I wanted some sort of tent type cover for sleeping under on my 20'
Tolman. I want to eventually connect it to the bimini via clear
vinyl. I bought some 1/4" fiberglass poles from Mcmaster-Carr and
drilled holes on either gunnel they would slide into and bent them to
form an arch. Then, I took some white polytarp and sewed some sleeves
to accept those poles. It works pretty dang good. I need to sew the
clear vinyl next and put on snaps to make it fasten tot eh bimini. If
all this works, i will eventually order Sunbrella to make a permanent
version.
