So where is the line for over-rigging your kayak?

My go-to gear:
landing gear: clip, bonker, grippers, gaff, all in a mesh bag that is also my net.
fishing gear: 2 rods w/ reels, pliers, knife, 1 plano tray of baits & tackle
paddling gear: VHF, fishfinder, GPS, compass, water bottle

wow, that doesn't seem like much now!

You want to see too much gear....
Just about any episode...

For rockfish you don't need much but if you are hunting salmon or c bass you need more stuff.  I flipped on a c bass mission with 5 leashed rods and didn't have any problems getting back in. Take the minimum you need to hook and land your target species.  VHF, compass, net, GPS, rod, reel and game clip would be my saltwater minimum.

I dont even have a kayak, yet. With that said I'm 100% sure I will go KISS with it.

im in the same "boat" so o speak, no kayak yet but i already have a miard of ideas of things to do to it... but even with all of my ideas i dont see that even coming close to being over burdened or over doing it. im a pretty cut n dry kind of person so yeah i say that now.... but we will see. with that said who wants to help me get into my kayak and buy my ar-15 off of me  so i can buy the yak i have my eye on?!

Two rods are a must.
I loaned my extra rod to Moose when he broke his at OC and to CHUB at Shelter Cove when he broke his.
I don't feel like coming back to the vehicle or having to call off a trip because my rod or reel failed OTW.
Floats, not leashes for me.
Less is definitely more.
After lifting CHUBs kayak this weekend I need to take a lesson from him. It was feather light.

I'm a hoarder - constantly trying to minimize...failing!

I am a gear junkie, to much bass fishing on a power boat!  I try to keep it simple now and follow the less is more crowd.  I try to keep most gear below deck and out of the way.  I got rid of the crate/tackle box in the back and now keep one or two small plano boxes and my bilge pump clipped in the center 8" hatch.  A few extra lures and flies are stuck in a pool noodle on my rod holder.

I have two rods which I leash in the back rod holders when moving or not using one of them, I also have floats on my rods.  Leashes are a pain.  I will occasionally use a third rod when making live bait with a sabiki.  I agree with Tote, two is my minimum due to failure, loss or backlash.

I have my fish finder, two rod holders, one in the tank well for my net, and another up front.  I try to keep one side open and clean for re-entry.  I have my seat and an anchor trolly.  Depending on wind I will have a small drift sock and/or kelp anchor.  I am finding I really do not need either with the hobie though.

My flag/light, net, gaff, knocker and game clip.  Usually a little dry bag with some snacks and water bottles in the center hatch.  I marked measurements on the sides of my kayak with a paint pen, so only use the hog trough on tourneys now.  One less piece of gear.  I also have a waterproof camera with a float tied to it.

The rest is on my person.  On my PFD I have a VHF radio, C-strobe, whistle, compass, dive knife and pliers.

I still feel like this is a lot and am trying to reduce further, but do not know what else to leave!  I only have two leashes on my kayak but rarely use them and may get rid of them all together.  Spray foam works great to fill open handles to make tools float.  It worked great on my net and a few empty handle rods.
