Inconstant was a Sylphe-class brig, one of 32, launched in 1811 for the French Navy. In 1815, Napoleon used her to escape from exile on Elba. In the 1820s she took part in the war with Spain and later served on the Brazil station. She also served on the French Guiana station. She was broken up at Brest in December 1843.

The Abeille class was a type of 16-gun brig-corvette of the French Navy, designed by François Pestel with some units refined by Pierre-Jacques-Nicolas Rolland. They were armed with either 24-pounder carronades, or a mixture of light 6-pounder long guns and lighter carronades. Twenty-one ships of this type were built between 1801 and 1812, and served in the Napoleonic Wars.
