Hopefully someone can help locally...wont be down that way till December.
But the learning curve for twins is about 20 times easier than a single.
Both my young son and the sons of several of my friends wound up better boat handlers than their dads in just a few years of very part time boating....so maybe computer gaming is a good thing...
Twins are much more intuitive because now you have more of an advantage over the elements than a single without thruster.
My first time with twins (except ships 110 foot plus) was when the broker told me to take my last boat to the fuel dock about 5 miles away. It was still prepurchase and refueling was for the sea trial...he sent along a dockhand to make me feel better...when I asked the dockhand said he had never handled a boat so I was on my own.
Go slow and use the pointers of others...and my bet is you will be fine.
Like most things in life...watch the weather and don't bite off more than you can chew.
