Like most other boats we have dedicated storage spaces for plates and glassware.
To protect them from breakage on passage, we use stubby coolers for wine glasses and special covers for champagne glasses. Plates are protected via in-between layers of rubber mats, cut to the diameter of each plate. Those non-slip materials are easily cut with standard scissors and are easily available from your local hardware store by the meter or from your chandlery. The plates themselves are stored in a cabinet with adjustable spacers to suit each stack of plates.
For the silver cutlery we’ve used special dividers glued into place in a drawer which keeps the pressures fork and knifes in good shape and in place at any state of sea or turbulence.
