You shouldn't have any problem with most 38ft catamarans.
Jetti and I lived on board our 32ft performance cruiser Eclipse for 5 years and, from the UK, sailed to the Caribbean
, up to Maine
, down to Cuba
and C America. So first, is that the sort of cruising you mean by "extended cruising'. Or do you mean non stop round the world
Eclipse was a performance cruiser and won many important races before becoming our live aboard home. So the loading capacity was marginal at about 1500lbs.
However in that weight we carried enough food
for 3 people for an Atlantic crossing
, also a sailing dinghy
, a sewing machine
, most of the tools I used to build the boat, 3 computers
, a solid fuel
stove, 8 sails
, a generator
, lots of books
and DVDs, enough fuel
for 200 miles motoring etc etc. And we could still average 9 knots all day and peak speeds of 14-16 knots were common.
We now have a 34ft catamaran
, Romany, a proper cruising boat this time. With the same sort of gear
on board we are still floating above our marks even when living on board (last winter we sailed from Annapolis
to the Bahamas
; Romany is now in the St Johns river, Fl)
I said "non stop round the world" earlier. The first catamaran
to sail round Cape Horn was a 30ft Oceanic sailed by Rosie and Colin Swale and their two young children
(one was born on board). They sailed non stop from Australia
round Cape Horn and back to the UK in the early 1970's. Look for Rosie Darling and Children
of Cape Horn at Amazon for more.
In proportion if a 30 ft cat can carry 2000lbs load, a 34ft cat 4000lbs then a 38ft cat can easily carry 5500lbs, as loading capacity depends on the cube of the length (by and large)
And 5500lbs is a lot of beer
, especially if you brew it yourself.
You can see more about my Eclipse and Romany as well as lots of basic background information on catamarans on my website, below.
I hope this helps
