Trim Tabs (Auto-Glide) - Regal 53 SC Owner's Manual

TRIM TABS-AUTO-GLIDE™ SYSTEM
Overview
Auto-Glide trim tabs are installed on the lower hull outside
transom area. They measure 24" wide by 16" deep. Water
is defl ected and redirected as the trim tabs are raised and
lowered from the dash switches. This change in water
fl ow creates upper pressure under the tabs, and raises the
stern. When the stern rises, the bow is lowered. Lowering
the port tab will cause the port stern to rise, making the
starboard bow lower. Lowering the starboard tab will cause
the starboard stern to rise, making the port bow lower.
Using trim tabs will compensate for uneven weight
distribution, listing, water conditions, wind velocity and
other factors that cause ineffi cient operation.
The Auto Glide™ boat control system option is the fi rst
fully automatic trim tab system available to yacht owners.
These trim tabs can be used in an automatic or manual
mode.
The system uses unsurpassed technology to monitor
boat speed and position, and when in the auto mode
adjusts the trim tabs position to accommodate any of the
above boating conditions to provide a smoother, more
comfortable ride.
This allows the captain to run his yacht the way it was
designed to perform resulting in fuel savings and safety-
improved visibility, hole shot mode and running angle.
The trim tab electronics system is compatible with the
CANBUS (Controller Area Network) network used on
marine engines. The tab electronics are connected into the
yacht's NMEA 2000 plug and play communication system.

TRIM TAB TRANSOM OVERVIEW
Your Regal yacht reaches a planing position at a designated
speed determined by bottom design, weight distribution,
water conditions, and on board equipment. As the throttle
is advanced the stern squats and the bow rises initially. The
trim tabs allow your boat to plane at a slower speed than
natural conditions allow.
As the boat breaks over the bow high attitude the boat
speed accelerates and visibility increases.
If the boat is over trimmed, it will plow the bow and the
boat will lose maneuverability. The Auto Glide system can
automatically compensate for stern drive over trimming.
This will produce a drier and more comfortable ride.
When trimmed or in the bow down position, the bow
spray is farther forward, the wake is smaller, and positioned
further behind the vessel. Also, when trimmed you will
notice that the tachometers show an increase in rpm's.
Your vessel can use the trim tabs to rectify a list. The trim
tabs adjust the boat's attitude in the direction the helm.
Porpoising is a running condition where the bow "bounces"
up and down similar to a porpoise motion. With the Auto
Glide system porpoising will recede and the vessel speed
should increase.
