The object wasn’t a patch.
It was a cylinder.
He drifted back a foot to get a wider view.
Attached to the hull, tucked neatly into the hydrodnamic shadow of the rudder, where the water flow would be least turbulent, was a 6 foot long metal tube.
It looked like a torpedo, or perhaps an old depth charge bolted directly to the ship’s skin.
“What in the hell?” Jake thought, the words echoing in his skull.
He moved closer, inspecting the attachment points.
These weren’t welded.
They were massive C-shaped industrial clamps, the kind that required pneumatic tools to tighten.
They were hooked onto the flange of the rudder housing biting deep into the steel.
The cylinder itself was streamlined with a conicle nose and a flat rear, clearly designed to endure the friction of a trans oceanic crossing.
Jake’s blood ran cold.
In the post 911 world, commercial divers were trained to look for anomalies, but usually that meant checking for drugs in the sea chests or hearing about smugglers welding boxes to the keel.
This was different.
This looked like a weapon, a mine.
The thought seized him.
If this was in limpet mine, intended to blow a hole in the rudder and disable the ship in the channel, his scraping might have already disturbed a trembler switch.
He looked at the clamps again.
They were heavy, corroded, but solid.
The device was painted orange, which was odd for a weapon.
Mines were usually gray or black to blend in.
Orange meant it was meant to be found or meant to be retrieved.
He checked his air.
He had plenty, but his breathing had accelerated.
He needed to surface.
He needed to clear the area.
But first, he needed to be sure of what he was seeing.
