18. No invisible boats. (Transparent boats must not be less than 50% transparent) Hey there all, I just realized that most moderators may have a bit of a problem enforcing this rule in the future. Here's the problem. I don't know what 50% transparency looks like on all of the props. I don't think there's any way of checking. I could be lied to by players because I have no way of checking. My question is, should the moderators and/or players use their own judgment as to whether or not it is breaking a rule? Or is there a way of checking for sure, and if not, could we perhaps have a method for doing this?
