East Indiaman stats

[Diamondback]

Take a look at Jacques Boux's Pourvoyeuse class--two were built for the French Navy, don't recall if either was captured, then two more improved versions were commercially built, one became a merchant flute and the other Indien aka SCS South Carolina. Java and Guerriere were William Doughty iterating and improving on the existing Humphreys Superfrigate, a line of "evolutionary but not revolutionary" design development that continued until the move to steam power. Supposedly Humphreys was influenced by Indien in starting the Superfrigate design, but scaled it up and made a few proportional changes.

EDIT: My bad, working from memory, Pestel was a later engineer who his most memorable work was a variation in Sane's Hebe family tree.
