Before you go getting lawyers you should consider how much your boat is worth$$, how long you want to deal with this frustration, and how much the lawyer is going to cost??? Just because you want to settle this issue does not mean the powerboat guy does. The longer he can drag this out the more likely you will give up due to frustration with the legal system. It simetimes can take 5 years to get to court only to find out the other side has new representation and require a continuance to become familar with the case...depending on whether the judge will or will not grant it.
