but normally charts need to be updated, things are always changing, new wrecks are wrecked, wind farms, oil platforms, shifting sands, FAD’s (fish aggregation devices), and who knows what else that comes along as an obstacle to the sailboat on its way.
.
Our really big problem is getting those old maps into usable form. I remember running into this problem quite a while ago and ended up using two different nav programs, one used the BSB charts that OpenCPN likes, and the other would use the other non-usable charts, or so I thought. It turned out that all was not black and white. The BSB charts, like the current free downloadable NOAA charts, are in the white end of the spectrum. Old MapTech charts that use .pcx image tiles in a convoluted scheme are at the black end of the spectrum. In the middle gray area are charts that can be converted to the white. Our really big problem charts are those in the black region, the old MapTech charts.
.
I guess what happened a long while ago and prompted me to sign on the face of a DVD “Caribbean Charts, run VNS” was the fact that VNS, Visual Navigation Suite, an old navigation software, ran some Bahamas charts that I thought were the blackies, the old MapTech’s. I am not sure what really happened, maybe the folder of charts that did install in VNS weren’t old MapTech at all, just some old BSB charts. Or maybe they were a folder of charts that I converted using some old software hacks that are now called shell scripts. It doesn’t matter now, because those old charts also run fine on OpenCPN, so VNS doesn’t have some magic power to load and install old MapTech charts.
.
There is an old nav program called SeaClear and it has an associated program called MapCal. These two programs can make any image file function as a chart. It needs to be calibrated by MapCal so that SeaClear can have latitude and longitude to put the image on the virtual globe. I remember having success with this one winter day long ago. Now things are more stringent. The process is more convoluted.
.
I claim to be a math and science kind of guy, but the real mathematicians are a breed apart. It’s like music and musicians, the real musicians are in their own world apart. You can work out the chords of a song and learn to sing, but they could do that from day one. So it is with the mathematics. We all count the tiles in the ceiling at the dentist’s office, but they have been counting everything since day one.
.
My work on the problem charts was disastrous. I was using shell scripts to try to batch convert folders of charts. Not only did it not work, when I edited the shell script, it ran and deleted itself and thankfully crashed before it deleted all the charts I was trying to convert.
.
When one is desperate, one submits to learning, and so I began to try to learn a new language, and the online learning site was from someone in India whose English was cluttering the learning process. I found out that maybe he was using a voice to text program that faithfully transcribed what he was saying phonetically and then he was using spellcheck that allowed logically correct English words through, but the end result was a word like tell came out as tail.
.
Since the shell script language I was learning was computerese, the word tail seemed OK, tail meant it was at the end. He was saying tell, like you could tell your computer to do something, maybe he was. So obstacles are created.
.
But we are in a boatyard with paint dust and nasty looking blokes that have ear guards, eye guards, paint dust patterns on their faces, nose guards with filters, and heavy machinery, noisy, but no one can hear them, beeping sounds from backing up, toilets that are stopped up with coffee filters that someone saw fit to flush down, dogs sniffing and barking, looking for food, concerned boater’s wives chattering to add to the din, and you wonder why the old boater is deaf or pretends to be...
.
I ride around on my old Serotta bicycle that has seen better days and I pretend to be deaf. Blind happens at night when I crash into a large wood block. Even in the daylight I cringe a bit at the memory of that crash, whirling around the yard on my way. It is still the best way to get around, finding your parts at the boatyard office, not in my pants as one of the girls suggested, and getting to the bathroom that is not yet occupied before anyone else can.
.
