If that works, it should be practical for a monohull with fin keel also (my centerboard is equivalent to a fin). If that doesn't work, I'll rig a snatch block on each side, from the aft end of the floats where the cross-beams attach. I'd be very surprised if that doesn't work well enough to let me sail to where I could anchor in relatively sheltered waters. Then there is the question of how much drag it needs.... I'm thinking I'd like to start with a single 100' looped warp to see if that's enough drag.
