Time notes
- 0:04Correcting a D-class length errorChapter
A follow-up corrects the D-class length figures and shows why even familiar reference books need a second check.
- 1:49Checking feet-to-metre conversionsNotable Point
The reference book's feet measurements are sound, but several printed metric conversions are not, demonstrating how a trusted source can still introduce error.
- 3:47Recalculating the cruiser lengthsNotable Point
A live recalculation revises the comparative lengths used in the earlier episode, including one figure that had been overstated by more than ten metres.
- 5:54Hull form, power, and the speed questionNotable Point
The revised dimensions leave a half-knot speed puzzle among ships of similar weight and power, with propeller shape identified as a possible variable.
- 6:46Why corrections belong in teachingNotable Point
Reader feedback and a public correction become a practical lesson in checking measurements before using them in historical arguments.
