To be able to keep track if your trim settings of your IOM we have made a trim logbook were you can note down your settings from time to time. It is in English but we are working on translations.

How to print and make the book:

1. Download the pdf by click >>here<< or on the picture above
2. Print only page 1, the cover
3. Print page 2 as many A4 sheets as you like, then turn them over
4. Print the backside as well, check for the right direction.
5. Stack them and fold in the middle and fold the cover page around and staple it in the middle and you have a nice trim logbook
6. If you want a “deluxe” version you can fold a transparent plastic sheet around as well. A nice finish is to sew the middle with a normal sewing machine instead of staples.

Good luck and have fun!
