I would run the AF through the engine and the fresh water system and then push it out using compressed air. The shop vac might work, as well.
There is an easy way to run your engine on the hard - use a 5 gal bucket in the cockpit, fill it with AF, attach a hose extension to your intake and put it into the bucket, run engine until all AF is gone. I use 5 gal to be sure - you don't want the AF to be diluted and you have to push out all the water from the lift muffler. For the fresh water, I don't pour AF into the tank - it would smell, and you are encouraging the growth in it. Rather, empty the tank, purge the water from all hoses using the compressed air (shop vac??) and then disconnect the hose from the intake on the pump, attach a spare length of hose to it (I bought a spare connector that threads onto the pump), put that hose into a bucket of AF and run through all faucets until solid pink comes out. When done, again purge all remnants of the AF from the hoses using pressured air. An RV store would have a adapter that you can attach to your air compressor (<$10); amazon has them, as well (Camco 36153 or 36143). If you have a water heater, install the bypass, so that AF won't run through it. Make sure that you don't forget your bilge pump(s) (both automatic and manual), potentially a pump for the ice box and any other pump you might have. If you have a shower sump - AF should go there.

Alcohol-based antifreeze is hard on rubber parts and seals. I used to use plumbing antifreeze (rated for potable water systems) in the onboard water supply system but found it difficult to eliminate the smell/taste afterwards. Now when I do it, I use a shop vac to suck the lines dry and run the water pump into the vac as well.
