Another dealer/manufacturer issue

A buddy of mine has a 2006 wakeboat (I'll leave the brand out but it's a major player in the wakeboat business) that had a floor issue. Recently a "soft spot" developed on the floor and my friend did not drop anything to cause or damage the floor, nor was there any abusive kids/people horseplaying in the boat. He keeps his boat stored covered/indoors as well. He asked me about the floor issue and if I thought the dealer/manufacturer would cover that in the "life time" hull warranty. Turns out they honored the actual floor repair BUT they will not cover replacing the carpet they cut up to get to the damage. They said they would patch the area with a piece of the old carpet and try to minimize the seam or patch it with new carpet (even worse). My friend said that he did not like the idea and basically said his boat needed to be returned to him in the same or better condition after the manufacturer admitted there was a defect in the boat floor. After more phone calls, even to the manufacturer, they gave him two options...patch it or they will give him a roll of carpet and he can pay someone to do it. We're trying to figure what you guy's opinion on this is. My friend has done quite a bit of upholstery work before and is man of principle. He said that trying to patch/blend the carpet will take nearly as much time to lay down the new carpet.

1. Should the dealer/manufacturer repair the carpet entirely after admitting the floor was defective.

2. Do you think he should be happy with the floor repair and pay for the carpet to be installed or do it himself
