Special Attention 
On the X2, X10, X30, X46, and XSTAR models, GEN2 WSDs are 
limited to seventy-five percent (75%) maximum extension when the  
boat speed exceeds twenty miles per hour (20 mph) or thirty-two 
kilometers per hour (32 km/h).
On the X20 and X23 models, GEN2 WSDs are limited to seventy-five 
percent (75%) maximum extension when the boat speed exceeds 
twenty five miles per hour (25 mph) or forty kilometers per hour 
(40 km/h).
Maneuvering a boat with the WSDs extended requires 
practice to master. Initial times running with the surf tabs extended 
should be done at low speed with plenty of room. This is critical to 
learning how the WSDs affect control and maneuverability, espe-
cially when actuating WSDs with the attitude adjustment plate(s).
Electromechanical actuators provide an instant response. When 
making adjustments, use short momentary taps of the switch. 
BALLAST SYSTEMS
Models 
A triple hard tank ballast system is standard on all X-series and NXT 
series boats. These ballast tanks cannot be removed after the boat 
has been built due to tight tolerance to fit between the deck and the 
Hull. The GEN2 Surf System, explained immediately previously to 
this section has additional plug-in bags. The bags connect through 
quick-connect fittings located in the rear storage compartment. The 
ProStar ballast system is similar to the X-Series, but features  a single 
MTS. The NXT series has optional wake shaping devices and additional 
quick-connect bags when selected, but does not come with the GEN2 
software. 
Purpose 
Ballast systems were specially designed for each model of 
MasterCraft boats to enhance enjoyment of boating. By creating 
deeper, more dynamic waves in the wake, boarding enthusiasts 
with skills ranging from beginners to professional boarders have 
discovered more enjoyable, even record-setting experiences. For 
simple outings and quicker reaction by the boat, ballast systems can 
be left empty. Filling ballast tanks, and optional bags, however, sets the 
stage for exciting and fun experiences.
