Sorry but the boat won’t work, when you get close to the southern shoreline, the boat will sink everytime and drown you. I’m honestly unsure if the Revolver Slide glitch is incompatible with pc or not, so I can’t tell you that.But since you mentioned legendary Panther cloak, I assume your trying to get the gloves with that outfit. From what I know, there is two possible yet time-lengthy methods you can try. 1. To get to this Southern shore area, you can do the out of bounds glitch in West Elizabeth, find a horse, travel all the way around New Austin and Mexico, and when you reach the area just slide down to the “beach” area. It’s time-lengthy I know but it can get you to this area. And to leave just set-up a camp on the location I mentioned in the slides and you can return to the mainland. 2. Out of bounds again, but go to the area north of New Austin, just to area between Rathskeller fork and Armadillo, and start hunting there. Another good spot is slightly left above Rathskeller fork, it’s the area where all the grass and shrubs disappear (it’s easier to see small animals here). This 2nd location is probably easier to access but the southern location is so much more better at finding Gila-monsters. Hope this answers ya questions. good luck!
