This wouldn't need to be a Ranger specific ability but instead a survival skill check if people are hunting in an area with water, they should get a boost to attack and defense based on swimming skill or lack thereof. I am not suggesting anything drastic , but perhaps a 10 percent addition subtraction to hit /damage and avoid damage with defenses if your swimming ranks are substantially low or high for the critter or area.
I suggest this with swimming as my tenth survival so , I am not just promoting my own interests here. I just feel many skills should have uses beyond merely circling or getting from point a to point b.
Also depending on our swimming and climbing if applicable we should be able to use hunt in areas with these obstacles, please?
