While visiting the TBT Engineering Consulting Group, be sure to stop by the display of model ships built by Dave Benedet. From tugs to freighters, many of which reflect familiar visitors to Thunder Bay’s harbour, Benedet has constructed 154 model ships over his lifetime. A retired ship’s engineer, Benedet can also share many stories of sailing Lake Superior and beyond.
