Unused thru hull

[dMAC]

I want to remove a couple of unwanted and unneeded features on my boat, namely a marine washing machine and a dishwasher (I like to cruise but am not a live aboard ). Besides just closing down the thru hull valve should I also leave a small bit of the hose on it that has some type of plug at the end of it or is there a better sure fire way to do this (short of fiberglassing over the plug and permanently getting rid of the thru hull)?

Thanks for any advice.

Replace the hose barbed fitting with a pipe plug.
