Site hazards: Gulf visibility here is hit-or-miss, ranging from very poor to very good even within the better late-spring season. The reef is a listed fishing destination on local GPS coordinate guides, so expect fishing boats overhead. Relief is low (max ~1.7 m) and the patches are scattered across a 0.27 x 0.46 mi area, so underwater navigation between clusters is easy to misjudge.
