Thought it would be a good idea to moose hunt in a September flood tide in 1984, up the Little Susitna River starting at Port of Anchorage and running across the Cook Inlet! In one of those narrow bow 17 ft Grizzly boats with the little inboard 2 strokes! Used up about 1/2 our fuel trying to find the Little Sue in the braided inlet! Made it in the river went quite a ways upstream and anchored up.
About midnight we were drifting back into the inlet with flood logs and debris no lights, got the boat going and went back upstream in a flood tide, to a tidal gut and re anchored. Tidal guts are narrow and steep but do not look that way when tide is in, bottom nothing but silt, think quicksand, you cant step out of the boat, big mistake.
Spent 6 lovely hrs when the boat went hi and dry at an angle where we had to brace ourselves to keep from sliding, lots of fun, then 6 more hrs waiting for the tide wondering if the narrow stern would float or swamp. Boat floated and we went home, have not been back in the upper Cook Inlet since 1984!
Native boats that run those waters are wide in the stern and bow to refloat if boat goes hi and dry, ours was not!
Flood tides in the Cook inlet can exceed 32 ft second highest in the world as I recall.
