The wonderful little V-20 with a single engine and 60 gal tank was not in my humble opinion designed to be a canyon runner but on clear calm days I've seen them as well as whalers and gradys of the same size 15 to 20 miles out but I prefer bigger boats with twins and extended fuel capabilities for long big water runs but thats just me.The older I get the more I realize how quickly the Ocean can turn from calm to deadly in a short period of time because I am retired and get out 4 days a week all year long . I truly love V-20's but 4 foot quartering seas mean a very long trip back in with following seas at inlets right on your tail plus freighters , tugs and other traffic. I've been caught out like that myself numerous times and its best to find a big sport fisherman or dive boat to suck up behind especially when running dangerous inlets like here in North Carolina.
