Someone might want to explain the difference between a coral reefbreak and a granite
one... I think that is the confusion here...

I think you're right, LegendJim... typically we talk about "rock reefs" in New England, where waves and currents have arranged reef-like structures of material exposed and/or deposited from the last ice age. All the granite in New England is rock that sort of bubbled up through the crust as magma, then cooled and solidified. Glaciation then scraped a lot of the crust off, and bulldozed up material to form some of the coastal landforms in the area. Weathering broke up much of that material into boulders, cobbles, and clastics that are deposited along beaches and just offshore in "reefs."
Other than that, there are no true reefs north of Florida and the Bahamas. You can find coral from another time period, when the ocean here was shallower and warmer.... but that was a loooong time ago.
Here, in New Jersey, we don't have reefs. But we do have clam beds and shoals, and we have the Shrewsbury Rocks and Elberon Grounds, but they're hardly reefs. The theory is that these structures are the remnants of an ancient shoreline.

Also, not too far South from me is the Northern most Coquina reef structure in the Atlantic.
If you want to surf live reef and fire coral, you have to go tropical

"Live bottom" is rock, covered with living organisms... a reef only in the same sense as the "rock reefs" of New England. In subtropical and tropical waters it may even have coral, but it's not a coral reef.
What is the Coquina Reef? Is it built up from Coquina shells?

Coquina reef is comprised of many different kinds of shells cemented together with sand stone. It's called Coquina because they are most prevalent in Florida where they are mostly comprised of coquina shells. It's actually pretty interesting how it played into Ft. Fisher's (NC) development and how it was mined in the 20's to create a road bed ultimately leading to massive erosion taking out half the land at the fort and requiring millions to be spent on man made rock bulkheads to save the rest of the historic site. This area is now where the First and Second Cove are. They used to be much better breaks before the walls were re-done in the late 80's and early 90's. Now it's just uber crowded and fickle

Eroc... I get it now. In fact, I recall seeing a lot of that coquina rock in Florida. Isn't that the rock that makes up a lot of the rocky parts of the coastline in South Florida?
In terms of true "coral reefs"... I think biologists make a distinction between a thin veneer of coral growing over rock, and coral that grows layer upon layer over itself for thousands of years. The substrate would be limestone under a coral reef, because it's the remains of dead hard corals themselves. The substrate under a coral-covered rock reef can be any rock, and my guess is that in your area, the corals are mostly soft corals, with perhaps some stony corals mixed in. At least that would be my guess...

We have a very small rock reef in Southern NC. Only one in NC I believe. It never breaks well.
