Welcome Hooked! There is no blanket answer on the capability question. A lot of factors are involved. When it gets too rough its not fun on any boat. It sounds like you are not new to offshore, just the V20. The main restriction is going to be fuel and weather conditions. As you know certain winds are more favorable for a specific area. It may be dead calm within 5 miles of the beach and down right nasty out past that.
Watching the weather forecast and knowing your fuel burn rate is key. For example I get around 2 - 2.5 mpg with my setup. I've done a few 40 mile trips one way in less than ideal conditions, trolled 5 hours and came back with around 10 gallons to spare in my 60 gallon tank. Cut a little too close IMO!
All things considered I would not want to be 10 - 20 - or 30 + miles away in a building head sea on the return. One thing about the V's is when the waves stack up close you can and will start to take them over the bow. In this type of scenario it makes for a long slow ride +/- 10 mph.
My conclusion is the smaller the boat the more diligent you have to be in watching the weather and conditions. And always consider that things could change in a hurry - just like in any size boat.
My .02 - probably nothing you didn't know already! Again welcome!
