Catamarans have for the
home builder are that they are cheap and relatively simple to build,
on the design.
The hulls can be simple V shaped stitch and glue constructions connected by a timber bridge deck, as in the famous Wharram designs.
Multi hulled boats have been in use among fishing and seafaring communities since time immemorial.
The word, catamaran comes from the Tamil language of Southern India where they were used for fishing.
And of course twin hulled vessels have long been in use in Polynesia.
The Polynesians covered huge distances across the Pacific in their quest to settle some of the worlds most isolated islands.
Their vessels ranged from small outrigger Proas for fishing to enormous catamarans for voyaging.

For the home builder the greatest advantage is the ease of construction
At sea the advantages are numerous.
the early days of western sailing multi-hull design, there was
considerable fear of capsize.
The worry was that where a displacement mono-hull would self right an overturned cat wouldn’t.
This lead to some being equipped with enormous flotation bubbles at the top of the masts.
Since then it has become established that unless the boat is very light and being sailed at extreme limits, a capsize extremely unlikely.
Having the accommodation of a cruising multi-hull divided between the hulls does limit the size of the cabins.
This could be a disadvantage for small boat cruising and for living aboard.
Many trimaran designs attempts to overcome this by having a larger central hull with smaller outriggers.
larger catamarans with large bridge decks and wider hulls are becoming
as cruising boats.
