I just noticed that my Sun Cat's sail throat is attached to the gaff with a pin. See the attached pictures. I think it's called a tack pin, and it's probably this one: https://dwyermast.com/tack-pin-small/. It caught my attention because the sail corner was almost detached from it. Looking at it closer, I don't understand how this is even remotely a good idea to use a pin that can rotate and pull out by itself. How do I make this more secure? Replacing the small pin that prevents the tack pin from pulling out with a cotter pin seems like a bad idea as the cotter pin might rip the sail.
Yeah, not the most secure fitting, but it can be moused with monel wire as you would other critical fittings. They're useful for situations where the sail is removed frequently. I doubt that's the case for any Sun Cat.
You could also replace the roll pin with a ring ding, as Dwyer used on the gooseneck swivel also seen in your photos. That would reduce any concern you have that the sail could catch on it.

That is a great suggestion, thanks! For anyone else looking at this, these rings are also known as cotter rings.
