Don't worry about that, just print that one out, build it and when it's finished you'll find another
Print the model twice - this way you'll have extra parts if you make mistakes.
The best way to start with making models is to make small stuff first. Don't start from the hull, instead make small repeating details, like the drums on page 9, the boxy superstructures and other objects on the board.
Start with the parts that are repeatable (there many of them). Make each one as if it was a new model for you. Don't worry if you make mistake - if the part looks not good then simply think over what to do better , cut out next one and glue it again. For example there is 15 parts nr 11 - if at each one you try to make it better - then when you'll make the 15'th it will be very nice looking. Then simply throw away the ones that look substandard, take the second printout and glue next until you have 15 nice parts nr 11 - if needed print the page 9 again.
Many people start from ships, make the hull, perhaps some superstructues - all that crooky and with gaps - and then get bored with the small stuff and drop the model and sometimes modeling in paper altogether.
If you resist this notion and build the ship the other way around, starting with by gluing the repeatable stuff, then you'll learn to assemble the parts precisely. I mean - if there's 15 pieces then you have to make at least one that's good looking. Use it as a standard and try to make all 15 as good or better. Treat it as a model in itself. When you make it then you're ready to tackle next parts on page 9 - the same way. You'll find that now you will make less mistakes and glue it both better and faster.
Choose parts that are like a models by itself - like drums, boxes, rescue boats, chimneys, superstructures, starting from those that are small and most numerous and
ending on the largest and singular. When you get to the superstructures you may be able to make them good looking at the first try, without the need to repeat gluing them. Finally make the hull and glue onto it all the parts you've made. This will be real fun and exciting - the model will pop out as if by itself, all crisp, shiny and good looking. This can make you so fired up that you'll want to make another model like that.
Enjoy!
