On most catamarans, entering the saloon
from the cockpit
is kinda like going from your patio into your family
room. Doesn't get much easier than that. Granted, you'll have to go down a few steps into the hulls to access the head(s) and sleeping cabins, and some designs have the galley
and nav station down in a hull
, as well.
33 and Newport
30 have pretty easy climbs from the saloon to the cockpit. And when you get down below 30' it's usually just a couple of steps.
A lot of the easier ones, though, won't have a bridge deck
to step over between the cockpit and saloon. While that makes it easier, it can invite problems if the vessel gets pooped (takes a wave over the transom that floods the cockpit.)
It can even sink a boat if tons of water
fill the cockpit and wash into the interior
. I once read of a boat that sank in 30 seconds off Puerto Rico
while sailing without any washboards in place on a bright, sunny day.
