Were guillotines installed aboard French Revolutionary warships?

Did French Revolutionary warships carry guillotines?

The answer considers it unlikely and gives no confirmed shipboard example.

The reply considers the answer probably no, while acknowledging that the idea has attracted interest. It supplies no specific ship with a guillotine. The discussion contrasts the guillotine's intended reduction of suffering with the exemplary and deterrent purposes attributed to naval executions. That comparison is an explanation of historical punitive thinking, not an endorsement of it.
