As a veteran "cruise ship" guy. I have seen various anchoring systems. One is a simple turnbuckle system where one side attaches to the underside of the piano (grand) and the other to the deck. The castors have been removed and replaced by a flat pedestal. Tighten the turnbuckle to "fix" in place. The other involves removing the castors and inserting the pedestal into the leg cavity, which then is bolted to the deck. As to the stresses on the leg plates, this has yet to be a problem caused by routine ship movement. Unless of course it has become dislodged from the bracing. Then it becomes a 750 lb missle. That I've seen. But then it is more a matter of replacing the legs and plates. Yamaha pianos have the bolt system, the best in my opinion. Especially when it comes to moving and replacing the legs. I've seen many leg systems damaged by movers not replacing them in the proper order. Yama's are an idiot proof system.

I think that the posts on this thread described the legs being braced in some way. Or maybe the undersides of the pianos were tethered to attachment points on the floor - no leg bracing necessary. > I remember that the Loma Prieta earthquake near San Francisco > broke some leg plates. Many grand piano owners think that they should dive under their stout-legged Steinway in the event of a temblor. Loma Prieta proved otherwise. I'm still replacing leg plates from that quake.
