Viking Octantis Threads the St. Clair Among the Ore Boats

Viking Octantis was downbound through the St. Clair corridor at 05:22 this morning, ETA at Port Huron logged at 06:27. She is not a laker. She is an expedition cruise vessel, the kind fitted out for polar ice and adventure passengers, and she has no business looking like she belongs between Edwin H. Gott and Herbert C. Jackson on a Thursday morning in August. But there she was.

Gott was upbound off Detroit River Light at 05:05, her ETA at Port Huron set for 12:02. Herbert C. Jackson was at Grassy Island as of 04:28, ETA Port Huron 10:51. The two American flaggers were climbing the St. Clair in the dark while Octantis came down toward them. Three vessels, two directions, one narrow channel, before most of the dock crowd had poured a first cup.

Viking Octantis is the vessel worth watching from the bank today. She photographs differently than the ore boats, and she does not come through this corridor on any fixed schedule.

Harbor Notes

Hon. James L. Oberstar was upbound between DeTour and the Soo at 04:40 this morning, ETA at the locks 08:11. She was the freshest upbound name in the Soo queue at that hour.

Harvest Spirit was downbound past the Keweenaw at 01:34, ETA at the Soo 14:03. If she held speed and cleared the locks near that window, she is on Lake Huron by Friday morning.

Manitowoc was upbound from South East Shoal in Lake Erie at 05:48, ETA at Detroit 10:38. Three vessels bound for the Welland, Federal Montreal, Mrs C, and Algoma Buffalo, were all reported at Port Weller in the early hours of August 6, entering the canal within roughly an hour of each other.

The tug Harriet M, formerly the American tug Harriet Moran, was reported making her first Seaway transit after purchase by an as-yet-unnamed Canadian company, bound for Sault Ste. Marie, Ontario, as of August 5.

The Levels Ledger

Lake Ontario leads the system at 3.73 feet above Low Water Datum at Rochester. Lake Erie follows at 3.08 feet at Cleveland. Lake Michigan reads 2.24 feet at Chicago, Lake Huron 2.10 feet at Harbor Beach, and Lake Superior sits lowest at 1.75 feet at Sault Ste. Marie. Vessels loading taconite on Superior are working with the tightest margin in the system; every inch of draft matters on a full ore load bound downbound through the Soo.

Weather on the Water

Lake Huron is the unsettled lake today. A slow-moving cold front is stalling across the southern Great Lakes this morning, producing showers and isolated thunderstorms through the day; wave heights on Huron are at two feet. Lake Erie is also running at two feet under a trough sitting just northwest of the lake. Superior, Michigan, and Ontario are all at one foot. Patchy fog was possible on Michigan this morning under light winds and should ease as a light southerly develops tonight.

Looking Astern

The Harriet M story has a historical note behind it: a working tug crossing from American to Canadian registry and entering the Seaway under a new name and an unidentified owner is the kind of transaction that takes years to fully document. The vessel was known as Harriet Moran in American service. Her new Canadian owner had not been named as of the August 5 report. Until she ties up at the Canadian Soo and someone signs a manifest, her intended Great Lakes trade remains an open question for the record books.

Tomorrow's Watch If *Harvest Spirit* cleared the Soo Locks near her 14:03 ETA today, watch for her stack at the Harbor Beach gauge on Lake Huron between dawn and mid-morning Friday, August 7.

Vessel Spotlight: *Viking Octantis* was downbound through the St. Clair corridor at 05:22 this morning with a Port Huron ETA of 06:27, threading between upbound lakers *Edwin H. Gott* and *Herbert C. Jackson* in the pre-dawn hours. An expedition cruise vessel among ore boats is not a common sight in this channel, and she carries no fixed schedule to predict when she will come through again.
