I am trying to decide the best place to mount a removable chartplotter (Navman 5500i) on a Beneteau Oceanis 311. The binnacle is pretty full with the standard navigation and engine instruments. One idea is to fix the mounting bracket on top of the perspex binnacle lid - making sure the lid can still be lifted for access to other instruments. It would partially obscure the engine instruments, but could live with that. Any thoughts?
