    Re: Interpolating a traverse table

    Thanks DaveP. Thanks also to Lars and DavidI and Frank for comments and suggestions. NavList is such a generous site for facilitating helpful and informative sharing a common interest. I made up a truly compact traverse table (TTT) to make life easier (and quicker at the chart table); particularly useful when the off watch leader doesn't like plotting or log keeping. It is 1 page, double sided, covered in adhesive plastic for durability. Course angles every 2.5. Distances every 0.25 miles. Scalable. I can use it for entry with course and distance to find dL and P. From mL and P I find dLong. Or the reverse, by eyeball scanning, I find approx course and distance for given dL and P. Given all the other forces affecting a yacht's track, plus measurement errors, it is approximately right. Better than being precisely wrong.

    If the site permits me to include a link to youtube, here is a link to a short film covering some of my sailing last year. Akala is my yacht. Sail number S27. Home club: Royal Melbourne Yacht Squadron.

    What is NavList?

    NavList is a community devoted to the preservation and practice of celestial navigation and other methods of traditional position-finding. We're a group of navigators, navigation enthusiasts and hobbyists, mathematicians and physicists, and historians interested in all aspects of navigation but primarily those techniques which are non-electronic.

    To post a message, if you are already signed up as a NavList member, start a new discussion or reply to any posted message and use your posting code (this is a simple low-security password assigned when you join). You may also join by posting. Your first on-topic messsage automatically makes you a member, and a posting code will be assigned and emailed to you for future posts.

    Uniquely, the NavList message boards also permit full interaction entirely by email. You can optionally receive individual posts or daily digests by email, and any member can post messages by email (bypassing the web site) by sending to our posting address which is "NavList@NavList.net". This functionality is similar to a traditional Internet mailing list: post by email, read by email, reply by email. Most members will prefer the web interface here for posting and replying to messages.

    NavList is more than an online community... more about that another day.
