Newry Island Sailing Guide. Newry Island is the principal island of the Newry group, sitting north‑west of Mackay and south of St Bees and Keswick. It is low, rocky, and heavily reef‑fringed, with a single reliable anchorage on its western side and several narrow fair‑weather pockets nearby. The island is used primarily for short‑stay shelter, day visits, and staging for vessels moving between Mackay and the Cumberland Islands. There are no facilities, and all anchorages are used solely for overnight shelter.
The underwater profile around Newry Island is shallow compared to the offshore islands, with offshore depths of 12–18 m reducing to 6–10 m near the shoreline. Inside the anchoring zone, depths settle into 4–7 m over firm sand. Fringing reef rises from 2–4 m into the reef flat, restricting swing room and narrowing anchoring bands. The western side provides the only reliable shelter in SE–E winds, while the eastern side is exposed and only workable in calm conditions.

Sailing Guide Approaches
Newry Island lies close inshore north of Mackay and forms the central anchorage of the Newry Islands group. The island’s western bay provides the most dependable holding, with clean sand patches and predictable depth gradients. Offshore depths remain consistently 12–18 m, reducing to 6–10 m near the shoreline. Inside the anchoring area, depths sit in 4–7 m over sand. The eastern side is exposed to swell and unsuitable except in light conditions.

Sailing Guide - Western Bay
(Primary Anchorage)
The western bay of Newry Island is the main anchorage and the most reliable in the group. Approaches are simple, with offshore depths of 12–18 m reducing to 6–10 m as you close the shoreline. Inside, anchoring depths sit in 4–7 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 points.
The bay provides good protection in SE–E winds, with minimal swell intrusion. It becomes exposed in N winds and develops a light roll in SW winds depending on swell direction. Swing room is moderate but limited by fringing reef rising from 2–4 m on both points. Dinghy access is straightforward at mid‑to‑high tide, with 1–1.5 m at the shoreline.

Sailing Guide - North‑West
Pocket (Secondary Anchorage)
A small pocket on the north‑western side provides a workable anchorage in moderate conditions. Offshore depths of 12–16 m reduce to 6–8 m near the shoreline. Inside, anchoring depths sit in 4–6 m over sand with isolated coral. The fringing reef rises from 2–4 m, and coral heads lifting into 1–2 m are scattered across the northern margin.
This pocket is workable in SE–S winds but becomes exposed in W–N winds. Swing room is limited, and the anchorage is best suited to smaller vessels. Dinghy landing is possible at mid‑tide, though reef shelves restrict access at lower water.

Sailing Guide - South‑West
Shelf (Fair‑Weather Only)
A narrow shelf on the south‑western side provides a small fair‑weather anchorage. Offshore depths of 14–18 m reduce to 6–10 m near the shoreline. Inside, anchoring depths sit in 3–5 m over sand with isolated coral. The fringing reef rises from 2–4 m, and coral heads lifting into 1–2 m are common.
This anchorage is workable only in light SE–S winds and becomes untenable in W–N winds. Dinghy landing is limited by reef shelves.
Newry Island
Sailing Guide - Eastern Side
(No Anchorage)
The eastern side of Newry Island is exposed to swell and unsuitable for anchoring. Offshore depths of 14–20 m reduce to 6–10 m near the reef edge, but the seabed drops steeply and anchoring bands are extremely narrow. Fringing reef rises from 2–4 m, and coral heads lifting into 1–2 m are common along the eastern margin. This side is used only for transit.

Sailing Guide - Navigation
Notes
Navigation around Newry Island is straightforward but requires attention to shallow reef shelves and narrow anchoring basins.
Depth and Seabed
- Offshore depths: 12–18 m
- Near‑shore depths: 6–10 m
- Anchoring depths: 3–7 m over sand
- Fringing reef: 2–4 m, extensive around all points
- Coral heads: 1–2 m, common near headlands
Operational considerations
- Tidal streams are weak, with mild cross‑set near the northern approaches.
- Reef edges are easy to identify in settled conditions.
- Low sun angles can obscure coral heads; late‑day arrivals require caution.
- Swing room is limited in all anchorages; conservative scope is recommended.
- The safest entry line is a central approach into the western bay.

Sailing Guide - Weather
The Newry Islands are influenced by the SE trade‑wind regime, with winds commonly 15–22 knots during the season.
- Best shelter: Western Bay
- Moderate shelter: North‑West Pocket
- Fair‑weather only: South‑West Shelf
- Exposed: All anchorages in N winds
- Swell: Minimal on western side; immediate intrusion on eastern side
- Tidal range: Moderate, with weak streams
Western Bay remains comfortable in SE–E winds, while all anchorages become exposed in N winds.

Newry Island
Sailing Guide - Summary
Newry Island provides the most reliable anchorage in the Newry group, with clean sand bottoms, predictable depth profiles, and workable shelter in SE–E winds. The western bay is the primary anchorage and the only consistently usable option, while the north‑west pocket and south‑west shelf are strictly fair‑weather. The eastern side is exposed and unsuitable for anchoring. Newry Island functions as a practical short‑stay stop for yachts transiting between Mackay, the Cumberland Islands, and offshore GBR routes.
