USLHT Iris

USLHT Iris USLHT Iris was a United States Lighthouse Service tender launched in 1897 and operated along the Pacific Ocean seaboard and Alaskan waters during the late 19th and early 20th centuries. Built by Moran Brothers in Seattle, Washington, Iris served the United States Lighthouse Service alongside other tenders supporting lighthouses, lightships, and navigation aids during periods that overlapped with the administrations of Presidents William McKinley, Theodore Roosevelt, and Woodrow Wilson. The vessel's career intersected with events and organizations including the Klondike Gold Rush, the United States Revenue Cutter Service, and the expansion of maritime infrastructure in the Aleutian Islands.

Construction and design

Iris was constructed at the Moran Brothers shipyard in Seattle, Washington, a prominent West Coast yard noted for building vessels for the United States Navy, Alaska Steamship Company, and commercial operators serving routes to British Columbia, Nome, Alaska, and the Columbia River. The design reflected typical lighthouse tender features of the era: shallow draft for nearshore work, robust hull for seasonal ice, and deck cranes to handle buoys and supplies for stations such as Cape Flattery Lighthouse, Tillamook Rock Light, and remote installations in the Alexander Archipelago. Her steam propulsion and engineering plant were comparable to contemporaries like USLHT Mangrove and tended to the maintenance regime set by the Lighthouses Act of 1789 precedents adapted into United States maritime practice. Naval architects and shipwrights who worked at Moran Brothers had earlier built vessels for the Pacific Mail Steamship Company and components for Puget Sound Navy Yard contracts, influencing Iris's structural arrangements, compartmentation, and lifeboat complements.

Service history

Iris entered service with the United States Lighthouse Service based at regional depots that coordinated with the United States Coast Guard predecessor services including the Revenue Cutter Service and the Life-Saving Service. Her primary area of operation included the Pacific Northwest, Alaska, and the maritime approaches to the Bering Sea. Iris routinely provisioned lighthouses such as Point Reyes Light, Cape Mendocino Light, and facilities on Kodiak Island, transporting keepers, lamp oil, coal, and buoys. During the Klondike Gold Rush, Iris and other tenders supported increased maritime traffic to Dawson City supply routes and the Inside Passage, cooperating with commercial packet lines like Pacific Steamship Company and resupply efforts for U.S. Army posts in the region. Her logbooks recorded interactions with vessels from the North Pacific Steamship Company, White Pass and Yukon Route supply operations, and occasional coordination with the U.S. Navy during charting missions.

Notable operations and incidents

Iris took part in multiple search, rescue, and aid-to-navigation activities that brought her into contact with prominent locations and events. She assisted in post-storm repairs to aids near Shoalwater Bay and participated in buoy replacement after collisions involving merchantmen such as those trading with San Francisco and Victoria, British Columbia. Iris rendered assistance in coordination with the U.S. Life-Saving Service following grounding incidents near Columbia River Bar, sometimes interacting with Bar Pilot operations and the Pacific Mail Steamship Company fleet. During severe winters in the Aleutian Islands region she aided remote stations supplying lighthouses on Unimak Island and supported charting parties that worked with officers from the United States Hydrographic Office and civilian surveyors associated with the U.S. Coast and Geodetic Survey. Incidents recorded in period newspapers mention salvage coordination with commercial tugs from Seattle and involvement in regulatory matters under district superintendents appointed by the Treasury Department, reflecting the bureaucratic links between the Lighthouse Service and federal departments.

Decommissioning and fate

After decades of service, Iris was declared surplus as newer tenders and shifts in technology, including electrification of lights and diesel propulsion used by companies such as Puget Sound Navigation Company, reduced the operational need for older steam tenders. The vessel was sold in 1936 into civilian hands and removed from Lighthouse Service rolls as administrative changes consolidated aids-to-navigation responsibilities that later became part of the United States Coast Guard in 1939 under the Reorganization Act of 1939 context. Subsequent owners employed former tenders in coastal trade, freight, or conversion for fishing operations common among repurposed ships in the Pacific Northwest. The final disposition of Iris after sale followed patterns seen with contemporaries: conversion, renaming, or scrapping under yards such as Moran Brothers or shipbreakers active during the Great Depression, concluding a service life that intersected with major maritime developments involving entities like Alaska Packers Association, Northern Pacific Railway, and the maritime communities of Seattle, San Francisco, and Juneau.
