Any kayak anglers out there?

You don't say whether your yak is a sit-in or sit on top.  Mine's a sit on top, very handy style for fishing.

On managing tackle, some folks like a soft bag (like an insulated lunch bag) they put under bungies behind the seat.  Others like something larger like a milk crate they can zip-tie rod holders on to.  I've got built-in rod holders so just keep a handful of lures in a small case.  Don't need the milk crate. You have to adjust, of course, if you're using live bait.  There are purpose-built buckets for live shrimp, minnows but that's more of a challenge in a yak, esp if it's a sit-in rather than a sit on top.  

On paddles, I use a paddle leash.  Also have a paddle clip on the side of the boat.  I'd personally rather have a paddle that's too long rather than too short.  Mine's either 87" or 89", can't remember which. Best thing to remember on paddles is: light is good.  Paying extra for a lightweight paddle is money well spent IMHO.
