I have been boating on a river with fairly strong current and the dock is very high and made of concrete (there are rubber bumper guards lining the dock). Even when I think am right on, the last second pull back of the throttle causes a sideways shift resulting in a direct hit on either one front corner or one back corner. Realizing it will look stupid, is anyone familiar with corner guards that can be permanently mounted to save my gating. Any help would be greatly appreciated.
