It’s no surprise that a lot of new boaters may not know much
about boat trimming or what it means. It’s understandable since this is not
necessarily the most basic stuff, they need to know on boating 101. However,
knowing what it means to trim a boat and how to trim it properly will improve the
boat’s performance and fuel economy.
So, what is boat trim? It doesn’t mean cutting away some
parts of a boat literally but it means the running angle of the boat as it
makes its way in the water whenever a boater adjusts the trim by raising or
lowering the front of the boat.
The next thing to know now is how to trim a boat in the
water. The process is simple and if you already are comfortable enough to
operate your boat all by yourself, you should definitely do some trimming. It
helps your boat glide more smoothly and faster on the water’s surface. Here are
some tips to help you do it:
Distribute
weight evenly
Before you leave the dock, check that the weight
of the boat is distributed evenly so it sits evenly in the water. Adjust
all boat
accessories, equipment, and gear you have onboard so no part of the
boat has a bigger and heavier load sitting on compared to the other areas
of the boat. Even though you can use power trim and trim tabs to
compensate for uneven weight, it’s ideal to begin by distributing weight
onboard as evenly as possible.
Use
your power trim and trim tabs simultaneously
Remember to use the
power trim to adjust the prop path that is parallel to the water flow. Use
trim tabs to trim the hull of the boat both up and down and from side-to-side
motions. When you use the two of them together, you maximize your boat’s
performance.
Monitor
the speed and propeller action as you trim
As you begin to trim
up, pay attention to your boat’s speed, revolutions per minute (RPMs), and
propeller ventilation as these three are key to knowing when your boat is
properly trimmed and running efficiently. Trimming up will eventually
trigger a slight drop in speed and a sharp rise in RPMs and propeller
ventilation. If you’ve trimmed up too far, begin trimming down in small
increments to reach your maximum speed and consistent RPMs to balance for
a proper trim.
Use
your trim as a turning tool
When you enter a turn, begin
trimming down remember that the more you trim down, the more you can accelerate
through a turn. When you’re in the sharpest part of the turn, you should
have the maximum amount of down trim, based on the turn speed and radius.
As the boat slows, add some more throttle. As you begin straightening the
wheel to come out of the turn, begin to trim up.
Your
bow spray and stern wake can help you trim
If you’re steering
your boat from a bridge, you have the opportunity to observe other
characteristics related to spray and wake that can help you find your
boat’s ideal trim. If you see more spray toward the stern of the boat and
a larger wake, the boat’s trim can be better, unless, of course, you’ve
got a boat full of water skiers and wakeboarders. When your boat is
reaching its proper trim, you’ll notice the bow spray is farther forward,
the wake is smaller and the rooster tail is also smaller and farther
behind your boat.
Do
not over-trim
Make sure you do not over-trim, especially at high
speeds. Extreme changes to the angle of the bow on the move, combined with
sea conditions, can cause the boat to veer off. If you have trim tabs,
remember that even though the trim tabs are adjustable, you should not
move one trim tab significantly further down than the other one, as it may
cause the boat to lean suddenly to one side. It could capsize your boat.
Start
with trim down
When you’re taking off from displacement speeds,
most boats work best with the engine and bow trimmed down since this helps
the boat rise quickly onto the plane. However, once your boat is in its plane
position, it’s important to adjust the trim based on the sea conditions.
Keep
trim adjustments small
To find that good spot for your boat’s
trim, it’s important to make sure you adjust your trim tabs using short,
half-second bursts followed by a pause to let the boat react before moving
on to make another adjustment. How long it takes each boat to respond is
different, as the size of your trim tabs and your boat’s speed affect the
timing.
Be
aware of trim’s effect on your wake
Trim settings will change
the size of your wake. You want to trim down to minimize your wake in a
slow or no-wake zone. On the other hand, if you’re looking for a better
wake for waterskiing or wakeboarding, trim up while adding speed, and you
might see a rooster tail.
Occasionally
check your trim tabs
As with any part of a boat, trim tabs can
have loose or corroded wires over time. Since they can have such an impact
on the trim of your Quintrex boat,
it’s important to inspect them visually to ensure they don’t need repair.
Malfunctions or failures of trim tabs can be dangerous.
