the gulf of Mexico is about 850 miles wide at its widest point. I'm not sure where the widest point is, but i hope this helped. That is all the info I could find to answer your question. I was wondering that same thing to plan a boat trip to Brownsville Texas from where I am now in Ft. Myers Florida.
There also may have been some vertical movement forcing the peninsula upward and the gulf downward. 1  The gulf is about 750 miles (1,200 km) long and an average of 95 miles (153 km) wide (about 200 miles [320 km] at its mouth). The gulf has a total surface area of 62,000 square miles (160,000 square km).
