I'm not sure how common this is, but it's worth checking before starting up the genset at 7 knots.

This is wrong. Water is incredible heavy. You would have to be going very fast to generate enough velocity pressure to lift the water up and over the anti-siphon break. Usually this break is 18"+ above sea level.
If there was any risk of this happening the tow boat captain would require you to close your engine seacock before he started towing you.