I roll up to the north end of the yard where my boat is strategically located near the edge of the gulag, a rough dirt road separating me from the drainage ditch that is probably the border line, and on the other side is a residence who must wonder about the gulag. As I come in there I see the travel lift, a big machine that can lift a boat, lifting the skipper’s boat, he has sold it, and now it will go off to the well to be launched and swim with a new owner. I have to stop, there is no where to go, and the skipper is talking to a computer fellow who is also a fellow yardbird. Well it’s goodby then, send me a postcard, says the computer fellow, and the skipper says I will send you one, but not to him, he says, pointing to me. Ah, what a relationship. We have sailed many hundreds of miles and got along through those things that can happen when you are a nit in nature’s maelstrom, he has my sense of humor I would say or maybe I taught him something. He taught me a lot about how to manage a boat before you get into harm’s way. I can dish out the humor, but when it comes back, I’m a little tearful.
.
I went out with the camera. I know when it is a good time to take pictures. Take pictures when you are feeling good. Keep them. Go back to them when you are not feeling so well.
.
I took pictures of the skipper’s boat. He’s different than me, he works very hard within his perceived rules, his boat is perfect, the new owner will get exactly what is expected. My boat is like the new universe, projects expanding, black holes forming, but I know it well and I don’t want to have to do that again, it will outlive me after I have subjected it and myself to adventure.
.
The computer guy turns out to be THE COMPUTER GUY. The shell scripts that have savaged me are not only old hat to him, but the very thing he used to manage at a major internet service, who I won’t mention, and I can’t mention his name. While talking with him, which made me very happy to hear he can work miracles with this stuff, he gave me the idea that my shell script files had to come from somewhere, since I didn’t write them myself, and the computers I am using are new to me in the last year or so, so I had to either download the scripts from the internet or from some storage media that I probably have, like a CD, DVD, or thumbdrive. Since I couldn’t find them searching the internet, they probably became unavailable on the internet some time ago. They must be from one of my drives or discs. Yes, I found them on a thumbdrive from 2010, we can work from there.
.
The Miata is waiting on a delivery of coolant hoses that I wisely didn’t order from China, but unwisely ordered from Kentucky. The delivery “logistics chain” is in 3 parts, supplier to USPS, USPS to DHL eCommerce, DHL eCommerce back to the USPS, and finally USPS to the North River Marsh. Might as well have come from China.
.
My older daughter was visiting from England, but she was visiting down in Ocala, a long drive away, so I had to rent a car to go there. She is a giving person and offered to drive up here to South Georgia, but after flying all the way from England it wouldn’t be fair.
.
The metropolis of St. Marys has no Starbucks or much of anything else, so car rental is a big deal, they need some lead time to have a car for you and I didn’t give them enough lead time so they didn’t have a car for me. This has happened in the past, and back then they would lease a larger vehicle, but had to honor the rental price that I had requested. So, I ended up a while ago with a large pickup truck, a nice vehicle, and was able to use it to run a few errands moving stuff. This time they had 3 large pickup trucks and one somewhat smaller minivan that could seat maybe 9 adults. I opted for the minivan, silver, and hopefully better gas mileage than the Chevy pickups.
.
This is pickup country, the officer will wave you through the intersection and nod if you are driving a pickup truck, the yardbirds will want to talk about your driving experience and argue about Chevy vs Ford vs Dodge Ram, but if you are driving a Miata, a sissy car, none of those good things will happen. So I may have chosen the wrong vehicle.
.
They gave me a free half tank of gas in a round about way to make up for my not having an economy car, but they charged me ten bucks more for the larger vehicle, although it was 70, yes 70 dollars more per day than the economy car.
.
The drive down to Ocala from the North River Marsh only took about 2 1/2 hours. We were going to try to replicate our photoshoot along the Gunpowder River up in Maryland, and I hoped we could do it at Sholom Park, a place that slaps a fee on commercial photographers, so often that it is used by them. We did the whole park and shot it up, but none of the stark images we got up North were here. It was peaceful, restful, beautiful, but there was no snow, nothing to evoke an elemental solidity, no large cold rocks, it was warmth and softness. My daughter was thankful for that intangible peacefulness that let her unwind. It was good for her.
.
Maybe I’ll make another photo album from the pictures from the park. Here is one, not much to look at, very peaceful though.
