Here's a copy of the indemnification paragraph from my dock contract:
INDEMNIFICATION. Lessee shall fully and forever indemnify, hold harmless, and defend Lessor from and against all claims, demands, causes of action, liabilities, damages, and costs (including reasonable attorneys’ fees) in connection with or arising out of any action or omission by Lessee – or by any of Lessee’s invitees, agents, contractors, or subcontractors – in any way related to Lessee’s Vessel or the marina. Lessee’s indemnity, hold harmless, and defense obligations shall apply even in instances in which Lessor or any third party is negligent; accordingly, Lessee agrees to indemnify, hold harmless, and defend Lessor even against the consequences of Lessor’s own negligence. However, Lessee shall have no obligation to indemnify, hold harmless, or defend Lessor in instances in which Lessor is solely negligent.
My reading says that the marina cannot be held responsible unless it is solely responsible. For example, if I don't tie my boat correctly and a storm arises and the boat is damaged, I can't hold the marina responsible for any damage because they didn't secure it or if they tried to secure the boat, it was unsuccessful, because if the negligence is traced back, it starts with my poor dock line selection. However, if they haul the boat and drop it, then they are on the hook because the negligence is solely theirs.
BTW, my marina is owned by a Philadelphia Lawyer. He's a nice guy who runs a nice marina.
