Search for Sunken Treasure

"If we weren't all crazy, we'd just go insane." ~ Jimmy Buffett
Yes, it may appear a bit crazy to drive back to Sesimbra for another bungled search for my Rocna anchor and chain - my third try. But wouldn't it be insane to stay home and miss out on the fun.

My brother Cesar filling the dinghy. We're fully equipped, including the "rock anchor" in the foreground a small grapnel anchor, a rusty chain to keep the anchor horizontal, etc.
Cesar's partner, Kathleen, went hiking up to the castle while we got ready. You can't beat it - on November 1 it's 23ยบ C, sunny and the calm bay faces a beautiful hillside town crowned by a castle.

"So where about did you lose it?" Cesar asks as we motored out of the port and into the bay.

"It's hard to say, exactly. I was so busy setting up the backup anchor that I sort of...didn't really...pay attention. But it's somewhere between up ahead and half way to the yellow buoy."

"Oh, OK. Hey, we got all day."

We tied the folded grapnel anchor a couple of feet ahead of the hook and then started motoring slowly, letting out line.

I'll be concise. It was hopeless, and we knew it right away. First the traction forced the dinghy to go in circles, and we couldn't even tell if we were actually moving anywhere.

Then we learned to steer by moving the line to starboard or port, that was cool. But it was hard to tell whether the force was just dragging force or if it had caught something.

"Feel something?"
"Yeah, I think so. Stop, let's pull it up."
"Nah, it's nothing, but it felt like it." Over and over.

Then we removed the grapnel and replaced it with about 5 feet of rusty 10 mm chain.

Same results, more or less, and the same tactic: feel something?, pull, nothing, damn, we're hardly moving, I think we're stopped, pull it up, nothing......

After hooking a coat, we removed the chain and used only the hook. That eliminated the friction and gave us a better feel of what was happening down there, like a spider waiting for the web to vibrate. But I suspect it was just bouncing around the bottom and not digging into the sand.

Time for lunch. We decided we needed a powerful magnet, perhaps a metal detector, maybe an underwater camera, a portable fish finder...Damn, I should have taken that diving course so that I could scrub Jakatar's bottom, but which I didn't and that would really be handy now.

I found some good magnets on Ebay. I think I'll order one.

Me and my brother Cesar. If you're wondering, he's fairly tall, I'm extra tall. He also owns a Corbin called Lapu Lapu, so he's like a duck in water, a marina rat and all that stuff. Kathleen's photo.
