The Vulcan was poorly suited to maritime patrol

Was the Vulcan a good candidate for maritime patrol?

No; it consumed too much fuel and was designed for high-speed strike profiles rather than sustained low-altitude ocean patrol.

The Vulcan was designed for high-speed strikes against the Soviet Union and consumed a great deal of fuel. Its original mission used high-altitude approaches, followed later by low-altitude, high-speed profiles. Those requirements differed from sustained low-altitude ocean patrols. Its fuel consumption made it a poor candidate for maritime patrol.
