I have a whale tail on my fish and ski and it does seem to help get on plane on slow speeds. I do think it slows broat down too. I was thinking about jack plate but could not find anyone using on fish and ski. I am trying to get better results when pulling tubers and people skiing. Plus my boat seems to porpoise and trying to fix that problem. The whale tale helps with that too but looking better over all boat control option.i have a charger fish and ski that is 20 long with 200hp
