A 45'
Bavaria can be handled by two people in reasonable
weather for coastal cruising. As others have noted, be sure to get the labor-saving
electric devices, even at the cost of complexity. I don't think you would need
electric mast winches as once the
sails are up, with roller and in-mast
furling, they will stay up. But you will need an electric
windlass, and depending on your age and fitness, electric primary winches would be nice.
Larger boats cost more than smaller ones in every way. As I bought my first
boat, a
broker made very clear to me the facts of (sailing) life: everything on a
boat costs by the foot. As a
trade off against the expense, larger boats sail faster, have more room, can carry more company and so on.
Practice
docking. In the Med, you will most often moor stern-to, so lots of practice backing down your boat is essential. You need to know where it will go. Here you really do need two people.
Finally, when leaving or arriving at a marina,
fuel dock, anchorage or
mooring,
motor as slowly as you can while maintaining steerage. The
displacement of a large boat will give it greater momentum than you can initially imagine, and you will be shocked at the violence and damage you can cause even in slow motion.
