HMS Racer was a Decoy-class cutter launched at Sandgate on 24 April 1810.

[2] Lieutenant Daniel Miller had been ordered to patrol off the North Foreland to protect trade and annoy the enemy.

As Racer maneuvered toward the other one along the shore the leadsman called out depths ranging from six to eight fathoms.

When he called out five fathoms Miller had Racer put in stays, but it was too late and she grounded.

The court martial found that the leadsman had given false reports on the depth in order to cause the grounding.
