[edit] Merger with Log_(speed)

• Agree - These seem to be similar enough pieces of nautical equipment to warrant merger. --Adamrush 20:36, 18 February 2006 (UTC)
• Agree. They are the same. CharacterZero 00:27, 1 April 2006 (UTC)

[edit] Readability

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)

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)

[edit] Miscellaneous incorrect info or misunderstandings

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. Michael Daly 05:46, 1 September 2007 (UTC)

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)
