There's a lot of options to consider. In the picture you posted - there's a front cover, stand up top w/rails, 3 front windows and side curtains, center front window would most likely have zipper to open and close to be able to access the front of the boat. Rear drop curtain costs more as well. John Mann out of Sodus did mine and I couldn't be happier with both the price and quality. Give him a call and he can walk ya through all the options.
