I won't repeat the good
advice already given.
It is important that you, your crew, and your boat are ready for the trip - I recommend a few months cruising B.C. and/or the
Puget Sound first. Too often first timers leave in September (a great time) but are then delayed with problems until the autumnal storms start hitting. One friend is stuck in Crescent City right now as a result (he didn't think he needed a shakedown, and problems slowed him down). Going down the
PNW coast in the summer is problematic, as it is often foggy, and also the afternoon winds can be quite brisk (but at least in the right direction). Once past Cape Mendocino the
weather moderates, with another big change at Point Conception.
At the time I went south (1994) Charlies
Charts was badly out-of-date. I scheduled stops at several
ports south of Acapulco to Huatulco, only to find that all of the lovely
anchorages described in CC were completely full of pangas on moorings, and what
anchorages that were available were exposed, very deep, and/or otherwise poor. I think the CC guide is more
current these days, so check carefully as this stretch of coast doesn't have a lot of safe stops.
Golfo de Tehuantepec can be vicious, as others have said. But I disagree with the traditional
advice of "keeping one foot on the beach" to get through the gulf. I have known too many boats getting beat up and even damaged that way (beyond the expected sand-blasting). And since it is longer and slower it increases the chances of getting hit with the winds. You do not want to be
anchoring in 50
knot winds. We now know that these winds are caused by high pressure in the western
Caribbean driving through the low point in the mountains to the low pressure on the Pacific side, similar to the Chinook winds here in the
Colombia Gorge and the Santa Anas in Southern
California. Today's
weather forecasting is good enough that you will be able to leave Huatulco and directly cross the gulf safely if you wait for a window with no high in the western
Caribbean.
Central America is beautiful and interesting, but it is important to know the situation in each country before heading out. When I went south in 1994
Guatemala and
Nicaragua were no-go areas. We had an interesting stop at La Union, El Salvador in the Golfo de Fonseca but I'm not certain what the situation is now.
Costa Rica was a high point of all of my cruising, and worth a week or two traveling on land with a car rental. And the islands and coast of Panama are very beautiful and a great cruising ground in their own right (Bahia
Honda was striking). Times change, so get the
current info before going.
