ᐃᒡᓗᐊ Navy Board Inlet is a significant, 113-kilometer-long saltwater inlet in Nunavut's Qikiqtaaluk Region, forming part of Sirmilik National Park. It separates Baffin Island from Bylot Island, ranging from 10 to 29 kilometers in width. The inlet serves as an arm of Lancaster Sound, connecting southerly to Eclipse Sound. The primary access point for paddlers is the community of Pond Inlet, located on the northeastern coast of Baffin Island directly on the shores of the inlet. This hamlet provides the essential gateway for any expedition. The scenery is impressive, with views across the iceberg-strewn channel to the mountains and glaciers of Bylot Island. Several glaciers descend abruptly to the shoreline just north of Low Point. The inlet contains a few islands, including the Wollaston Islands.

Paddling here is an expedition-level undertaking reserved for the extremely experienced. The high Arctic environment presents severe and immediate hazards. Water temperatures are lethally cold year-round, making a dry suit an essential piece of safety equipment, and any immersion carries grave risk. Conditions are dynamic and dangerous; Eclipse Sound, to which the inlet connects, is often covered by pack ice until mid-summer. Travel can be hazardous due to strong winds, currents, and high waves that can whip up quickly. Paddlers must be proficient in advanced skills including surf landings and launches, self-rescue, and navigation in fog using marine charts and tide tables. Group size must be sufficient for mutual rescue. The area is a productive marine ecosystem, home to narwhals, polar bears, seals, and whales, and is part of the main marine transportation route, indicating the potential for boat traffic. The best window for paddling is likely limited to the brief summer period when ice recedes, with average temperatures between 7 and 10 degrees Celsius and extended daylight.
