While your goals are definitely possible, you might want to re-think your choice of boats, as there are many other boats that would probably be far better suited to doing what you're planning. Even though you're planning on "coastal cruising", I'd recommend getting a boat that is built a bit more strongly, since you're more than likely to get caught out by a storm at some point.
I'd also point out that you and your wife should both take ASA 101-105 courses to build a solid foundation of sailing knowledge and skills that are going to be required for cruising. I would highly recommend you take the courses separately, as that is usually far more effective than if you take the courses as a couple.
Before you decide to buy a boat, I would recommend that you both spend some time on different boats, both monohulls and multihulls, so that you get a better idea of what you are looking for in a boat and which boats are best suited to you and your wife.
BTW, once you do have a boat, I would highly recommend that you start with daysailing the boat and working your way up to weekending, then longer coastal trips, then short bluewater passages... and shake down the boat very thoroughly before setting off for Mexico.
oh no, another beginner. I would appreciate the voice of experience on my BIG idea. My wife and I have been planning to purchase a sailboat and live aboard, staying close to the coast of Mexico. We seem to be drawn to the Hunter's, 35' to 40', 30k to 60k range. We live and work together, traveling (on land!) 365 days a year. Our total sailing experience would amount to me sailing around San Diego with my father 30 years ago and now some summer lake sailing. That and we are good swimmers! Are we just insane to think we can jump on board a boat and "learn as we go"? The replies to similar posts (at least the kind ones) always ask about the person's mechanical abilities. Both my wife and I , at the risk of bragging,are both excellent at mechanical work. I have extensive experience in electrical, pluming, engine,HVAC, metal fab and repair. good skills with fiberglass, ok with woodwork. My wife is smart as a whip, great at logistics (the traveling thing)and multilingual. I look forward to your input on our boat selection and other thoughts.
