I'll let others suggest outfitting. What I will suggest is, if you are a first time yaker:
1.Take your new ride to a body of water you're comfortable with.
2.Practice entering, bailing & re-entering your yak until you feel confident you could do it on open water. If you are already good with this, skip to step 4.
3.Take your new ride down to the surf with nothing but your Yak, Mirage Drive, Paddle & a PFD.
4. Practice launcing & landing in the surf until you physically cannot do it any longer.
5.Respect the ocean and you'll be allllright
Good luck!
