At displacement speeds the trim tabs are left fully retracted. When you start
to go from displacement to planing speeds, the trim tabs are depressed (bow
down). One the boat is fully on a plane, slowly retract the tabs, keeping the
boat riding level. If the power is marginal to keep the boat on a plane, you
may have to have some tab down to stay on the plane. Also if the boat begins
to porpoise or to contra act wind, you may deploy tabs.
If you are in a following sea, be very careful of running with tabs down. You
could depress the bow, causing "bow steering" or a broach!
