Indeed, that would have been exposed! It was quite windy all that week...Just inside past the old light in about 10 feet of water. Not a good choice but we were tired and "expecting" a quiet night. After all, we had just checked the NOAA forecast.
It would have been better to cross over to the Severn River.
The week before we ducked into Poquoson River which was nice and heading back on Wed of last week we used Horn Harbor. We had stayed at marina before and tho channel is narrow coming in, it's well marked and it's a great spot to duck in - assuming you can live in 7-8' water - as there's not much else between Rap/Piank and NFK.
I have the 'pay once lifetime' version of Windy app and I've tried all the FX models only to find them all a bit of a crapshoot. The bay is just too subject to thermal, microclimate, landmass, water depth effects. <sigh>
