I know there is a situation wherein you are allowed to make a tactical rounding, but always get them confused. I know someone said "no obligations" allows you to do that.. can you be more specific and use it in an example? Anyone got a pic of when you are at the mark with another boat and are allowed to make a tactical rounding?
Only time you can make a tactical rounding is when you have no other give way boats.
As soon as there is a boat outside you that is give-way, you must make a seaman like rounding (so no out wide and in tight). If you are give way boat, you only have to allow the inside boat room to get around the mark.
