Lama Passage extends from Seaforth Channel to Fitzburgh Sound with Dryad Point across from Saunders Island at the junction. "Wood Island and Ark Island are close offshore at the junction of Seaforth Channel and Troup Passage. Newby Island, Munsie Point and Christiansen Point lie WNW of Ark Island. Nose Island, west of Christiansen Point, is steep-to on its south side and has a conspicuous tree about high."
Ivory Island with its lighthouse is the northwest entrance point to Seaforth Channel.

The area surrounding the Beazley Islands which lie southeast of Dearth Island and north of Nose Island, "is encumbered with numerous small islets and drying and below-water rocks."
The south shore of Seaforth Channel is not as irregular as the north side. After Athlone,
Dufferin, Horsfall and Campbell islands the channel makes a sharp turn to the passage between Campbell Island and Denny Island. It extends along Denny Island to the junction with Lama Passage between Hunter Island and Denny Island. The tug/barge that ran aground on Edge Reef off Athlone Island at the entrance to the Seaforth Channel in October 2016 was heading south.
Denniston Point on Dufferin Island, Idol Point on the south side of the channel and Bush Point are located on Seaforth Channel.

The inland passage refers to a coastal shipping route along a network of passages which weave through the islands on the
Pacific coast of North America from Alaska to Washington. Marine traffic prefers to use the inside passage when weather makes travel on the open Pacific Ocean more challenging. It is now a marine highway with cruise ships, freighters, tugs with tows, fishing craft and ships of the

By 1880, the shipping route that was "usually adopted by steamers and others desiring to make the inland passage from Queen Charlotte Sound to Dixon Entrance, is by way of Fitzhugh Sound, Lama Passage, Seaforth Channel, Milbank Sound, Finlayson and Grenville channels, and Chatham Sound

Lama Passage connected Seaforth Channel with
Fisher Channel. The Seaforth Channel and Lama Passage meet at the northern end of Campbell Island.
Marine traffic on the central coast prefer Seaforth Channel especially "when weather makes travel difficult further offshore."
On October 13, 2016, just after 1 a.m, a Texas-owned articulated tug/barge—a tugboat, the Nathan E Stewart, secured to the stern of an empty petroleum barge DBL 55—ran hard aground on the Edge Reef off Athlone Island at the entrance to Seaforth Channel

Although the Seaforth Channel is part of the Voluntary Tanker Exclusion Zone, the Nathan E. Stewart which is a U.S. vessel under 10,000 gross tonnage was allowed to operate by the Pacific Pilotage Authority, "without a local pilot on the West Coast of Canada." This is a common practice "if the crew meets a minimum standard of experience and licensing."

In 2011 when the Nathan E Stewart lost power and was set adrift in rough waters of Alaska, journalists at the time drew attention to the Pacific Pilotage Authority waiver that exempted the barge which makes routine weekly runs "between Vancouver and Alaska through the Inside Passage"

arrived on scene at 2:19 a.m. at CCG Station Bella Bella. They called in the Western Canada Marine Response Corporation (WCMRC) at 4:30 am and their vessels and crew from Vancouver and Prince Rupert arrived on site at 5:30 pm.
A "mobile skimming vessel, boom skiff, work boat, and tug, along with a total of 2,500 feet of boom" were on site.
The tugboat "settled under nine metres of water in Seaforth Channel." By October 26 the tanks of fuel on the submerged tug had been pumped out and "110,131 litres of an oil-water mixture" were recovered
but oil was discovered in at "least three coves in Seaforth Channel."
Bad weather prevented the salvage operation. Resolve Pioneer, a salvage vessel arrived in Bella Bella on November 8.
