We are currently in Isla Mujeres on a vessel that has a draft of nearly 6 feet.
==================
The difference will be negligible. Our tides are around a foot at most. A vessel with a 6 foot draft can enter at San Pedro and anchor but would need an experienced guide to go south from San Pedro inside the reef. I wouldn’t do it which is why I passed on buying that 48’ ketch as the draft was 6’. To go south with a 6’ draft by themselves they would nee to go out and come back in at English Caye.
