thread_title: Merger with [[Log_(speed)]]

message: There are multiple un-defined phrases in this, such as "paid out". Perhaps also a picture could help? I'm having trouble understanding the article. Thanks to anybody for cleaning this up for laymen. Word. Zanturaeon 08:42, 21 April 2006 (UTC)
replies: text: See the new external link, it gives instructions on the use of a chip log, although the distance issue and commentary on thirty seconds vs 28 seconds is incorrect.--Vidkun 14:47, 6 September 2006 (UTC)
thread_title: Readability

message: This article seems to assume that the chip log was invented and perfected all in one go.  In fact, the development took time and as such various parameters for its construction and use changed over the years.  For example, both 28 and 30 seconds have been used for timing at different points in history.  The distance between knots depended on the definition of the nautical mile.  This in turn depended on the current state of knowledge of the size of the meridian, since the nautical mile was one minute of arc along such a meridian.  As such, the distance varied and eventually converged on the length mentioned in the article (the comment on the external link at the bottom of the page is misleading as a result - the linked article is using a different point in time, I think). 
The diagram of the chip log does not match the description.

replies: text: I've updated the page to reflect the historical development a bit more and clarify where possible.  I've added two images, one that matches the description of the shape as a quadrant and the other showing the entire kit.Michael Daly 17:29, 2 September 2007 (UTC)
thread_title:  Miscellaneous incorrect info or misunderstandings 

message: There is need for a new stand-alone Log (speed) page, which I am starting in my sandbox.  This page originates from the fact that there are two Wiki pages this one,Chip Log and Pitometer Log that both contain large, overlapping sections on the history of and other technologies of knot logs (and poorly sourced at that) but there is no comprehensive page for the history and development of the knot logs as a whole.
I am combining the extraneous material from those two pages into one new page, organizing it into sections, linking back to these two pages, providing sources, in-line citations as best I can.  I plan to remove that extraneous material from this page and the Pitometer Log pages when I am done.  Take a look at what I've got so far in my Sandbox and let me know what I can do to improve it.  In particular I need help from anyone who might know more about the subject than me who has access to some high quality sources for some of these factoids, or want to start hacking away at it.

thread_title:  Need for a new article 'Log (speed)' 

message: Is a patent log a device for measuring speed, or distance?  The description I'm familiar with is that it's like an odometer (as the article already says).  In other words, it counts revolutions of the rotor, and the displayed value is proportional to distance traveled and NOT in any way a direct indication of speed.  This is in fact a useful property: the speed of a sailboat fluctuates a lot, and instantaneous speed such as reported by a chip log isn't going to give you good navigational data.  The time integral of your speed, i.e., the distance traveled, is more useful. Paul Koning (talk) 20:13, 11 May 2015 (UTC)
