Knobber, how big is your pond?
Can you do it from shore with ropes and two people? (Or you plus wife on ATV, etc.?)
The whole pond might be too heavy of a load to drag onto shore, so maybe make your "seine" only a 1/2-pond-width long?
P.S. I wonder how much of those mats grew last year and stayed on the bottom before your P-binder started to effect your water chemistry. Are you going to try it one more year to check the longer term results?
