Did I just let that happen? Costly mistakes on the water

Inspired by a report on lake Collins and a large trout that is still swimming instead of in a smoker, I started reflecting on my greatest moments of personal disbelief while in the saddle of a kayak...
1. Dropped car keys into a frozen lake almanor, no cell battery life to call for help... Sh*t!!
2. Dropped cell phone into same lake six months later approx. 100 feet from likely location of lost keys 
3. Lost downrigger ball seconds after making 10 mile paddle to fishing grounds... Return to car for spare ball? What's the point in having a spare if I leave it in the car?
4. First week of owning a kayak, found myself a long way from shore with a broken rudder VERY rough water and... No life vest!!?? almanor again
5. Tried to make a landing on a real muddy shoreline at SPD. Sank into knee deep mud struggled for 10 mins to get unstuck, back on kayak which has also become stuck in mud, try to push off with paddle which sticks in the mud so well it breaks  finally get free of the god forsaken shore to realize I still have to pee

What's your top five or just worst overall?

After watching many home vids from socal where guys landed in surf with their rods out in holders I tried it on the wrong day....that reel is still in pieces in a box.

Surgically removed two driver's side truck mirrors from my old bronco when the kayak I was loading slid off the roof. I was especially pissed the second time it happened.

I've been lucky!

Oooo yea, how could I leave that one out? Looking at some large dents on the hood of my Subaru now from when I forgot the tie downs... Did I really just do that?!

Pre Kayak
Let's see! there are two times that I remember well. The first time I was with my friend and we were on the delta fishing in a tournament. I'm on the back deck and just got through landing a good 3+ fish, lay down the rod, unhook the fish, and place him nicely into the livewell. I turn to pick up my rod and it mysteriously disappeared.
Second time me and the wife were on Collins lake fishing near the dam. Wind picks up so we decide to move and I did not strap down the rods. Well we hit some wakes and after a few bounces one of the rods bounces over the side of the boat. Turn on the lowrance and we are sitting in 70+ feet of water (Good bye rod number two).
Kayak
Only thing so far (knock on wood) was I lost my yellow measuring board at Rancho Seco last year. The thing went over board and I figured it would float. Well with the wind blowing I took my time in turning around to get it and by the time I got around it was slowly sinking out of view.

Nothing too horrible for me yet, but I've lost 2 pair of sunglasses, exactly the same way both times.    

I put my glasses on my hat/head, forget its there, take hat off to get some air and poof, there goes the sunglasses.  I really need to stop doing this, especially on the troll.

On my 2nd trip out, I pushed the kayak too far towards the front and it slid down my windshield.  The kayak had bunch of rocks/pebbles on the bottom so now my windshield looks like crap.   

Worst thing ... so far, is loosing my singlasses at the bottom of Coyote Res.  Lucky for me so far.....

   As far as boats is concerned, I've had blown tires & blown O/B motors ....  & that's just at Lake Don Pedro.

I lost my sunglasses out crabbing in Trinidad. I found them in the trap after an overnight soak.

No crab, sunglasses make poor bait.

i got one for you, a couple of years ago a friend wanted to borrow  my kayak to go camping with his family and i was lazy and instead of putting it on the rack and he lives about 1/2 mile from my house i put it inside my excursion when i suddenly hit the brakes it went forward and cracked my windshield.

about 15 years ago i was pulling the anchor on my friends ( Bret/ nosoupforu and his dad) boat and my cell phone went in the water. I keep on trying to forget about this one but Bret keeps on reminding me.

Years ago in Trinidad with Brandi - the last time I took a non-waterproof camera OTW with me.  I dropped it in the drink.  (I'd already done that in tidepools along shore with two others while fishing).

Since I always cruise with waterproof cameras now, the latest disaster was when I inadvertently hooked onto a caribener on my new Pentax last June and flipped it out of my PFD pocket and right into the drink.  I thought, "I should've had a float on that" as I watched it sink two miles off of Humboldt Bay.  I had a fish on at the time, and if you jack the video up you can hear me swear under my breath as it happened.   

Jamming back down to the ramp to setup scoring at GS7 I had my rods in the front holders on my X-Factor which was on the racks.  As I drove out of The Tides driveway I heard a snap...  Got lucky not to destroy the rod, but the rod holder got completely torn out of the kayak.  Easy surgery...

When my first X-Factor was still new in '07 I used to haul it in the back of my pickup.  I backed up over my straps and felt like I'd just ran over a stick, but I knew there was nothing there.  I got out and realized that running over the straps had buckled my boat and cracked it all around the center hatch.  Easy surgery with maintenance requirements...

Overall, I feel lucky to have not suffered through more losses.  (knocking on wood).   

Lost my favorite ocean rod/reel when the downrigger it was in broke off.  It was sad watching it sink.

Also left my custom net in Yellowstone after fly fishing.   I was too far away to go back when I remembered. 

I don't want any more lost gear, but I am sure it will happen again.

After spending a day on a panga in Los Barriles I went back to the rental and jumped in the pool .....with my wallet and iPhone in my pockets.  The iPhone was toast but nothing was ruined in the wallet. 
Oh, yeah.... I forgot to mention the margaritas between the fishing and the dive in the pool 

My Pentax Optio in the drink at Melones. It's probably out of the water by now.

These did not happen when I was on the water but they are kayak related:
When I bought my Hobie Pro Angler in the summer of 09 one of the guys at the shop where I got it helped me load the PA and said I should load the PA upside down on my 1940's 1/4 ton Bantam trailer.  I stopped on the drive home to fuel up and when I went through the driveway of the gas station the front of the PA dented my new Tacoma's tailgate and chipped and scratched the Snug Top bed cover.  The PA was too far forward so I loosened the straps and moved it back about 12".   
Had a couple of Scotty rod holders bounce out of the Bantam trailer on the drive out of Heenan Lake's dirt launch road, did not notice until the next trip when I could not find the rod holders (I leave all the kayak gear stored in the trailer). 

Donated 2 iphone 5s within 2months of each other, vhf radio, and theres still a big ling swimming around with a lip grip hanging out of its mouth.

Lost rods/reels because I got lazy/over confident that I didn't put my rod floats on THAT particular day. Harder when it happens twice. That's when I really learned my lesson and now religiously put floats on my rods.
