This remains an issue with numerous 7′MLW soundings south of G117A, usually when crossing side creeks. While 7′ MLW is adequate for most cruisers, the channel is very narrow there and appears to shoal rapidly off centerline. Due to our draft, I time this with some tide and take it slow, sticking to the “magic-enta” line.
