Hey guys, new to the forum, first post and looking for some help.

I just bought a 1998 Nacra 20, love the boat. The boat came with a spinnaker pole/spinnaker and I believe it was bag launched by one of the previous owners but not the guy I bought it from. The guy I bought it. From said he never took it out of the bag and didn't know anything regarding the rigging. It did come with some extra blocks but I need advice on rigging. Oh and I'm gonna be using a SNU. Any advice, pictures or diagrams would help a lot!!!

On another note I could also use some help with the mast rotation and how that's rigged as well.
Thanks in advance!!!
