Would Britain support an American blockade of Spain?

If Britain permitted an American blockade of Spain, would it provide dockyard services or ships?

Dockyard services would be the likely support, but Britain was unlikely to permit the blockade because of its political consequences.

Dockyard services would be the likely British contribution if London accepted an American blockade of Spain. Allowing the operation would create too many political difficulties for Britain, so even permission for the blockade is judged unlikely.
