Probably not. Get reaaaaally seasick. Tried for years and miss wreck diving but hours of vomiting and being the guy no one wants to sit next to just sucked. Blackthorn was more like a big pile of steel but the Sheridan is awesome!! Really do miss that dive. Had 1 of my most memorable dives on the Sheridan. 125 plus tip and fills is a little pricey for me. For 3$ plus fills we hit a WMA and dive springs/sinks/caves. Tip money goes to gas. Dive safe and take lots of pics to post here and make me envious lol. Was just wondering why u needed the nitrox cert? Did many dives there and never used nitrox.
