And if surface waves are reduced, they can grow to a shallower depth without being eroded which may prevent any form of water craft passing it. | |

| Jun 12, 2017 at 2:01 | comment | added | Mark | Any barrier reef has a deep-water connection to the ocean -- tidal flows will prevent an unbroken ring from forming, or will quickly erode it open if it does form. Any captain worth his salt, upon approaching such a reef, would have someone up in the mast looking for the passage and someone with a lead-line in the bow taking soundings for it. A reef is tricky but not impassible to 17th century ships. | |
