Likewise, a vessel could be engaged in fishing per Rule 3, even if not displaying the dayshapes per Rule 26.
Bottom line is that the definition in Rule 3 should be clarified. One man's defintion of "restricted manueverability" may not be another's. Rule 26 is pretty clear with respect to trolling lines, but it is not clear with respec to those outrigger boards, or whatever they are called.
