I am looking at lots of good priced local canvas tops or bimini tops, but aside from beam width how do i make sure it fits the contour of my windshield? i have a 74' Galaxy bow rider
Measure the height of the Windshield. Stand in the boat and determine the approximate distance your head is above the base of the windshield. Make sure when purchasing the Bimini that the support arms are equal to or greater than the measurements that you took.
