Feb. 2-7 — 9th Annual Zihua Sail Fest in Zihuatanejo, Mexico. Five days of parties, contests, potlucks, races, BBQs, auctions and chili cook-offs are what attracted more than 30 boats to last year's event, but the real payoff was raising money for local schools. These indigenous kids, many of whom are orphaned, can't attend Mexican schools until they learn to speak Spanish. Last year about $45,000 was raised thanks in large part to matching funds raised by the Bellack Foundation and Pete Boyce, and a $20,000 grant from Rotary International. To join in the fun and help some needy kids — even if you can't make it to the parties — go to www.zihuasailfest.com.

Feb. 6 — Pacific Puddle Jump Kick-Off Party at Vallarta YC in Nuevo Vallarta from 2-5 p.m. Latitude 38, Paradise Marina and the Vallarta YC team up to host the final get-together for South Pacific-bound cruisers. For details, email Andy or go to www.pacificpuddlejump.com.

Mar. 16-20 — The 18th Annual Banderas Bay Regatta is five days of 'friendly racing for cruising boats'. The sailing conditions and the Paradise Marina venue couldn't be better.

In fact, you'd have to be nuts to miss this one. The regatta is part of the month-long Festival Náutico Vallarta. For details, visit www.banderasbayregatta.com.

April 8-11 — La Paz Bay Fest. This will be the fifth year for this descendant of the (in)famous La Paz Race Week. An event for cruisers that includes races, potlucks, cruising seminars and other fun activities for the family. More info on Bay Fest 2009 will soon be found at www.clubcruceros.org.

Apr. 30-May 2 — Loreto Fest and Cruisers' Music Festival. This classic Baja event, started to clean up Puerto Escondido, draws a very large crowd of cruisers and Baja land-travellers for a chili cook-off, dinghy races and other water activities, the Candeleros Classic race, and lots of participant-created music. The goals are to have fun and raise lots of money for Mexican charities in Puerto Escondido and Loreto. Visit www.hiddenportyachtclub.com.

June 18-20 — Tahiti-Moorea Sailing Rendezvous, hosted by Latitude 38 and Tahiti Tourisme.
