The atlantic 42 is a beautiful boat! I loved the lines. I remember
in Georgetown, Exuma being on an Atlantic 42 in a storm and she was
rock stable. Much faster than ours, ours is definitely a cruiser, 4
heads, 4 births, large freezer, refrigerator, etc. The gunboat 48
takes some of her queues from the Atlantic in many respects. We were
trying to find a Shuttleworth 44 when shopping for a boat as we've
sailed and raced shuttleworths and loved the handling, but couldn't
find anything at the time.

And that's why I put in the actual polars of the boats. Many faster
boats out there, the polars allow a somewhat objective point of view
for a couple different types of cruising catamarans and can be compared
easily to other makes and models.

Cheers
