Yes that will work. But with Windows images and on the high seas you never know what is going to happen. It would be much safer if you made your images with free Macrium. That is a reliable, easy to use imaging program.
I have made a tutorial that will help you to use it.
For the recovery CD,
download the latest iso from my OneDrive and burn that to CD. This is the latest version and downloading it from my OneDrive will save you a couple of hours downloading the WAIK that you would need to produce it yourself.
And don't just make 1 single image but make new images frequently (e.g. once a week) so that you are always up-to-date in case you have to employ it. An image that is a year old is pretty useless.
