Welcome Redmax from Philadelphia PA. I hope you connect with all the great resources on this site. Do you live in England? British naval history is a big topic for many here on SoS. Would love to see a build log of your Occre Polaris, she's beautiful ship.
Looks like Occre is going the way of Artesania Latina for its entry-priced models. They are offering instructions through YouTube videos, and will most likely include few or no design drawings. When I built the Esmeralda level 1 build from Artesania Latina this year she did not come with any drawings, no rigging plan at all. Just the YouTube videos and a CD-ROM. I did an extensive SoS build log, so my troubles were well documented. I must say they probably saved alot on printing the design drawings, but the least Artesania Latina could have done would be to make the drawings available online. Good luck!
