Stanchion problems

I am having an issue with the hole for the lower life line on both the port and starboard side stanchions. The hole has crimped both life lines after the winter. These stanchion holes were punched out last year as there was some compression on the stanchion caused by the travel lift out rigger the previous year. I am wondering what would cause the holes to close up or shrink. I have a 1994 Legend 37.5.

Tight cover slightly bent stanchion at weak point (hole)? Cover tiedown lines shrunk after being wet.

There is a plastic plug in the stanchion at the lower lifeline hole. The stanchion can fill with water, and when it freezes it will push the plug up, crimping or even breaking the lifeline. This happened on my old Hunter 30G, which has identical stanchions to my 37.5. You may be able to confirm this happened by unscrewing the vertical bolt under the toe rail holding the stanchion, and water should pour out. You can also confirm that the plastic plug was pushed up, and that the lines aren't bound some other way.

After getting new lines and drilling out the plug, I drilled a small drain hole just above the base on each stanchion.

hi Bob, do you know where I could get a replacement stanchion for a 1986 hunter 40?

Try at the SBO store here. They were quick to deliver and at a fair price. Its my go to source for Hunter parts.

Three of mine froze. The plastic slug pushes the line up until it shears off. I found one line just dangling the water after several freeze and thaw cycles. SBO is your buddy! Thanks guys!

PS... Stainless hex socket head bolts were the ticket to a very secure base to the toe rail . No fiddling with Phillips under there.....

That is an interesting image of the stanchion and the plastic covered lifeline wire.

The stanchion holding water then freezing and expanding is an interesting operation on the wire. Do stanchions have clean weep holes at there bases? Should they?

I can imagine how the freeze thaw action can damage the plastic covered wire, open the wire up for water rust weakening and eventually breaking the wire.

JSSailem that is exactly what happened.
They did NOT have weep holes nor did the new stanchions from SBO.
I did drill weep holes before mounting the new ones back on the boat.

I had this very issue on my 96' 37.5. Here is how I resolved it. I actually got to new stanchions from the Hunter Store on the website. At $89 a pop I decided to see if I could do some sort of repair to the rest of the stanchions that didn't cost so much as I had at least two more in the same situation. After studying stanchions on my friends Catalina 380, I noticed the stanchions on his boat had a metal pass through tube for the lifeline. What I did was went on Amazon and found stainless metal tubing that would pass the lifeline through, then cut to a short length that would pass through the stanchion and extend about an 1/8" on either side of stanchion line hole. I had to drill out the original hole where the line went through the stanchion to fit the stainless steel tubing piece. I pressed the stainless steel tubing piece through the stanchion and viola, no more issue with the lifeline getting pushed up and cut. I also drilled drain holes in the bottom of my stanchions. I did pull the stanchions from the boat to do these repairs in my garage at home where I have the tools required. I also noted when pulling the stanchions that there was some pretty significant galvanic action going on between the stainless stanchions and aluminum tow rail. after cleaning up the corrosion I made plastic washers out of a milk jug to act as an insulator between the stanchion and tow rail. I also used anti-seize on the tow rail mounting screw when reinstalling the stanchion. If I remember I will take some pictures and put them in another post to this forum. I now have two spare stanchions in my garage.

Here are the photos of my stanchion repairs. If you look close you can see the drain hole i drilled in the bottom and the milk jug spacer I used between the bottom of the stanchion and toe rail. hope the pictures help.

Nice job. Now you just need a tool to once a year stab into the weep hole to keep it open. What about the space between the weep hole and the rail.
See you used butyl under the braces. Did you prep the deck holes with a bit of campher to help block water intrusion down the screw holes? I am guessing butyl beneath the stanchion to stop water from getting into the boat underneath the stanchion.

But couldn't you now bend that stanchion with your hands? The tube is buckled and there isn't much left. Or was much of the distortion from prior freeze damage?

Safety Concern: If... you are removing the stanchions and strengthening or replacing them.... This is the Time to upgrade the whole attachment system, especially the gate stanchions which are are woefully under-strength on most stock boats.
We tackled this when I removed all of ours to reinforce the underside of our deck a number of years ago.
Being able to actually use the gate stanchion to help yourself on and off of the boat is one of the best upgrades you can perform. And, ALL of the crew and family will love the upgrade.

Actually, the stanchions are very rigid with no flex. I am grateful this is the case. They seem to be as strong as before. However, I did not give them a pull test like we used to do in my Navy days with a test device designed to do a calibrated weight test. My gate stanchions were just fine so did not mess with those. I was pleasantly surprised to find the screws on the two smaller legs did not just pull out of what I figured would be a soggy core. I have been gratefully surprised that every time I have done some sort of repair that involved the deck that I found the core to be dry and solid. I have installed an Anchor windlass (which my install is on the website under Hunter 37.5 projects), did the stanchions, and a few window leaks. I do take measures to ensure my repairs are as waterproof as I can be with epoxy resin before I reinsert the fasteners. I did not use camphor. However, I am a strong proponent of 3M 4200 in such an application. I use a straightened paper clip to clear the weep holes whenever I think about it. I spent 30 years in the Navy on submarines responsible for a myriad of equipment and preservation thereof. Here is what I learned from all those years in the Navy. If the Navy uses it, it works. If it is environmentally friendly it doesn't work. Now please don't respond with all the tree hugger stuff, I take every measure I can to keep our waterways and environment as clean as possible. Just sharing my experience from serving in vessels that spend most their life in a very inhospitable environment as well as being one who had to maintain many of the equipment and machinery that enabled those vessels do operate in that environment. I love this website and all the information sharing in it. Keep it going my fellow sailors.
