BARTLETT COVE, ALASKA – Glacier Bay National Park and Preserve Acting Superintendent Joni Seay announced today that the 13-knot vessel speed limit is being removed from Whidbey Passage. Recent observations reveal that few humpback whales are feeding consistently in this area. In addition, the lower West Arm whale waters area is being replaced by a 13-knot speed limit around Lone Island, Geikie Rock, Hugh Miller Rocks, Blue Mouse Cove, and Jaw Point to protect whales feeding in these specific areas. These updated operating requirements are effective from 5 AM Thursday July 17th until further notice.

Lower Bay whale waters:

• The Lower Bay whale waters will retain a 13-knot vessel speed limit.
• Vessels over 18 ft in length are required to remain at least 1 nautical mile from shore or mid-channel.

New whale waters:

• A 13-knot vessel speed limit in all waters within 1 nautical mile of Lone Island, Geikie Rock, Hugh Miller Rocks, the unnamed island just south of Blue Mouse Cove, and Jaw Point.

Speed and course restrictions in whale waters are intended to reduce the disruption of feeding humpback whales and to lower the risk of whale/vessel collisions, as authorized by Title 36 of the Code of Federal Regulations, Subpart N, 13.1174. In all Park waters, vessels are prohibited from operating within ¼ nautical mile (0.25 nautical mile) of a humpback whale. If a vessel is accidentally positioned within ¼ mile, the operator must immediately slow the vessel to 10 knots or less and alter course away from the whale until at least ¼ mile separation is established. Vessels should proceed cautiously in all areas where whales may be present. Whales may surface in unexpected locations, posing a hazard to both the vessel and the whale. Boaters are advised to verify whale waters designations prior to entering Glacier Bay by telephoning [phone] or by contacting KWM20 Bartlett Cove on marine VHF radio.
