Submerged Groin and Piles

I was recently studying the area we live on a nautical map and noticed the terms “Subm piles” and “Subm Groin”. I had to wonder…… because I am easily amused, the fact that the piles were south of the groin on this map of Freshwater Cove brought a giggle forward.

I concluded that “subm” must indicate submerged (I am not without some insight) and I had an idea what piles were in nautical terminology. I asked around a bit about “groin” without success. So, I googled it…….

According to the National Park Service, groins are used to maintain beaches and limit “longhsore sediment transport” (erosion?). And now we all know. It’s your “News You Can Use” segment of the blog…….
