Accurate ENC vector data is now the backbone of US East Coast navigation. This region carries the full survey-grade ENC suite from Maine to Florida, including the Intracoastal Waterway's shoaling cuts and the notorious trouble spots — Hell Gate, the Chesapeake's crab-pot mazes, the shifting Georgia sounds — with depth-aware routing tuned to your draft.

Questions
Does this replace official paper charts?
It's built on the same survey-grade ENC vector data that's replacing paper charts, rendered as offline S-52 charts with depth-aware routing — so you carry the official-grade charts plus the planning tools.
Does it cover the whole ICW?
Yes — the Intracoastal Waterway from Norfolk south, including the cuts and shoaling stretches, with routing that respects your draft.
Will it work offline along the coast?
Yes — download once and the charts, tides and routing work with no signal, which matters in Maine fog and the remote Georgia sounds.
