Given the following context:

A USCG pilot and his winchman Haig answer an SOS call at sea and arrive at a derelict schooner, the Requite. Haig lowers himself to the ship, where he finds three dead bodies along with one survivor, Eva, cowering in the cabin.
As the pilot attempts to retrieve Haig and Eva with a rescue basket, the line breaks, plunging the two into the ocean.  After they swim back to the boat, the pilot informs Haig that he must return to base because his fuel is borderline.  Eva and Haig spend the night on the boat, during which time she recounts the story of the storm that killed everyone else aboard. She explains to him that the strange events began soon after they found a priest drifting in the ocean, apparently a survivor of a disaster. Then, she tells Haig of the violent storm that caused all of the freakish deaths on the boat. One man was hurled through a hatch; one is hanging from the ship's mast; another vanished before her eyes; and a fourth man is in an aft compartment, floating in the air.
Eva attributes the deaths to supernatural causes, but Haig has a practical explanation for everything, including the man who appears to be floating in the air.  Early the next morning, the pilot returns along with the Coast Guard cutter Venturous.  Haig and Eva are transferred from the Requite to the deck of the Venturous, where they board the helicopter for the flight back to Miami.  At the same time, Coast Guard personnel from the Venturous investigate the wrecked schooner.
The story takes a bizarre turn when the Venturous' captain calls Haig to tell him that what they found on the ship was not what Haig reported. Right after Haig hears about the discovery, another nightmare begins. The film is an example of a twist ending.

answer the following question:

What coast guard cutter saved Haig and Eva from the Requite? 

Venturous
