While CC have more living space than aft cockpits as a general rule, the newer boats out there Jeanneua, Benneteua, Catalina aft cockpit boats, are putting in very large aft cabins. So one is not restricted anymore to just CC boats to get the large aft cabin. But in both designs it comes at a price; storage. Cockpit lazzerates are smaller or non-exsistant. Finding place to store dock
lines,
fenders, extra sails, wash stuff and other gear can be problematic.
Also, CC cockpits are typically very small. Lounging out with more than 3 people, especially when the weather get bad, can also be a concern. With most tables extended out eating with more than 4 people around one will have to find other means to entertain guest.
