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.
The total coastline of the gulf measures approximately 3,540 miles from the tip of Florida to the tip of the Yucatan, with an additional 236 miles along Cuba. The Gulf was created first by continental plates colliding in the Late Triassic period, around 300 million years ago, and then by the sea floor sinking.
