957 — Trigg

WA Department of Transport Nautical Chart

Large-scale inshore navigation for reefs, lagoons, and one of Perth’s most active coastal boating zones.

🚤 Navigate Trigg with Local Authority Confidence

Chart 957 — Trigg is a detailed nautical chart published by the Western Australian Department of Transport to support safe recreational and local commercial boating along Perth’s central coastline around Trigg.

This section of coast is defined by fringing reefs, shallow lagoons, popular launch points, and heavy recreational traffic. The chart delivers the large-scale clarity skippers need when operating close to shore—where reef edges, depth changes, and navigation aids matter most.

🧭 Why Skippers Rely on This Chart

• ⚓ Authoritative WA source — Published by the Department of Transport

• 🗺️ Large-scale detail (1:25,000) — Ideal for reef and inshore navigation

• 🚦 Navigation aids clearly shown — Lights, beacons, piles & limits

• 🌊 Depth soundings & seabed detail — Essential around reefs and shallow margins

• 🚤 Hazard awareness — Helps avoid groundings in busy near-shore waters

🧠 Why Trigg Needs a Dedicated Chart
