You have the same hull as the 1995-1997 ProStar 190, That hull in 98 was renamed (SportStar 19, ProStar 195, and X-5)with the introduction of the Deathstar.

Ok, I am trying to keep up here. You all are saying there was a hull change in 98 or 99 that made the wake worse as well as an increase of 150lbs? Are there other Specifics I need to know other than get an early 90's or stick with a 97-01 Ski Nautique *I am looking for a ski specific tournament type wake* Thanks!

Long story short, the 98-2000 ps190 was known to track terribly , have a hard wake and and sometimes even chine lock ( did so on the AWSA test, thus nicknamed the Deathstar). MC try to fix some of these issues with a winged rudder, a fourth tracking fin and bolt on rails. Honestly the boat isnt that bad, but there are better. A 97-2001 CC will be a better tow boat. Or get a 91-97ps 190.

"Chine Locking or Hard Chine, is when the boat either falls to one side or is pushed to one side by a swell (I'm not reffering to turning to the side but hard listing.) Once it is pushed far enough, one of the longitudinals that run on both sides of the keel take over as the keel. This causes the boat to ride listed over constantly until the power is taken off and the boat settles back into position. Chine lock is dangerous not only because the boat is listing hard to one side and the freeboard on that side becomes extremely minimal, but because the boat can turn hard to the side it is leaning toward ejecting people or rolling the boat. The best way to counter this chine lock is to reduce speed. As a Surfman in the U.S. Coast Guard I encounter this all the time during heavy weather operations. There are other methods to release a chine but dropping the speed is the safest. If you are paying particular attention to the feel of the boat you can tell when the boat is about to chine. Turning the wheel is an effective way to avoid a hard chine or chine lock, because in most instances turning slows the boat just enough to allow the boat to settle again." Seems like a good definition to me, but that don't mean much.. |

You basically loose steering control. All boats are suseptable to this, however the "Deathstar " did it during the AWSA test and ended up on shore. Not good! I've seen happen on and 02 190 as well.

"I will say that a small boat chine lock is most likely encountered in a moderate to hard turn. Some boats will only chine lock turning in one direction (right vs. left). This has to do with the way the boat rides in the corner of a turn, and the rotation of the prop. The skegs or chines on the bottom our hulls are intended to improve directional stability. This is great when they are pointed down, but during a turn they obviously rise to the outside of the turn. They are also likely pointed nose high at this point. Typically, the boat is nose high due to passengers in the rear, or heavy weighting aft. Now instead of acting like a rudder, they begin to take on behavior of a wing. These forces actually add to the rolling of the hull to the inside of the turn, yet are pulling the hull to the outside of the turn. It's at this point that the boat will almost squat as if to say we turn no more, we're in the rockin' chair right here. I would say chine locks are more pronounced on a V-hull boat. The V-hull now acts more like a flat bottom boat. In a right turn, the rudder is turning the boat right, but the chines are like a wing holding the center line of the boat up and seemingly left, and the right side of the V-hull is nearly flat to the water. Now the boat is locked up, not turning right and not turning left. When this happens, a boat can be looking at a shore that previously was far away, but is now dead ahead! There is one sure fire way to get of this condition, and that is to reduce power or come to a full stop if required to avoid an impact. I personally have had to throw the boat into full reverse! In some boats, you can add more turn to the wheel, and this alone will be enough to overcome the lifting force on the chines and swings the back around through the turn." Again, might be decent info for some to keep in the back of their minds...jump in if someone can add further quantifying or qualifying info....I realize that all the above, etc. might not be germane to 1998~2000 PS190's, but that Deathstar nickname hit me pretty hard....knock on wood. |

I've heard about it on the early Evo hulls too. And that MC didn't believe it until one higher up officer of the company ran one aground. It was explained to me that the early evos were a symmetrical hull design which can make it prone to chine lock. And that the hulls were slightly redesigned to make them asymmetrical.
