You can consider the 196/200 Osprey to be like a bay boat. You can certainly take it offshore on the right day, especially if you don’t have far to run.
As far as outfitting it for offshore fishing, what kind of fishing do you want to do, trolling, bottom fishing, live bait? You can always add accessories like outriggers, downriggers, rod holders, or larger baitwell to customize the boat for your style of fishing.
Trim tabs are a good idea, so you can keep the bow down and plane at lower speeds. Make sure you have working safety gear, VHF radio, PLB, full coast guard kit all in good working order.
