huh ?   My quad  has a motor , and it floats ( upside down ) really well,  proven that several times over the years , Aparima river, soft gravel .  

I'll probably spend some time getting used to the different type of fish and what baits/lure work for them before I start adding the complexity of driving a boat and learning a completely different type of fishing. On top of that I currently drive a Golf and I feel like it would get tricky to transport the boat and find a suitable place to launch it.

Though to be fair I've never even considered kayak fishing but now that you mention it... I feel like this could be a lot of fun. Like I said, probably not in the near future but I'll definitely start looking into it. Is there a brand of kayaks you would recommend? I saw a pedal one on Torpedo7 at a decent price that looks really cool.

edit: You sent down a dangerous path my friend, I started checking a few "basic kayak fishing" videos and this looks like heaps of fun. It also alleviated some of the concerned I had about it. I'll seriously consider this option in a not so distant future.

And then the thing I leave behind to stop being ridiculous about overkill is usually the thing I end up needing.

Case in point: Few years back I took my son fishing in the far north on a father son special trip. We stayed on the banks of Parengarenga Harbor, the Harbor was dead.

On the last night we shot up to Spirits bay for a night time Kahawai session (by now my boy was desperate to catch anything).

We had about 15kg of Pilchards to use up (we took so much in a massive chiller that even heavy chunking of Parengarenga didn't use it all - like I say it was meant to be a special trip).

So before the light faded, as the tide came in, we buried a good 10kg of pillie chunks in the sand at low tide.

What do you know, as the berley ended up being uncovered by the waves in a little depth the Kahawai came in a school, and the Trevs as well, we landed a very nice haul of Trevally including three big Trevs (ok so I left two things back at base camp, my scales would have been handy to weigh the approaching 10lb Trevors before setting them on their way).

Then my son hooked and under water car that cut his line like a Wilkinson sword Razor.

Same thing happened on the next cast, and the next, so can you guess what item I removed from my tackle bag? ........heavy trace.....my 200lb black Magic trace would have at least bought us entry level passes to JAWS  in that situation and given me boy a chance of landing his first reasonable sized Shark - but who takes Shark traces Surf casting? Shark fishermen (I would not claim to be one of those even though I have used TLD's and a Kayak - whole Bonito to try get a Bronzie - I have never landed and released a decent one).

You cannot take everything. 

I concur with using Trolleys. I trolley all my gear into spots then use it as a live bait tank. 

I use a bucket styled trolley from Bunnings (cannot remember the brand it has worn off, those Gorilla ones look better than mine) but I need the bucket to hold water for my live baits slide baiting - they work really well if you change the water. Off the Warf I use a big white bucket with holes in the side of the top half (it is too heavy full of sea water - I use a 20 liter pale because they are sturdy, so with the holes it makes it a 10 liter/ 10kg lift from a Warf.

Obviously at the beach a bucket trolley is easy enough to fill with sea water for Slide baiting / any form of live baiting, without much fuss. 

A bunnings Trolley full of live baits with a covering to stop them leaping out (yellow tail are fine they settle quickly in an open trolley) some others like Kahawai you want to quickly use on a hook, or drape some netting over the trolley. The advantage of trolleys for live baits is although shallow, they have a large surface area for O2 exchange and so long as you add water here and there the baits stay happy enough.

I have not needed to use a aerator with a trolley system.  

Personally, bait fishing on a kayak is just too messy for me full stop. Plus soft baiting and kayaks are a match made in heaven. 

Burley from a kayak, especially in summer is asking for trouble. There are ways around it, i.e. burley hanging from a buoy tethered to the kayak with a loose knot in the rope. Not for me though.
