Chartering, to understand what your priorities are before buying... you will need qualifications to charter without a skipper and acquiring those will significantly aid your decision making.

There are plenty of things to get confused about, and plenty of additional equipment... and skills to operate... over small boats. The basics of making the boat sail are the same, just slower and with a lot more momentum (which is why learnin to -sail- on a big boat is a mistake). Once you know how to make a sailboat go from point A to point B, add navigating (and the gear that your boat has to do so), reading a chart and a pilot is a skill all to itself... then learn to anchor (again, with the gear your boat has)... then learn to reef for strong winds, and also learn to read the weather... then learn about 12V systems including batteries and chargers...I am very new to sailing. I know how to kiteboard and windsurf and sail sunfish and lasers but big boats with interiors were a complete mystery as of a month ago.
I opted to just buy one and figure it out instead of chartering. I am happy about it. Sailing moves a lot slower than I expected and I don't think I'd really get much use out of a charter. But because there are a ton of little improvements and maintenances you need to futz with on a boat you own it's a lot more fun going out and testing vs. having a clean boat that you know is going to work.
You probably don't want a true bluwater boat. My 26' boat doesn't even have an inboard motor and there's plenty of things to get confused about. Having a water generator, two autopilots, radar, lifeboats, working refrigerators etc would just be a mess
If you or your husband are hands on or are mechanically minded and adventurous and have bank then a 34 footer is not an unreasonable starting point, but most people either gain experience crewing on Friend’s boats or start small. (Teens to mid twenties)
