I was on Mawana in that same Atlantic storm and heard the radio traffic. We were well south of the Manipur. It appears that Sceptre is still maintained by her own society.

Sceptre returned home in October, aboard the freighter Manipur which unfortunately ran into a gale, during which the yacht’s cradle broke. Sceptre fell against a ventilation pipe, damaging her hull and a hatch, and putting her future in some doubt. This event is remembered by Andrew Parks:
She was stowed in a cradle on our after deck. Not surprisingly, the cradle was very high and there were beams right across Sceptre's deck whereby she was secured downwards to the ship. However, when Manipur rolled heavily in the storm after leaving New York it became evident that the cradle was not adequate for such sideways stresses and one side collapsed. Sceptre fell across the deck onto a ventilator and her bow was damaged. When we diverted to Halifax Nova Scotia to have Sceptre re-secured it made TV news here in Britain.
