I agree with Maytrix, although I understand if niece is a racer the desire for a monohull, but the cockpit area and front tramp on a cat are so much better for relaxing, dining etc. my 2c is two weeks with 5 people, that mono is going to get small quick. I look at it this way, the cockpit of a 40 or so foot cat is like that of a 70 ft mono, this is vacation after all...but that is just my opinion. Add on the longer sail to and from the SVI possibilty, that added comfort and space is really nice.
