The Umbrella Cut Route northbound takes you from Mile 696 in Cumberland River through Floyd Creek, across the Satilla River and into the Little Satilla to rejoin the AICW at Mile 686 in Jekyll Sound. This is often considered the route of choice when the primary passage which passes through St. Andrew Sound, and almost out into the briny blue, is kicking up.

We used the alternate route on 9/19 heading south. We entered Umbrella Cut at almost exactly mid tide, according to the tide chart, but more likely equivalent to about 2/3 high tide due to a strong NE wind and our observations. We traveled at about 7-8 kts all the way through and took about an hour. Our depth readings were 10′ at A5 and A6 at the entrance to Umbrella Cut, the lowest on the whole route of 5.5′ at A10, 8.5′ at A24 to A26, and 7.5′ just south of A26.
Our boat is a 44′ long Endeavour TrawlerCat with a 3′ draft.
