M25 measurements
Parker, If you want to e-mail me at jjbar96@hotmail.com I will take photos and measurements of the kit on my 25. I got the kit, and a hinged mast step from MacGregor. I have read posts about needing to put blocks under the deck fittings to bring them up some, etc. My fittings are bolted to the deck, the baby stays to the mast. I leave the stays on although it wouldn't take much to put a shackle at the top to make them easy to remove. I leave a little slack in the stays but only because the mast crutch is slightly to starboard of center so I need to allow the mast some movement when it comes down. The kt I have uses a block and tackle and not a winch but works fine and takes little space to store. The key, I believe, to the baby stays is to mount them in line with the pivot point of the mast. In my case this is the hinge point of the mast step. Mine works great.
