can:.
a.. Compensate.for.wind.and.load.listing..
(level.the.boat.side.to.side).
b.. Induce.faster.planing.and.help.achieve..
optimum.running.angle.(see.Section.E-7.-.

The.proper.use.of.electric/hydraulic.trim.tabs.requires.
a.basic.understanding.of.trim.tab.operation.and.some.
practice.in.calm.water..Be.sure.to.read.the.manufac-
