My Hunter 27 was put into the water 3 weeks ago and the Marina did a beautiful job installing a new Harken furling system. The Marina provided me with a written estimate which included parts and labor. The price for the parts were nicely discounted but the total cost was still about $3400. I picked up the new sail for the furling system at the local Doyle sailmaker and was going to install the sail myself to save on the cost of labor if there was an additional charge by the Marina. I spoke to the manager of the Marina and asked him if there would be a charge for installing the new sail or would the labor cost be covered as part of the installation of the new furling system. The Marina manager told me there would be no charge and they want to install it to make sure everything fits and is operating correctly. Well you know what comes next. I received a bill for $55 labor and $20 miscelaneous materials for the installation of the new sail. I questioned the Manager regarding our previous conversation about no additional charge and his answer was "we did do the work". I have been at this marina for 3 years and havehad a good relationship with the manager and other employees, but I still feel that I have been taken advantage of. I am used to doing all of my own work which, as you well know, saves a bundle of money.I would appreciate some advice on how to handle this situation. Do I suck it up and pay it or argue the situation?
