Wow, some horror stories here, I don't feel so bad about mine now....
I lost the very first "high end" rod I ever bought myself when I was 15... was a mean bad ass, Team Daiwa Larry Nixon rod, that I bought with many saved poctet money's and saved up cash from life guarding.... Used it for everything from bassing to fishing plastics offshore, best fish being a Grouper/Cod/Trout of about 8 kilos and a mulitude of little Trevally's and others....
Surf launching on our Zodiac with a buddy after school one day, we had the rods lying flat on the deck as the surf was around 4ft, and we had about 300 metres of white water to punch.... somehow the bl00dy rod managed to slide backwards on the deck and slip itself out through the scuppers in the transom...... only noticed when we were rigging up 20 minutes later.... bugger!
My first Wahoo when I was living in the Caribbean, similar story... Had a beuat little custom stick I used for everything from throwing plugs to swimming livebaits for Tarpon, and doubled as a nice little lifght trolling outfit... Couple of us on board a friends Mako CC, more of a booze cruise than a fishing mission, I got hit on a broken back minnow....
We'd caught a bunch of small Barracuda, which are a pest in Cayman, and figured it was another but the fish took off at pace, and turned out to be a little 'Hoo in the 10 kilo range.... As she got boatside, we realised no gaff on board, so my mate leaned over and tailed her, and as they do, she went ballistic and threw the minnow immediately.... being my first 'Hoo I didn't want my mate to drop her, so put the rig down behind me and dived to help get the 'Hoo on board.... little did I know that in my haste, I didn't realise that "behind me" was actually overboard..... over a 1000ft deep drop off..... once again once noticed when it was time to set lines again....
I've chucked a very favourite ring into the ocean too.... present from my Mom, an awesome old chunk of silver.... was just a little big for my ring finger, but I didn't want to wear it on the middle finger, so insisted on keeping it on the ring finger.... Gutting Spaniards on the beach in Mozambique, I chucked a handfull of gills and guts into the surf and along with it, my ring went flying into the surf.... forever gone...
Geez, I never realised how many of these stories I've got.....
