Cost wise, anchors are less than a portable, but a WHOLE lot more work. I've currently got a rope course on the lake I ski and will use it as a template for an anchored course. I've measured the depth at every buoy and have buoy lines cut to appropriate length and ready to roll (using the fingertrap method with sub buoy). The depth at most buoys is 18' - 20'. Anchors are ready. Albritton and Mattox are in charge of setting anchors (much appreciated!). Waiting on everyone's schedule to line up, may not happen before the cold sets in. Otherwise, we'll get it this coming spring.
The anchors are a little intimidating. 200+ lbs of dead weight is no joke.
