4099 Nautical Chart: Sable Island (Western Portion) | Official CHS Marine Chart

Navigate one of the most storied and hazardous regions of the North Atlantic with the Official CHS Chart 4099. This specialized coastal chart provides high-detail coverage of the Western Portion of Sable Island (Île de Sable), a remote crescent of sand known as the "Graveyard of the Atlantic."

As a genuine Canadian Hydrographic Service (CHS) publication, Chart 4099 is a critical tool for mariners transiting near this shifting sandbar. At a precise scale of 1:100,000, it offers the authoritative bathymetry and shoreline data required to navigate the island’s treacherous, submerged sandspits and unpredictable currents. Because Sable Island is a protected National Park Reserve, this chart is not only essential for safety but also for ensuring compliance with maritime boundaries in these ecologically sensitive waters.

Key Features include:

• Focused Island Detail: Precision mapping of the western reaches of Sable Island, where shifting sands can alter depths rapidly.

• Official Data Accuracy: Compiled by the CHS and regularly updated to meet all Canadian maritime safety and carriage requirements.

• Hydrographic Precision: Features clear depth soundings, seafloor contours, and the exact locations of offshore shoals and submerged hazards.

• Sable Island Bank Navigation: Essential for commercial shipping, offshore research, and search and rescue operations in the Atlantic.
