The mast step hinge plate on my O'Day 25 is troublesome for several reasons. Friends with other boat models (Catalina 25 for example) have mast hinge systems that involve two vertical stainless plates ("ears") on either side of the mast with a single stainless bolt going through them and through the bottom of the mast. Seems real simple, strong, and versatile. Have seen other systems like this which have holes through the stainless "ears" for mounting halyard blocks and other rigging. Anybody replaced their original O'Day 25 mast steps with such a system? Specific brand recommendation? Installation issues?Dick StraubelEphraim, WI
