Any paint can be removed with a solvent, that's what solvent does. So that's not a particularly good way to identify the type of paint you have. If the boat was trailered in the past, it likely has an ablative, as ablatives are able to withstand extended periods exposed to air, unlike other anti foulings.

Regardless, assuming it is not something exotic and assuming you don't intend to paint over it with something exotic, you can paint over it. Ablatives can go over ablatives or epoxies and conversely, epoxies can go over epoxies or ablatives. Generally just sand and paint. Here is the West Marine Paint Compatibility Chart for reference:
