The U.S. Coast Guard is asking mariners to avoid the Woods Hole passage and to be cautious navigating southeastern New England waters after two fishing vessels were trapped in ice this weekend around the Vineyard.

According to press releases by the Coast Guard, a 69-foot fishing boat named Misty Blue became stuck in ice north of the Quick’s Hole passage on Friday morning, with a three-person crew on board.

Quick’s Hole is a narrow passage between Pasque and Nashawena islands and connects Buzzards Bay to Vineyard Sound.

Watchstanders at Coast Guard Sector Southeastern New England were notified about the ship at 10 a.m., and the Coast Guard’s aids to navigation team in Woods Hole launched a 49-foot Stern Loading Buoy Boat. The team broke the Misty Blue out of the ice at about 11:30 a.m. and escorted the fishing boat back out to sea.

According to U.S. Coast Guard vessel documentation online, the Misty Blue hails from Barnstable and is owned by BC Bait Company Inc.

On Saturday afternoon, the Coast Guard said, the fishing boat Capt. RM Chase became lodged in ice in Woods Hole passage while returning to New Bedford. A member of the four-person crew notified Coast Guard watchstanders at about 3 p.m.

The aids-to-navigation team was breaking ice nearby aboard the buoy boat and came to help free the fishing boat from ice, the Coast Guard said. The Capt. RM Chase was freed by 3:30 p.m.

On Monday, Capt. J.T. Kondratowicz said in a marine safety information bulletin that boaters are advised to avoid Woods Hole passage, which has been “severely impacted” by ice.

“Vessels should consider alternate routes when transiting between Buzzards Bay and Nantucket Sound,” he said.

Navigation aids are off-station or submerged in most federally-maintained waterways, the bulletin said, making channels difficult to pass. The Coast Guard recommends that vessels limit travel to daylight hours when visibility is at least one nautical mile.

While Coast Guard cutters are working on ice-breaking in area waterways, Capt. Kondratowicz said, ice thickness in several areas exceeds the vessels’ capabilities. Mariners are report maritime emergencies or sightings of severe ice that impacts navigation to the Sector Southeastern New England Command Center at VHF channel 16 or 508-457-3211.
