You didn't mention where you were stationed. If you're on the ocean there's a good chance you're close to a local Hobie Fleet. JOIN!! The first time you show up for an event and identify yourself as a noob, you'll get swarmed with help.

You should get a jib. I'm pretty sure Rick carries them here. Mast rake is a question without the jib as the cable that you now have for a forestay may not be up to the job strength-wise. The jib does have a heavier cable in it.

Good luck and have a great time!
