Lovely to see your wife skiing. In addition to the above comments, I would get her a bigger ski to start off with, that would make the slow speeds easier as the ski would be on the water and not in the water (as your vid shows she's sinking round the buoys and a lot of energy is needed to get the ski on the plane again). Alternatively you can move her bindings as far forward as possible so that more of the ski's area is in contact with the water. Obviously as the speed goes up, and she's more stacked, you would get to the point where you would have to move the bindings back. J.J.

1983 Gwagon, I only tow about 400m from the lockers to the slipway :)

You can take pictures like this one Horton

LINK This one?

I shall be admiring for afar here in South Africa Shipping and Import duties just makes it too expensive :'( JJ

This is video of Aidan (my son) using Double OB4/MOB system with Radar Vapor Double bindings. He's now using OB4/MOB Vapor front with a RTP, I'm on OB4/MOB double boots. I've only once had the rear releasing and the front not, and that was just because there was not enough stress to release the front boot, so no injuries.

I don't post much but here one vid.

My whole family uses OB4, for me it's all about safety (not having huge medical bills) and having the confidence to push the limits. I have uploaded this before. Regards, JJ

Slow the boat speed down and shorten?

Thanks for the feedback.

@MISkier, would it be correct to say that if I'm wide and early at the buoy, I would get the same pull / feel as when I'm narrow and late (especially in setting C as it reacts the earliest)?

@MISkier, yes that virtual timing's pull between buoys get determined by settings A1-C3, if you have a longer rope the boat will pull you at a different place / position in the course than a short rope. The boat has to pass the 6 buoys in a certain time, so it must pull the skier 6 times at 6 GPS points (different GPS points for A, B & C) in the course to catch up. Do the experiment, map the course 4m early at entry as well as exit, this will give you a 8m variance in the course in the 2 directions, effectively changing your rope length by 8m in the two directions as well as GPS points for settings A, B & C. If you feel a difference in the two directions, then my theory of ZO reacting to GPS points, to catch up your pull, are correct

This is what I experienced with my boat, the ZO course calibration was out by more than a boat length, this would cause the ZO to beep before the boat passed the buoys in one direction and after the buoys in the other. I had three skiers that regularly ski behind my boat complain that the boat felt different going through the course, especially in the one direction (pulling them too early). So my thinking was, ZO does wait for pull on the boat, but then reacts to that pull according to the GPS position of the boat in relation to the buoys. I remapped the course and they were happy.

Let me elaborate on the above question. When you map a course with ZO, it maps the course in relation to the boat position and not the skier's position. So this is why I'm asking this question. The distance between buoys being 41m means that somewhere in the 1st 13.667m setting C pulls, the 2nd 13.667m, B and the last 13.667m setting A Skiing at 15off the skier is 18.25m from the boat, and at 43off, 9.75m from the boat which means that the A, B & C settings pulls the 15off skier 8.5m earlier in the course than the 43off skier, that's more than 1/2 way into the previous setting, meaning that settings A becomes B, B becomes C and C becomes A at 15off if you compare it to 43off. As you shorten the rope you get pulled that shortened distance later in the course. ZO would be more consistent (accurate) if the skiers rope length was also entered, obviously this would have to be done after every pass as the skiers shortens. @Horton please move the post to the correct Category if needed Regards, JJ

+1 on the Vapors
