Great Lakes Sentry ST520M

Meet Sentry 520M 

The Great Lakes ST520M is a 17-foot aluminum-hull inflatable designed for everything from relaxed family cruising to tubing, swimming, fishing and full days exploring the lake.

With its wide 7'6" beam, spacious layout and capacity for up to 10 people, there’s plenty of room to bring the kids, friends, coolers and gear along for the day. The ST520M combines the stability and confidence of a large inflatable with the durability of a 4mm powder-coated aluminum hull.  A 20-degree deadrise helps provide a comfortable ride, while the large inflatable tubes make the boat exceptionally stable when passengers are moving around, swimming or climbing aboard. And when the kids want some excitement, the factory tow arch makes it ready for tubing and other family watersports. Whether you're heading across the lake for lunch, pulling the kids on a tube, finding a quiet beach for a swim or spending the afternoon fishing, the ST520M gives your family the freedom to do a little bit of everything.
