After helping a friend clean up his Olson 25, we re launched her and steped the mast. a week later he gets a phone call from the dock master, your mast has come down. apparently the clean turnbuckle threads and waiting untill next weekend to install cotter pins were no match for a week of slow pulsing of the headstay at the dock, just like not using safety wire on your anchor shackle she just walked off. Being deck steped, down it came. luckly landing in the neighbors rigging to soften the blow. Boy do we feel stupid????
