Tugboat Tessie is the owner and captain of the tugboat Harbor Lady, based out of major shipping port. She is an older woman, having an grown daughter that serves as her first mate on the tug, but still well into her prime and quite strong and physically imposing. Tessie often finds herself having to deal with lots of unsavory characters along the waterfront. Criminals and con men litter the area like floatsom on the tide. Thankfully Tessie's strength, her mean right hook, and her skill as a tugboat captain serve her pretty well to help keep the harbor safe.
