"Britannia"s long gaff, the king’s chair, tiller, some mast hoops, blocks and rigging, anchor chain and clock are preserved in the Sir Max Aitken Museum in Cowes High Street and the remains of her spinnaker boom are at Carisbrooke Castle, also on the Isle of Wight. The spinnaker boom was given for use as a flag pole on the keep (where it twice suffered lightning damage), and the present flagpole is a fibreglass replica. In an episode of "Antiques Roadshow" from Pembroke Castle, broadcast in April 2017, a relative of a crew member brought photographs, and a damask tablecloth and some cutlery from the yacht, to be appraised.
