Heavy-duty Harbor Master boat cover, 14-16', 68" Beam

This boat cover is brand new. I took it out of the package and tried it on my 14' Larson, only to find out it's not wide enough to fit properly. So I need to order the next wider size. This cover fits 14-16' boats with a 68" beam. I paid $74.37 + tax for this at Walmart.com. Here is the description from the website:
