Navigation Question

[jlandells]

Since tidal curves are an important tool for accurately predicting tide heights, why is it so difficult to find them outside of nautical almanacs? Surely, a single curve in an almanac won't last long if you're constantly using it and erasing marks, but the thickness of the almanac makes copying difficult!

Am I missing something?

If you use a 4b pencil and don't press too hard it helps preserve the page.

A Scanner?

Scan the page, print it out, laminate it and Bob's yer uncle. Tickety boo.

Exactly what I do for teaching! Print them out to A4 size.


Oh, use last year's almanac and take outh pages you want. Or if you have the loose leaf version even easier.

I do the same with computation of rates tables

It gets a tad expensive with the Sight Reduction Tables though if you want to compute your sextant readings!

I use an app too and my plotter's tide curves as a back up
