A tree grows from trunk to branch, from branch to twig. In the same way, every detail of whaling builds into the bigger story—and one small, crucial piece deserves its own full explanation.
I’m talking about the harpoon crotch, that little wooden fixture I mentioned earlier.
“Most green hands don’t even notice it till it saves their life—or almost gets them killed,” an old harpooneer once told me.
It’s a specially notched stick, roughly two feet long. We fix it straight upright into the right-side gunwale, right up near the boat’s bow.
Its only job? Hold the harpoon steady and ready.
The wooden butt of the harpoon sits snug in the notch, while the sharp, barbed metal head angles out over the front of the boat. That way, the weapon is always within instant reach.
A harpooneer can snatch it up in the blink of an eye, just like a frontiersman grabbing his rifle off the wall.
Standard practice is to keep two harpoons tucked in this crotch. We call them the first iron and the second iron.
Both harpoons have their own separate cords, and both cords tie back to the main whale line.
The logic is simple.
We aim to hurl both one right after the other, sinking both barbs into the same whale. If the first one tears loose mid-chase, the second one still holds fast. It doubles our odds of securing the beast.
But whaling plans never go perfectly.
The second the first iron pierces its flesh, a panicked whale bolts in a violent, convulsive surge. No matter how fast a harpooneer’s reflexes are, they almost never get a chance to throw the second iron in time.
And that creates a deadly problem.
The second iron is already tied to the running whale line. The line is screaming out over the tub, tight and fast. We cannot leave that heavy, sharp harpoon sitting loose in the boat.
If we do, it will whip around and slaughter the entire crew in an instant.
So we have only one choice.
We have to toss the second iron overboard, fast.
The extra slack box line coiled at the bow makes this quick toss possible, most of the time. It lets us dump the weapon safely without tangling the running line.
I’ve seen too many men learn the hard way—this quick fix doesn’t always save you.
Tossing the second iron overboard is one of the most dangerous moves in the entire hunt, and it’s caused countless terrible, fatal accidents.
Once that second iron hits the water, it turns into a roaming terror.
Sharp, heavy, and still tethered to the line, it dangles and darts wildly between the boat and the wounded whale. It whips through the water, tangling lines, slicing through rope, and lashing out in every direction.
It’s impossible to reel back in or secure mid-chase. We can only wait, letting that floating blade drift and thrash until the whale is finally dead and motionless in the water.
Now picture the worst-case scenario.
Four boats swarming one single whale—a huge, powerful, clever beast that knows exactly how to fight hunters off.
Between the whale’s strength, its speed, and the endless small accidents that happen in chaotic chases, you can end up with eight or ten loose second irons all dangling around it at once.
Every boat carries backup harpoons, ready to tie to the line if the first throw fails or pulls free.
All these tiny, intricate rules and risks matter.
They explain every chaotic, deadly moment of the whale hunts I’ll describe later. To understand the terror and frenzy of those battles, you first have to understand the hidden danger of the simple second harpoon.
