This is a how long is a piece of string type question! There are literally hundreds of boats that are suitable, but none that will be perfect for all situations. For example, traditional ocean going yachts (long keel, small cockpit, flush deck, sturdy rig) are less than suitable in the Med where a big cockpit, lots of ventilation, large sail area and powerful engine are preferred.

This is not to say that you can't compromise and overcome shortcomings in particular situations, but if you do get any responses from other forumites thay will reflect their views which may not be the same as yours.

You also need to give much more information such as your experience, crew, preferred lifestyle etc to give somethiong for respondents to hang their advice on.

For example, my immediate response would be a Moody 376 for a well organised couple. However they are a "down below" boat and far from ideal in hot climates, but very seaworthy, comfortable and well built. In the Med however, I prefer my Bavaria 37 - great cockpit, stern bathing platform, good light airs performance, good motoring - but not a good choice for long distance cruising even though structurally quite capable.

Hope this gives you something to think about - and by the way there is no such thing as a perfect boat, only the best compromise for you!
