Gentlemen

Attached is a form that I cobbled together quite a few years ago and tweaked a 
few times before I got it to where I wanted it to be. Cannot say there is no 
duplication/transfer of numbers but I do not see this as a problem.

Bit of explanation: Form is designed to be printed double-sided so you can 
reduce four sights on a single sheet of paper. Note under sextant 
corrections, "total correction" is placed above refraction, additional and 
temp corrections. You add the total corrections, scribble them on the blank 
white space below and then transpose it to the "total corrections" box. Why? 
Just to make it easier to subtract the total corrections from the App. Alt.

Other notes: although I devised the form primarily for electronic calculatior 
reduction, it can also be readily used with HO 249, hence the reference to HO 
249 in brackets.

Finally, I squeezed in some basic formulas and rules so they are always in your face.

Of course this form works fine for me but I find that with experienced 
navigators, the type of sight reduction form one uses tends to be a personal 
thing.

I got thick skin (I'm married) so feel free to critique.
