You might call Reef Industries about making you a tarp or even a tailored
cover out of their Griffolyn material.
http://www.reefindustries.com/griff/griffcovers.php It is used for field
covers and industrial shelters. On the boat shed I was going through a
30x60 silver tarp every year before I found them. They made me up a white
Griffolyn tarp that has been on for 4 years now and shows no signs of age.
It was custom made to the exact size I needed with grommets where I wanted
and cost about twice what a silver tarp costs but has more than paid for
itself.

I should say right off...I've tried poly and canvas duck.

I'd prefer to not buy a tarp but rather the material and make it.

The purpose of the tarp is to cover boat and trailer for winter storage
outdoors in a northern marine environment.

Given that, what would be suitable material considering cost, durability,
and protection of stored boat and trailer ?

Vendor recommendations would also be appreciated.

Thank you for suggestions,

Courtney
