I really enjoy ship sim and all of its new features. But I have to admitt there isn't much challenge. I would like to see a sim developed focusing on the most dangerous and challenging time for any ships officers. That would be River transits and docking. To keep it simple I would like to see a Harbor Pilot sim. This sim should include every daunting task these most experienced mariners face while guiding ships to and from there berth. I am a licensed mariner and know from experience the magnatude of competence it takes to navigate a large ship up a narrow channel with few points to pass and areas barely wide enough for one ship to transit. The St.Johns River in Jacksonville, Florida is a perfect example. This sim should also include the Panama Canal. Has anyone ever heard of Texas chicken? These are the challenges I would like to see in future sims.
