You would be better off starting your own thread, due to the difference in topic especially. However, we can work with this... First of all, where do you have the game installed - in other words, which folder? Do you have any mods activated? Do you happen to know which version of the game you are using (ie: v1.3, v1.4, v1.5 etc)? Are the sea conditions really rough, like 15ms winds, and sea breaking over the fairweather? The constant reporting of depth happens when the boat is unstable, and I do remember and earlier version of the game having that issue, but I do not recall which one it was... been too long. But a mod issue can also do similar, especially if you activated a mod that is not compatible with your current game version, or if the Save folder is messed-up from some other issue...
