Brett,

That was also a worry of mine, as was getting fishing lines hung up. I decided free-floating single PVC pipes would take care of both problems. I cut the PVC pipes around 2.5 feet long. I plugged 1 end with clay ballast, causing them to sink to the bottom yet stand fairly upright. I placed them in "groves" of 20 or so. I think it would take a very freaky accident for them to hurt anyone. I think 99 times out of 100, they will just move out of the way when someone runs into them. I can also tell you they attract LMB.
