I have textured the mast (was easy) and the ratlines (was a lot of work!). For this kind of small vessel, I made very simple lines - no ladder thingie - just to hold the mast, as would be in real life. But the good thing is that now I can build all the ratlines very easy, as I developed all the building blocks for them :-)
The one you see above is a detailed cut. If you want it a little more simple, you could go like this.

The ratlines have a front and back so they will look great from any side!
Once disassembled you can store it all quite flat and put it into a box.

Next ... the sails!
Happy building,
Chris
