Why the RAF's fleet-bombing opportunity disappeared

Did the RAF consider using massed heavy bombers against the German fleet?

It tried naval bombing early, but the German fleet target had largely disappeared by the time the heavy-bomber force matured.

The RAF did more than consider mass attacks on German naval forces. It attempted such operations early in the war when its means and accuracy were limited. The mature heavy-bomber force arrived later. By then the German surface fleet was no longer available as the same concentrated target, so capability and target timing never aligned cleanly.
