Dive Site Overview
Initially named DM-One, the vessel began its operational life in Hamburg, Germany, in 1966. Spanning 225 feet (68.6 m), this ship served a lengthy career under various names, primarily transporting general and grain cargo across international waters.
Its journey to becoming an artificial reef started in October 2013, when the MCAC Artificial Reef Fund acquired it for transformation into the Hailey Glasrud Artificial Reef. On April 24, 2014, the controlled deployment occurred, meticulously managed and described by observers as a "picture perfect day." Careful planning ensured the ship settled precisely upright on the seabed, intentionally establishing a new "hotel for fish" and a complex ecological foundation.
Now positioned 8 miles off Martin County, Florida, it functions as a substantial underwater structure, offering a complex environment for diverse marine life. This endeavor stands as a testament to Florida's robust artificial reef program, actively enhancing marine ecosystems and bolstering coastal tourism through such projects.
A successful sinking has provided divers with an unparalleled opportunity to explore a significant piece of maritime history, repurposed for ecological benefit and offering intricate environments. It continues to evolve as a vibrant habitat, attracting a wide spectrum of marine species and contributing to local biodiversity.
Best Time to Dive
Planning a dive to Glasrud Reef typically yields the most favorable conditions from late spring through late summer. May, July, and August often present optimal dive scores due to calmer seas and pleasant air temperatures. During these months, average air temperatures range from 26.0°C (78.8°F) in May to 28.7°C (83.7°F) in August. Rainfall is also comparatively lower, with July averaging around 2.9 mm and August around 3.3 mm, reducing potential runoff that can impact visibility. While October experiences cooler air temperatures around 26.4°C (79.5°F), it also shows a higher average rainfall of 6.0 mm and increased wave heights, potentially affecting surface conditions and dive comfort. For the best experience, target the months with lower average wave heights and consistent warm air.
