I have to go with cpn Tom. 20 degrees isn't considered to be cold around here. (Northern Wisconsin) Not sure about salt water but fresh water turns mushy before it becomes solid. A couple days of 20 degrees really won't hurt the engines. Open all the water taps on the domestic side to relieve pressure and if you have any drains on the engine open them (seawater side). Those magnetic block heaters will keep the engine warm enough to prevent damage or a couple space heaters.
Around here we use the -50 RV antifreeze a lot. A jug left outside at -30 is mushy but not powerful enough to do any damage. I don't think you have anything to worry about at 20 degrees, even on the hard.
