I think this is a VERY BAD idea unless you have cruised before. And MORE important that your soon to be wife as cruised with YOU before! Last year checking into boats I was interested in I came across more than 1 boat that had been bought by a newly married couple, cruised a few months, put
on the hard, and the couple went their separate ways. In other words it only took a short
cruise to break up a new marriage!
On the other hand if you and her have cruised together I think it is a GREAT idea. Send off application etc to the charter companies and they will let you know if your experience etc is good enough for them as it doesn't matter what any of us say. But unless the 2 of you have cruised together I'm not sure it is a good idea even with a crewed boat (not counting one of those 70' yatch thingies)
PS - Mark do you call Nic Gazelda when she can hear you?
