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 Gulf's waters cover 500,000 square miles and plunge to a depth of 2,080 fathoms (more than 12,000 feet). This deepest part is Sigsbee Deep, an irregular trough more than 300 miles long, sometimes called the Grand Canyon under the sea..
