cruising cats are designed to handle the load. See Exit Only'

of 4 on a Privilege
The non-stop distance you plan on cruising will very much determine how much storage and weight you'll need to be able to carry, coastal cruising is much much less demanding than crossing big oceans. The heaviest items aboard are fuel, food, and water. All forms of energy. You can turn fuel into water. You can turn sun/wind into energy for water, harder to turn it into food :-)
The other thing is how much elbow
room you like...it's a personal preference. Katie Kat, a seawind
1000 (33' before the extensions), did a lot of long distance cruising. See the blog
Also read, Sensible Cruising, The Thoreau Approach
. A bit old, but timeless information. I've always enjoyed bigger and faster boats. A couple years ago I chartered a Catana
50, and for the first time, thought, the gear
, lines, etc are just too big and too much load. After that trip, I read the Sensible Cruising book and have changed my approach. I still like good performance, but appreciate more and more simple systems that are easier to handle and maintain.
