what's with the foghorn that's all over this album?

could be an explicit homage

Phil loves Twin Peaks. Several songs on Wind's Poem are about the show

Are you aware of the follow-up, Mount Eerie?

The actual Mt. Erie is a frequent vacation spot for Phil since his childhood, located on an island off the coast of Anacortes, which like much of Washington's coastal cities features extensive maritime industry. Mt. Erie is necessarily reachable via ferry.

The town of Twin Peaks shares this maritime industry, especially considering its closeness to the Washington-Canadian border - though Twin Peaks is stated to be essentially landlocked (somewhere in the middle of the very top of the state), the area where it was filmed is located in the Seattle area (Snoqualmie Falls is the waterfall often seen in establishing shots), which is on the Snoqualmie River near the Puget Sound, where the river empties into the Pacific Ocean

So, in short, yes. Foghorns are typical in areas of maritime industry.
