Hood, Lancastria and Victory: which losses count as warship disasters?

Which Royal Navy warship loss held the deadliest-loss record before Hood?

The proposed warship comparison is the Victory lost in 1744. The much larger Lancastria loss in 1940 belongs to the troopship category, so the answer depends on the vessel types being counted.

Hood's loss is given as 1,415 crew in a comparison with earlier Royal Navy warship disasters. An initial suggestion names one of the battlecruisers lost at Jutland. Lancastria's 1940 loss, estimated here at 4,000 to 7,000 dead, introduces the importance of vessel classification. Her troopship role distinguishes that disaster from a warship loss, and the greater density of people aboard is contrasted with hospital-ship service. For the stricter warship category, the proposed comparison is the different HMS Victory lost in a storm in the English Channel in 1744. She is identified as a 100-gun ship of the line, although her captioned casualty figure is unreadable. Including troopships or fully loaded hospital ships changes the losses counted in such a comparison.
