The
current going north in the
Yucatan channel turns into the
Gulf Stream off
Florida and the rules are the same...
Cross at narrowest point, do not sail directly into it, avoid it like the plague when the winds are out of the north on the back of northerly lows.
Get your southing on the edges.
Lorenzo has it right, spend your time and
money in the Yucatan, Isla Mujeres and Puerto Morelos are great places...free anchorage in Mujeres and free moooring balls in Morelos.
Marinas are excellent and
cheap, we paid $25/day for a 55 ft boat!
Clearing into
Mexico is a day long or more $250 process using an agent most easily done in Mujeres, Port
Captain in Cozumel was difficult to deal with.
But we stayed in
Mexico for 3 months and thought it was one of the best places in the
Caribbean... nice people, safe and low prices.
South from Mexico just stay out of the current and try and get southing on northerlies that occour every few weeks.
Do not trust any chart plotter south of Mujeres, I use 2 different systems and each was out by 400 yds but in opposite directions. While moored inside the reef one showed me outside the reef and the other showed me at a bus stop outside the church!
The
charts are reasonably accurate it's just that Mexico and it's
reefs are not where the plotters they think they are!
We missed out Belize and Rio Dulce because we draw too much
water.
