when you say "all the way down" I assume that means in the bow down position. Minimal tab means the tabs in the bow up position? Higher tabs also means bow up? This winter it has definately been a bigger swell so I have had some bigger following seas. How big a swell should I be concerned? I have had a few experiences with a quick lurch to one side - and i definately did not like it! I think I had by bow dug too deeply down. the ride seems much better with the bow up.

Does the trim of the moter make any difference?

Finally by efficency i assume you mean fuel. When offshore for tuna that definately makes a big difference. When shooting out to la Jolla I'd rather burn a few extra gallons for the time savings, but is there anything else I should be aware of on efficency?
