Need some help. Boat is on the east coast, I am in the midwest. Need to know the diameter of my bobstay for the bow sprit. I will order here and install there a pvc tube to prevent chafe on mooring and anchor snub lines. The boat is a Tashiba 40, probably any of the Perry boats of this size would be the same. I am interested in the diameter of the end of the stay itself without the turn buckle. The approximate length of stay would also be helpful.

Thanks
