I have a Hunter 23 (1984) and recently met with a stump or something that kicked up the rudder (as it should) but shredded the line that holds the rudder down. Someone asked me if it sheared the pin. I don't have one that I know of and wondered if someone can tell me if this years model had a shear pin and if so where I should look as I don't see anything. If not, can one be added? Where should it go and what procedure do you use for creating one?
