I'm looking to get a new cover made from National Boat Cover. I purchased their windstorm cover and it did not last any where near the 7 year warranty, less than half that only being used in the summer months.
I need a new cover made and would like to get a better, longer lasting fabric. Can anyone tell me the difference between their Sunbrella and Sunflair fabric? They are both rated at 10 years with the Sunflair a few bucks cheaper.

it is my understanding it is basically generic sunbrella like "tylenol" vs the store brand. Both work the same way. Considering the cost and use I'd go Sunbrella personally because they weigh the same (too much) so unless there was some other benefit it would have to be WAY cheaper

Wouldn’t cheap out on material..go sunbrella

Thanks Sunbrella it is!

I have the windstorm also....No where close to 7 years. Plus a hassle to do any warranty claim.

The first cover lasted 3 years (7 year rated cover). I called up the company and it is prorated. If my memory is correct they charged me 30%(?) additional to get a new cover. 2 years later the replacement cover is leaking water, can see light coming through all over (I apply water proofing once or twice a year) and starting to tear in 2 places. I call the company up and they say there is only one replacement, after numerous calls and requests to send pictures, which I did. So I paid 130% to get 5 years out of a 7 year cover that is used appropriately 5 months a year. I must say they did not give me a hard time for the first replacement. I just had to send pictures.
The cover fit pretty good for a semi-custom. I looked to get a new cover from other companies, but no one had my boat listed. I did not want to that a chance with a poor fitting cover. New sunbrella cover should be here in about a week. Hopefully it lasts longer than the other 2 as it was almost twice the cost. This cover has a 4 year 100% replacement than prorated after that.
I'll report back when the new cover arrives.
