With any performance
catamaran take a look at the designed load capacity - basically the difference between light ship (basically the empty shell with all the basic
gear and half full
tanks, but empty lockers, no genset, no
solar panels, no
dinghy, no
water maker, no
code zero, etc) and the maximum
displacement. Generally the load capacity is designed to be about 1/2 the lightship
displacement.
Then have a think about how you want to fit out your boat, what kind of toys you want to carry, how much provisions, tools, spares and cruising comforts (paper books!) you feel you will need to
live aboard and have the life you envisage.
Often, going through this exercise results in either accepting the (relative) austerity of living within a smaller performance cat’s load limitations, choosing a higher-volume lower performance cat that has a higher load capacity, or, if
budget allows, getting a longer performance cat with its relatively larger load capacity.
There was a Delos video a few years ago when they interviewed a couple cruising in a
Catana 43. One thing that stood out was their extreme weight consciousness - no paper
books,
water rationing to keep their
tanks less full, limiting new things onto the boat with the
removal of old things, etc. That couple ended up getting a much larger performance catamaran so that they wouldn’t have to worry about weight so much. YMMV
