Overview
About this vessel
The 531 Fortress Wide Body (formerly known as the 511 Fortress Wide Body) is an open aluminium fishing boat within McLay’s Fortress range. At 5.3 m overall, it combines a wide-beam hull with high freeboard, delivering a very stable, soft-riding platform that has become a strong export seller, particularly to Australia and Europe.
Available in tiller, side-console or centre-console layouts (as a range), the Fortress series is built with heavy-gauge plate alloy, extensive underfloor and foam buoyancy to meet Australian and CE standards, making the boats virtually unsinkable. The 531 Wide Body is aimed at anglers seeking a tough, open layout with a strong emphasis on safety and durability.
