The fishing vessel Odin sprung a leak while shrimping off the coast of Port Mansfield, Texas.   The three men on board the Odin contacted the Coast Guard that the vessel was taking water through the propeller shaft and was in danger of sinking.   The Coast Guard dispatched a Dolphin rescue helicopter to the scene.    The helicopter successfully lowered two dewatering pumps to the Odin.   With the pumps running, the Odin was able to stay afloat.   The fishing vessel Gina Dawn also came to the aid of the Odin.  The Gina Dawn took the Odin under tow and proceed back to port.   No reports of injury.
