Grady White is using a material called Stamoid Vinyl on some of their tops. I like it because it is stronger than the bimini top material and much lighter than the fiberglass top. Cheaper too. I have seen this on two 2011 GW boats. Stamoid can be found on a Google search. I am considering having a top made of this to replace the bimini on my 228G. I do not know if this can be ordered from GW or the cost. But, online it is $26.50 per yard for the 12.5 oz product. Any comments will be appreciated.
