Logging The Details
by The First Mate

Since this article contains the irreverence, (with regard to sailing matters considered sacred and deadly serious by many, including some who sail very little if at all,) for which we are fast becoming infamous, this preface is by way of a health warning: 

Reading The Next Sentence May Cause Your Blood Pressure To Rise Intolerably

You have been warned...

We have the usual dreary log book to satisfy any official who has been given the divine right, by some new edict or other, to know whence we come and how we got to wherever we are. 

In addition, we keep a Companion Log for all that it would be nice to record but would clutter the official effort. 

In the Drear Log we put an asterisk anywhere there is something to be expanded upon and the Companion Log takes the overflow. Looking back over the one for our schooner's 27th Atlantic crossing, it was fun to see all the doodles that had been made - suggesting improvements to things: a description of a peculiarly complex card game a Croatian chap had tried to teach us; descriptions of the fish that had escaped us and the lures they had taken with them; and, very usefully, a reminder of all the things that had been fixed temporarily and would need fixing properly once we reached our destination. 

We were surprised to find we had completely forgotten one or two repairs because things were no longer causing annoyance and might have been overlooked were it not for the Companion Log. 

Unfortunately, on her 28th crossing, there wasn't much time for log-keeping of any description - there's only so much two of you can manage in some situations - but what made me laugh, after we arrived in the Azores was an official, upon discovering that we neither use waypoints nor record our track on the GPS (we've never even thought about doing it, to be honest) saying "Well how could you have got here then?" with a shocked expression. 

"Same way as your pal Columbus" we said, but he couldn't see what we thought was so funny. He was right, of course. Columbus may have falsified his logs but at least there was something written in them for every day!

In case you're thinking we're completely mad, we do plot our position on a paper chart at frequent intervals but often that is all there's time, or in our opinion, need, for, when out in the middle of an ocean. Near land we are as log-conscious as anyone with half a brain should be.

 

NAVIGATION NOTICE BOARD

 

Thanks to Chris Price for giving us this one: Tides Online: Offering near real-time tidal and storm surge water level observation data and plots.

Advanced Coastal Navigation Course, free and online: http://web.inter.nl.net/users/SAILING_Greece/navcourse0.html

 

 

Here's what sounds like a great idea: waterproof charts!

  We are grateful to Ed Paynes for furnishing us with extensive details of the following navigation software program:  
 

OziExplorer

OziExplorer is a shareware program, for GPS Navigation. There is a restricted, free, demo version, to enable you to see whether the program suits your purposes.  

To register, and thus gain access to the fully operational program, seems to cost between US$65 and $75. 

Tools are included that enable you to calibrate your own home-produced charts in the same manner as the Yeoman system does with paper charts. You produce charts for the program by scanning in existing charts which you then set up in OziExplorer. 

One of the benefits of this system which may not be immediately apparent, is that you acquire the paper chart, which any sensible sailor would have aboard and use (regardless of whichever navigation software system were chosen), against the possibility of electronic failure, and that same chart serves for electronic use too, so that you are not committed to acquiring charts on CD in addition to the paper ones. 

The system was originally designed for use on land and the demo chart that comes with the trial version is more of a map than a chart but don't let that put you off taking a good look at how the system works.

Asking around, we found that people who had taken the time to get acquainted with this software seemed to speak very highly of it.

 

 
  'Seaweed' also answered our call for information on navigation software:

"I use SeaPro 2000 and have found it to be excellent.  The system can use ARCS, BSB or Livecharts. 

I prefer ARCS charts although I have found them to be expensive. There has been a price reduction, which was a good thing but the price was not dropped low enough, in my opinion.  SeaPro have world wide coverage and provide an excellent service.

I have used the system for nearly 3 years and have no complaints."

Our thanks to 'Seaweed' for responding to our request.

 
 

Thanks to Chris Price for telling us about 
this pair of websites:

will take you to details of a GPS PC card, handy for those with a laptop aboard who wish to be able to connect a GPS to it. The price seems to be somewhere around US$ 640 on average and you may like to take a look at the website that offers this product online:

Gulf Stream & Oceanic Information
Website reviews provided by Chris Price

http://www.erols.com/gulfstrm is the  site of "Gulf Stream Guru" Jenifer Clark. Here you can order Gulf Stream charts and other services she provides. 

http://fermi.jhuapl.edu/avhrr
Excellent site by Johns Hopkins University. 
High resolution, realtime, false color, NOAA polar-orbiting infrared satellite images, covering the entire East Coast and Gulf of Mexico. Also 3 and 7 day composites available, archive available for at least 3 months. 

http://marine.rutgers.edu/mrs
Another excellent site, from Rutgers University. Realtime false color imagery covering large areas and covering 3 degree squares, too. Also, visible data and drifting buoy tracks. You can determine drifter velocities by computing distance divided by time. This is particularly useful information if the buoy is in an eddy or in the Gulf Stream. 

 
We'd love to hear from you - we are interested in what you have to say, whether as a user of navigation equipment, a supplier, an experienced navigator or a total novice...
