If you have current you will probably need a current control system to keep the buoy arms relatively straight against the current. This can be as simple as setting an anchor up current from the arms on each side and running a non float type rope (3 strand nylon works well) from arm to arm to stabilize them against the current flow. Kind of a PITA with a portable but doable. In a lake or basically calm water it's not an issue, in current the current pushing against the arms sweeps them down course and out of alignment. If you're in more than 3 mph current it's probably more hassle to do than it's worth but thats your call.

If you need more info or have specific questions feel free to e-mail me at info at ez-slalom.com (obviously replace the "at" with a @).
