Boat Cover Help

[Kent]

Kent,
I've never heard that you have to store sunbrella indoors.  The name implies it is made for outdoor sun and won't deteriorate.  I had sunbrella material and two work boats and both were outside the majority of the year with no noticeable issues with either cover. 
As far as the original post goes, I've used Sugarhouse and SewLong.  Both are top notch places that do quality work.  Sugarhouse is larger and they can crank stuff out faster than most other places.  Both are pricey, but you get what you pay for.  Personally, I like the material other than Sunbrella.  I find Sunbrella material is on the thinner side.  I like the waterproof material that is heavier duty, albiet it only comes in grey (or it used to?).  Sunbrella comes in every color of the rainbow.  The heavier duty material just seems to wear better though.

Less than a month ago, I called Sugarhouse Awning and inquired about having a snap-on cover made.  I explained that I stored my boat outdoors.  The person I spoke to said that snap-on covers could only be made out of Sunbrella and it would shed some rain but would not handle the weight of snow.
