That is plenty of boat to take offshore we run 20-30 miles in a 19 foot Cape Horn and a buddy of mine runs 50-60 miles in a 21 foot Cape Horn. Just get used to the boat and venture a little farther each time you go out till you feel comfortable. I dont how many gallons of fuel the boat holds but use the 1/3 rule a 1/3 out a 1/3 return and 1/3 reserve you should be fine. I would defintley get a VHF radio and all required coast guard equipment.
