Have you considered a mesh apron that would go in front of you? Similar to some float tube designs. Make sure that it would be a very easy break away in case you need to escape quickly. Quick snap attachements with a little mono break leader on your side?
If you are casting in skinny water away from your yak, a traditional FF will have limited use. It would be usefull for recon of the bottom prior to fishing.
Post up your rig and your trips, interested in getting back to throwing flies.
