Shortest Slalom Course Ski Lake? Who has skies there?
RAIBERT RJ
some good stories about how short your lake is. (Any boats get beached?)
I need some help. Our club, Ski Club of Indianapolis, is looking at
leasing a SHORT lake. This lake would require a turn start and some good
drivers.
*** How short can a lake be and still be feasible? ***
The lake we are considering is a rectangle with the respective diagonals
measuring 1550 ft and 1700 ft.
Thanks in advance for your input.

Your proposed lake is 2300 feet on the diagonal (doesn't leave much room
to turn when you get into those corners, though :-) ). But even if you
go straight down your lake the long way, you could have 425 feet on each
end of the course. I'm speaking from no experience whatsoever, but that
sounds like plenty of room to me. Go down the diagonal and you get 725
feet on each end.
Whoa a minute. I just reread what you wrote. You said the lake was a
_rectangle_ with _diagonals_ of 1550 and 1700. Did you mean a quadrangle
rather than a rectangle, or did you mean sides rather than diagonals?

me but you gain about 300' on the starts by using this method. Drop me a note if you
want the diaram for this.

BTW, I found this using the Deja News archive service for
newsgroups and querying "slalom & course & distance". Totally
cool. Here's the URL.

BTW, you can also use this to find all of the articles written
by a particular author. This can be used to form a 'profile'
of what kind of language a person uses, and what kinds of
biases a person shows. I won't be embarrassed by anything a
person will find. Will you. Remember, we are what we write

The proposed lake is an "approximate" rectangle with the shorter diagonal
measuring 1550 ft. and the longer diagonal measuring 1700ft.
We generally drop at both ends, even on a course long enough to circle.
With a lake this short we would definetely have to drop at both ends and
whip the skier out to the left in a turn start(hold on tight!).

wrong) that indicated the minimum recommended distance for a
slalom course, and I think he had lengths for trick, jump as
well. Some one help me here.
What I remember that will be of interest to you is that he
talked about putting up an eight bouy course so that you could
have the course 'off center' in either direction. The skier
ignores the first two sets of balls while the boat is still
speeding up and skis the remaining six sets. Obviously this
improves the set up at the expense of the exit, so watch the
beach.
Good Luck, Chip

Thanks for the credit, Chip, but it wasn't me. I'd guess TJ or John Cox.

of the shore. Short line crashes can be hazardous out at the bouys. We
have only had three people hit the shore. One had six stitches, the
other two went in feet first, and dinged their skis up a little. Rule of
thumb, do not ski late and fast in narrow conditions! We also have to
drop at each end, this is not much of a problem, it gives you time to
coach the skier, and think about what your doing. Quality not quanity is
what counts anyway with comp water skiing. I don't know the #
measurments, but I do know set up to gates can be a little different,
short and rushed, but you learn how to compensate.

The Dimensions of the Perfect Ski Lake
(As defined by WaterSki Magazine, in articles by Phil Yastrow, published
in June & July issues, 1991)
*********************************************
Slalom
Lengths : 1600 ft min, 2150 ft Nom, 2400 ft Luxury
Widths : 175 ft min/lux, 225 ft Nom.
Jump
Lengths : 2000 ft min, 2150 ft Nom, 2400 ft Luxury
Widths : 275 ft min/lux, 300 ft Nom.
Trick
Lengths : 1200 ft min, 1600 ft Nom, 2000 ft Luxury
Widths : 100 ft min/lux, 150 ft Nom.
Barefooting
Lengths : 1600 ft min, 2150 ft Nom, 2600 ft Luxury
Widths : 100 ft min/lux, 150 ft Nom.
The "Min" dimension means the minimum acceptable safety and convenience
levels can be met. "Nom" means nominal - a comfortable dimension that
requires fewer special driving techniques for good water. The "lux"
dimension is a luxury - not completely necessary, but if you can get away
with it, you will be happy every pass down the lake.

With the help of the local MasterCraft dealer, Skiers Edge, they called
the Pro Tour directors about the lake used for the Pro Tour Stop in
Indianapolis, The Precedent. That lake has a maximum length of 1640 feet
with the jump off towards one end so that there is enough setup time.
However, this make for an interesting time of riding the jump out.
The lake in consideration by the Ski Klub of Indianapolis(SKI) is 1700 ft.
Therefore, we are going to pursue the lake lease for 1996!
Thanks for the valuable information in the previous posts and thanks to
Mark and Steve at Skier's Edge.
