The prior owner of my vessel put in new flooring and I am trying to figure out how to correctly mount the salon bench in the center seat on the 3 cabin model. It was previously removed and all mounting hardware is gone as well. It is sitting in the middle and has a tendency to fall over during a port tack. looking for some help on how it is supposed to mount while still allowing access to bilge. Many thanks. Cheers.
