Clevis Pins

My wife and I just bought a daysailer which we sailed for the first time yesterday. Probably 90% of the set up time was me fussing with the split rings on the clevis pins. Is there a better way? Can I just replace the rings with R style cotter pins?

Related question- it looks like some clevis pins were replaced over the years with ones that are too long. If I replace these with ones the proper length, do I need to worry about some kind of strength rating or will any stainless pin suffice?

Thanks!

Re: Clevis Pins

Length is probably not important, whereas diameter of the pin is - but you know that. Personally, I'd continue to use the split rings since regular cotter pins and R style have the sharp edges that could rip the sails or the crew's skin. Too much of a pain to tape up the pins everytime you launch.

Re: Clevis Pins

I agree that split rings are the way to go; cotter pins can only be used so many times.

On my rings, one end is bent to poke inside the ring. You put the clevis pin opening over that and pull the ring; it opens right up.

West Marine, about $3 each (5/16"x3/4"); gear that works without problems: priceless.

Re: Clevis Pins

Maybe a quick release clevis pin.

Pit pins are great but bring $$ when you go to buy them. I don't know if they are made short enough for your needs though. The diameter of clevis pins is the only dimension that matters for strength. Length is an "as required" measure. Too long just snags things, it doesn't weaken anything.

A type of clevis pin is available that has a swiveling tab at the end that pivots out and makes a T shape of the pin - those might work well since they are more secure than the spring loaded pin type.

Re: Clevis Pins

Be careful of the quick release pins. The ball is very hard and can wear way the material in the chain plates or other attachment points. I learned this the hard way on my old Hobie. Use the fancy "ring dings" (split rings that Zen mentioned). I used to rig my Hobie in minutes with these. From trailer to ready to sail in the water in 15 minutes.

Re: Clevis Pins

Thanks for the input guys. Good advice. I guess I'll stick with the rings and try to find some better ones.

Below on the left is a pic of the rings I have. I believe the larger diameter ones are original and the smaller diameter is a replacement. They are heavier gauge wire and almost impossible to use, they have no give. I was using a screw driver and needle nose pliers to pry them open and slide them on. I guess I will just have to find better ones.

Below on the right is a picture of what I'd like- clevis pin with an attached retainer. I've seen these type at the hardware store but I doubt they make them small enough for this purpose.

Re: Clevis Pins

I haven't found a good replacement. Their are pins with push button releases used in avionics, but are more spendy than even the marine ones. The rings really are your best bet for a small trailerable boat.....unless you invent something better?

Re: Clevis Pins

If it was me, I’d stick with the split rings. You can save your fingernails by buying some split ring pliers from a place like McMaster-Carr. After-all, “quick release” and standing rigging really isn’t the best combination. That said, back in the o’ Hobie Cat days, we used quick release pins like the illustration. We also wrapped a little electrical tape around them. You could probably get by with Velcro.

I was looking for one of these for my anchor - I think they are called Quicklock pins :
