Brandywine the world is rapidly adjusting to the beam of catamarans.
Docking (if you want it) is available anywhere in the
Caribbean, as are med-moors throughout the
Mediterranean. No, with the beam of a large cat you will not be able to transit the french
canal system, but apart from that you should find little difficulty.
Think of it this way: the
shallow draft in relation to a
monohull will actually increase, rather than decrease your options. Even if a marina does not have
docking to accomodate your beam, they will often have a wall that you can tie alongside. If a marina does not have a travel-lift or crane up to the task, understand that most cats can be left on the bottom while the tide goes out for
cleaning, applying antifouling and yes, even some underwater
repairs. Most importantly for the cruiser, bear in mind that cats have none of the tendancy of monohulls to sway while under
anchor and - here was the clincher for me, the shallow
draft allows you to gunkhole in spots that are way off-limits for any mono of close to comparable size.
