Middle Percy Island Sailing Guide
Middle Percy Island sailing guide. Middle Percy Island is the cultural and operational centre of the Percy Islands, sitting between North Percy and South Percy and forming the most visited anchorage on the offshore route between the Whitsundays and the Capricorn Coast. The island is steep, rugged, and heavily reef‑fringed, with a single outstanding anchorage—West Bay—on its western side. The eastern and southern sides are exposed to Coral Sea swell, with steep drop‑offs and narrow reef shelves. Middle Percy is uninhabited except for the caretaker presence at West Bay, and all anchorages are used solely for overnight shelter, staging, and weather waiting.
The underwater profile around Middle Percy is deep and abrupt, with offshore depths of 24–40 m reducing to 12–18 m near the shoreline. Inside the anchoring zone, depths settle into 6–12 m over firm sand. Fringing reef rises from 3–6 m into the reef flat, restricting swing room near headlands. West Bay provides the only reliable shelter in SE–E winds, while all other sides of the island are exposed and only workable in calm conditions.
Middle Percy Island Sailing Guide
Middle Percy Island lies south of North Percy and north of South Percy, forming the central and most sheltered anchorage in the group. West Bay is the signature anchorage—wide, deep, and well protected from the trade‑wind regime. Offshore depths remain consistently 24–40 m, reducing to 12–18 m near the shoreline. Inside the anchoring area, depths sit in 6–12 m over firm sand. The eastern and southern sides are steep, reef‑bound, and unsuitable except in light conditions.
West Bay (Primary Anchorage – Western
Side)
West Bay is the main anchorage on Middle Percy and one of the most iconic anchorages on the Queensland coast. Approaches are straightforward, with offshore depths of 24–34 m reducing to 12–16 m as you enter the bay. Inside, anchoring depths sit in 6–12 m over firm sand, with the central basin offering the cleanest holding. The seabed slopes gently toward the beach, and the anchorage remains mostly free of coral except near the northern and southern headlands.
West Bay provides excellent protection in SE–E winds, with the high ridges of Middle Percy blocking both wind and swell. It remains comfortable even in strong trade‑wind conditions. It becomes exposed in N winds and develops a light roll in NW–W winds depending on swell direction. Swing room is generous, and the bay can accommodate multiple vessels. Dinghy access is straightforward at all tides, with 1–1.5 m at the shoreline.
North‑West Pocket (Secondary Anchorage – Fair‑Weather Only)
A small pocket on the north‑western side provides a secondary anchorage in calm conditions. Offshore depths of 26–34 m reduce to 14–18 m near the shoreline. Inside, anchoring depths sit in 8–10 m over sand with isolated coral. The fringing reef rises from 3–6 m, and coral heads lifting into 2–3 m are scattered across the northern margin.
This pocket is workable only in light W–SW winds and becomes untenable in any SE–E wind. Dinghy landing is limited by reef shelves.
Eastern Side (No Anchorage)
The eastern side of Middle Percy is fully exposed to Coral Sea swell and unsuitable for anchoring. Offshore depths of 30–40 m reduce to 16–20 m near the shoreline, but the seabed drops steeply and anchoring bands are extremely narrow. Fringing reef rises from 3–6 m, and coral heads lifting into 2–3 m are common along the eastern margin. This side is used only for transit.
Southern Side (Transit Only)
The southern side is steep, exposed, and not suitable for anchoring. Offshore depths of 26–34 m drop quickly into deeper water, and the fringing reef rises abruptly from 3–6 m. Swell wraps around the headlands in SE–E winds, and the shoreline offers no protection. This area is used only for transit between Middle Percy and South Percy.
Middle Percy Island Sailing Guide - Navigation
Notes
Navigation around Middle Percy Island is straightforward but requires attention to reef shelves and steep depth transitions.
Depths and Seabed
- Offshore depths: 24–40 m
- Near‑shore depths: 12–18 m
- Anchoring depths: 6–12 m
- Fringing reef: 3–6 m, extensive around headlands
- Coral heads: 2–3 m, common in fair‑weather pockets
Operational considerations
- Tidal streams are moderate, with noticeable set between the islands.
- Reef edges are easy to identify in settled conditions.
- Low sun angles can obscure coral heads; late‑day arrivals require caution.
- The safest entry line is a central approach into West Bay.
Approaches from both the Whitsundays and Shoalwater Bay are deep and unobstructed.
Middle Percy Island Sailing Guide - Weather
Middle Percy Island is strongly influenced by the SE trade‑wind regime, with winds commonly 15–25 knots during the season.
- Best shelter: West Bay
- Fair‑weather only: North‑West Pocket
- Exposed: All anchorages in N winds
- Swell: Minimal on western side; immediate intrusion on eastern side
- Tidal range: Moderate, with predictable streams in inter‑island channels
West Bay remains comfortable even in strong trades, making it one of the most reliable offshore anchorages on the central Queensland coast.

Middle Percy Island Sailing Guide - Fishing
Middle Percy offers the most accessible fishing in the group thanks to the mix of reef, sand patches, and current lines wrapping around the island. West Bay itself isn’t a hotspot, but the points north and south of the anchorage hold small coral trout, sweetlip, and cod on the broken reef, with bait often pushed tight to the rocks on the flood. The eastern side is far more energetic, clear water, strong flow, and a sharper drop‑off that regularly produces Spanish mackerel, trevally, queenfish, and longtail tuna working the pressure edges. The southern end toward Pine Islet sees good pelagic movement on tide changes, especially when the bait schools stack along the contour. As with the rest of the region, skippers favour smaller reef fish and pelagics due to ciguatera risk in larger specimens. Overall, Middle Percy rewards mobility: short drifts, lure passes along the point, and working the tide lines rather than sitting at anchor.
Middle Percy Island Sailing Guide - Summary
Middle Percy Island provides one of the most dependable anchorages in the Percy Islands, with clean sand bottoms, predictable depth profiles, and strong protection in SE–E winds. West Bay is the primary anchorage and the cultural centre of the region, while the north‑west pocket is strictly fair‑weather. The eastern and southern sides are exposed and unsuitable for anchoring. Middle Percy functions as a key overnight stop for yachts transiting between the Whitsundays, the Cumberland Islands, Shoalwater Bay, and the Capricorn Coast.
