Shotline Diving is proud to introduce the updated 2025 3D model of the Sidewheeler Sea Bird — a 192-foot wooden passenger steamer whose tragic loss off Waukegan, Illinois remains one of the deadliest maritime disasters in southern Lake Michigan.
Built in 1859, Sea Bird was designed for passenger service during the height of Great Lakes expansion. On her final voyage, she caught fire and burned before sinking offshore. Historical accounts indicate that between 72 and 100 passengers and crew perished, with only three known survivors. The wide casualty range reflects conflicting contemporary reports, a reminder of how chaotic and poorly documented many 19th-century disasters were.
The wreck was discovered decades later by noted shipwreck hunter Harry Zych, bringing renewed attention to the vessel and its story.
The 2025 Model Update
This newly released model represents a major step forward in documenting the site through no-touch, high-resolution photogrammetry.
- 1,389 individual images
- 30-megapixel resolution
- Captured during the 2025 dive season
- Photogrammetry by Andrew Goodman
The result is a remarkably detailed digital reconstruction of the wreck site, preserving it virtually while leaving it physically undisturbed.

Why This Matters
The Sea Bird rests as both a maritime time capsule and a gravesite. High-resolution 3D modeling allows researchers, historians, and the public to examine hull structure, machinery remnants, and site layout without disturbing the wreck.
At Shotline Diving, we strongly support and practice NO-TOUCH documentation methods. The wreck is protected under state law, and artifact removal without permits is illegal. Our mission aligns with a simple principle:
Leave only bubbles, take only memories.
Be the diver that makes a difference.
Digital preservation ensures these sites remain intact for future generations while expanding public access to Great Lakes maritime history
