Not happy with my cover from National.
I went with a cover of a different material than my old SunBrella one.
First time towing with it on and it got 2 small rips on the back corners.
The reason it ripped was the reinforcement on the underside of the cover did not cover the entire aluminum plate on the corner of the boat.
My old custom cover(Sunbrella, 12 years old) was reinforced properly on the corners and never tore.
I sent pictures to National Boat covers about the small tears.
After many emails they said to bad.
This is a semi custom cover.
I will always get a custom cover from now on.
Twice the price.
Twice as nice.
