user: Im considering buying a boat?  How do I decide which boat meets my needs?

assistant: Things you should consider when making a boat buying decision.  How much space do you have to store the boat?  Will the boat be used in fresh or salt water?  Inboard motors are great for fresh water environments.  Outboard motors are often preferable for salt water applications. If you plan on using the boat for fishing, you need to decide if you will be fishing offshore or inshore.  Inshore fishing requires a smaller draft.  Draft is how much water a boat needs to float.  Offshore fishing boats have deeper drafts based on the hull.  Offshore boats can handle rougher water based on more aggressive hulls.  Offshore boats have steeper dead rise.  Dead rise is the angle of entry for the boat hull.  More aggressive dead-rise leas to a softer land in harsh water conditions.
