I'm always amazed at the ingenuity and creativity of builders on this forum. Glad you got the old bow eye out.

I'm sorry to say I have the same hardware on my boat(it looked cool at the time). I'll have to keep an eye on it, but I don't tow it very much and don't use it to tie up. Maybe I can rig a safety strap from the winch to my deck cleats? Any comments on that?

Thanks for bringing this potential issue to the forum.

My thoughts? Here ya go...

This picture is all over the internet...I'm sure you've all seen it before.

Point is: you can't predict what will happen on the highway, and if you're in an accident, NOTHING is more important than keeping the boat on the trailer. So what went wrong here?

Image

The kinetic energy of a boat of even marginal weight during a wreck is tremendous. "A body in motion..." and all that other cool Newtonian stuff. Keeping the boat on the trailer requires straps and chains:

Image

And a die-cast pot metal bow eye simply isn't going to survive. Just from basic towing, mine is already developing stress cracks...I can't imaging it surviving a wreck. It's quite literally the "weak link in the chain". This is the biggest reason I'm changing mine. Plus all the other reasons I cited...

Do the cracks in the bow eye radiate out from the threaded hole? Could they be seen before removal?

Did the whacking cause more damage to the bow eye, as well as the shackles?

Did it make the cracks worse?

Yes and yes

I didn't take that close of a look at it, but it didn't break apart. The cracks *might* be superficial...there's no way for me to inspect them at any meaningful metallurgical way. The shackles looked fine, but I couldn't get the threaded barrel to move on one of them, so deformation and/or galling occurred. I pitched both of them along with the eye.

Definitely some useful and interesting information here. I too started off with that same bow eye, mainly because it was the only one with a long enough threaded rod. But after drilling the hole early on, I had second thoughts about the strength for pulling a heavier boat. Admittedly, I was concerned more about the shear strength of the single threaded rod, but the concern was the same. I do wish someone would make the "U" style with longer threads.

After I had put in the single eye, I found a place that would make them as long as you want them at not a bad price. I'll try to fined them again.

Just a little on the outside will seal it. no need in the holes, it’s not even under water.

You missed the 4th thing that can happen by "misusing" a tool: you get the job done. My dad taught me to respect tools, never misusing or modifying them.
I now disagree.
The best mechanics I have ever known were all about getting the job done; if it meant you had to grind a wrench to fit in a tight space, so what ? Think about the old fashioned one piece flat screwdriver. It is far better than the newer drivers that take bits for some jobs, because it is also a small scraper and pry bar. I imagine that prying and scraping may be as frequently done as turning a screw.
Don't get me wrong: I am not advocating unsafe misuse or abuse of your tools. I am saying that the task may be more important than the tool. If there is a purpose built tool available, use it ! All too often, there is not, and adaptation and improvisation may be required to overcome.

By the way, good work reinventing to slide hammer ! And I admire your persistence in finding the right solution. When I built Mr. Jon and Pirogue, I installed the bow eye (sold by GlenL) with epoxy, having no intention of replacing it. I had faith in the bow eye and my work, so the installation was permanent. Also, I never intended the bow eye to be the sole fastening point; I always used a couple of ratchet straps across the hull and at the transom when it was trailered. I figured that the bow eye was for towing, and for winching onto the trailer, not a hold down.

Well, the guys in the weld shop did a good job. They ground away half the material on each piece and made lap joints, so there's a lot of overlap of material. They TIG'd it and got great penetration. I ground & flap-wheeled the finished product clean enough that the assembly would slide into my bow holes. They also TIG'd the front nuts in place so this assembly can't loosen up.

Image

When I took the old bow-eye out, I saw that the washers on the inside of the hull had displaced just a bit into my stem. Not a lot, but you could see the washer's imprint deeper than I liked. Edge-compressing plywood is never a great thing to do, so I decided to make a "displacement bracket" from some scrap angle iron I had laying around:

Image

And here's everything installed. Maybe the bracket isn't necessary, but I'll sleep better at night... :)

New bow eye installed!! With two new coats of bottom paint & hull paint, everything is looking pretty good!

Good information. I havent installed a boweye on mine yet. I'll do that this winter along with a cutwater. I was thinking of doing what you did and think I will do that now.
