Miami  Chart info

Looking for info from someone who has a chart of Miami area.

What is the depth at 12 mile line. How far off the coast are you at 60 foot dept.

Assume location east of Miami Beach out of traffic channel.

For comparison. At Galveston the 60 foot line is about 15 miles offshore and the 12 mile line runs about 45 foot.

Every place is different.

When I was running subs out of Charleston it took us 6 hours to get to water deep enough to submerge.

At Guam you could submerge at the pier and the land sloped down at 45degrees to really deep depths.

But here in Texas you go miles and miles with little depth change. The whole Laguna Madre area is only 8 feet deep. Land on shore slopes at 1 foot per mile. So for here it is not surprising that it is only 45 feet at the territorial limit.

>How far off the coast are you at 60 foot dept.

About 2 1/2 miles.
