Halibut Harpoon

After hearing about the humongous pac hali at GS6 that was too big for the gaff to handle I decided to be prepared should I ever hook into one.
I got the basic idea from this guy:

The difference in design can be seen right here.



I took a hard wood dowel and made a dado grove down the center.
I drilled 2 holes right next to each other. One to secure the tip and the other to secure the loop at the end of the handle. I used 3/8 aluminum rod, 3 ft. each, but cut off the excess after I fashioned both the tip and loop.
I made a 90 degree bend at the end of each rod. The end of each bend fits into the drilled holes while the rods rest in the channel with just a little bit sticking over the top.
I then wrapped the dowel with rope and smeared Great Stuff all over the handle. Make sure to use either rubber or latex gloves. Spray the Great Stuff in your hand and rub it over the handle. Scrape off as much excess as you can.
Not only does this glue the rope together it will make your harpoon float like a cork.

Here's the supplies needed to make the slip tip:
9/16 Brass tube, 1/8 ferrules and stops, 3 ft. of 1/16 plastic coated cable.



I heated up the brass tube and smashed one end in a vice. Then I put the smashed end back in the vice and bent the corners to fashion the spear tip. Sharpened the edges with a grinder.
Cut the spear tip to about 5 1/2 inches long.
Drilled a hole and ran the plastic coated cable through the hole and crimped the stops in a vice. Made sure the loop for the spear tip will allow the tip to rotate completely through the loop.
Since it is a slip tip I use a rubber band to hold it in place which the video will explain.
There should also be another line clipped to the free loop. It should be approx. 15 feet long with a section of shock cord and is clipped to your kayak.
Spear the halibut all the way through. The harpoon pulls free but the slip tip remains through the halibut which is secured to the line attached to your kayak. Let the monster wear itself out and then haul it in for dispatch.
Total cost was less than $30.

Nice! Hope the opportunity to use that weapon 'surfaces'. 

Thats a nifty idea. I may have to rig one up....

All you need is a shortened pole spear with a slip tip on it. They've been using them on boats in Ak for a long time. That and a bang stick.

Hey Mike when I went out with Sean I brought my shorty pneumatic speargun. I rigged the spearshaft break-away style to a couple crabpot floats so I could let go of it just in case........ Just say'n

It won't float and isn't as cool.  You also need to put some umph behind it since it isn't being fired. I like the thicker grip.

Now there's an accident waiting to happen.

The possible loss of the gun would be way more expensive than this. Plus you just gave up your sleigh ride.

The spear was hooked to the buoys not the gun and the buoys had a line to my quick release cleat.

Pac halibut expedition time.
nice work there Tote!

Pac halibut expedition time.

Hell yea.
Road trip anyone?????

I would build one but I need to learn how to catch them first 0-5

This is Bad Ass!!!    Mike, I like your style    I've been thinking of buying a pole spear for the same reason, but this is much better 

Mike that's badass! Can use it on t-sharks too.

I'd test it out on a perch 

Very cool, might want to make a quick release in case the landlord takes intrest like that blue shark video! 

I just had an image of this harpooned bleeding fish dragging your boat and the image of the blue shark and the GWS came to mind.  Now your hooked to a GWS, hmm could make for a very interesting sleigh ride..."We need a bigger boat!"
