Detailed Report on AICW/Bogue Inlet Problem Stretch (St. M. 227) – Captains Mark and Diana Doyle Report
Posted by Claiborne | Posted on 07-22-2012
Here’s another excellent report from our strategic partners, Captains Mark and Diana Doyle, owners and originators of On The Water Chart Guides. This article concerns the “AICW Problem Stretch” found at the intersection between the Waterway and shallow Bogue Inlet, hard by the community of Swansboro, North Carolina.
The real surprise here is that Diana and Mark discovered one stretch (see below) that promises only 6.3 feet at MLW. Sure, that’s barely enough for most cruising craft now, but what if more shoaling occurs. Clearly, this stretch bears close monitoring as time goes forward!
Diana and I transited northbound by Bogue Inlet, NC June 21st, near high-tide and rising. The relevant tide station, Bogue Inlet, has a Spring Tidal Range (STR) of 2.6 feet. Our plan was to transit, strictly surveying the Magenta Line, but honoring any navaids.
The screenshot shows the approach with slightly varying, but good depths (15-19 feet at 1.7 feet above MLLW).
Near the ICW-Bogue Inlet junction there was a rapid drop before G45A to under 10 feet (at 1.7 feet above MLLW).
Transiting the junction soundings quickly climbed and held varying but good depths (13-20 feet at 1.7 feet above MLLW).
Past the junction, there was another slight dip in depth (12-13 feet at 1.7 feet above MLLW), followed by increasing and more consistent depths (15-19 feet at 1.7 feet above MLLW).
Our course line was steady, along the Magenta Line, presumably marking the deepest water.
A few observations on the ICW-Bogue Inlet junction:
1. There currently appears to be only one shallow spot along the Magenta Line portion of this area, as shown in the screenshot.
2. This shallow spot, near G45A, (around 8 feet at 1.7 feet above MLLW) will be a bit of a nail-biter for keel boats or power boats with deeper draft.
3. However, with all of the other soundings above 12 feet, at this height of tide, Bogue Inlet currently seems to be a reasonably safe area to transit, along the Magenta Line, even near low water.
Again, no recommendation being made here. Just sharing data. Captains are responsible for their decisions and outcome.
Best and see you On the Water,
Captains Mark & Diana Doyle
