Hi,
Are there any watches where you can freeze the time (the actual time, not the time on a stopwatch) until you've had a chance to to log it and calculate your position - and then un-pause the time so the watch returns to the now current time? Cheers, Fred. |

Yes, it's called a memory. If you are competent enough to sail/boat, use logs, and calculate your position, you ought to be able to remember a time count on a watch for a few minutes while you calculate. If not, just write down the time first before you begin calculating your position. I fail to see the need for a watch that you can pause. |

Hi Fred,
I do not know of a watch that does that, but you could soon write a small program for a pocket computer that did just that. I wrote a program for Astro Navigation that included just that function, years ago. It ran on the old Psion Organiser II pocket computer, which you can pick a working model of up for 5 pounds or less. Regards, Mike "Fred Finisterre" wrote in message ...

Regards, Mike I don't know about Psions, but most hand held computers don't have sufficiently accurate clocks for navigation purposes. My Sony Clie (PalmOS) is only good to a few minutes. Paul |

The usual technique is to start the stopwatch at some known time prior to
taking the sight (say, on the hour), then stop it at the time of the sight. Most navigational watches include the features you need, but at a price. http://www.sailgb.com/p/suunto_x9/ -- "Fred Finisterre" wrote in message ...

For Christmas, from Santa, I received a Casio G-shock model #2608 watch
that has a "Time Recorder" feature that allows me to record and store, at the touch of one of the buttons, up to 30 records of the current time (month, day, hour, minute, second). It is solar-rechargeble, displays world time, also has the usual stopwatch and alarm, but the really outstanding feature is that every day in the early AM it receives a signal from the cesium atomic clock in Fort Collins, CO to synchronize the time. You have to be within 2000 miles of Fort Collins for this feature to work. Bob "Fred Finisterre" wrote in message ...

Yes, try looking through the Casio site. There are a nice range of solar-powered radio-controlled watches from Casio, that also have the feature you want.

In track and field their called digital stop watches.
GPS would be easier except the qualifying word was "Yachtsman" not wannabe. "Fred Finisterre" wrote in message ...

Cheers, Fred. you can achieve the same effect with a stopwatch - start it at a known time - stop it when you take your sight and do the math to work out the time you stopped it. John |
