Since the .Org is the oracle of all knowledge, humanly possible or otherwise, I thought I'd ask the below.

At the moment, as it's early days, I'm going to keep it as generic as possible.
What I'm interested in, is lien's & subsequent sales.
From my understanding, for example with mooring fees going unpaid, the Marina can place a lien on the vessel (prohibiting movement until the debt is settled). Whilst the lien is in force, the Marina can continue to charge a nominal storage fee, but all costs must be specified on the lien otherwise it's not enforcable. A copy of the lien must be sent to the owner of the vessel, or at least sufficient evidence be available showing that a search for the owner was unsucessful.
Once the debt reaches the value of the vessel, the Marina can put a "notice of intent to sell" on the vessel. Again, this notice must be served to the owner (if located).
At that point, the Marina are quite within their rights to sell the vessel to recover their costs incurred (unpaid fees, plus other associated costs).
Have I been informed correctly? Can anyone expand on any complications to the above (other than mortgage companies etc being involved as stakeholders)?
Much obliged.
