Aluminum Catamaran

[Dulcesuenos]

I see the horrors some aluminum mono owners have had and wonder why would anyone want to double it. If it was a good idea and cheaper wouldnt more builders use it? We had a aluminum 25' rib which when new was stupid expensive and it too had nothing but electrolysis issues. Welds always coming apart always leaking it was crap..

Many monohull voyage boats are made in aluminium and have no problems at all (OVNI, Allures, Garcia and many more). However I agree that for doing that it is needed experience in what regards electric installations on aluminium boats and the building is also more technological. I would only have an aluminium boat or made by a brand with a huge experience or made by a shipyard also with a big experience and they are not many. You can find some in Holland and France.

The Mumby is more of a performance design with less creature comforts and lighter built which may mean less material costs. I don't think the interior fit out is that hard, foam blocks and flat glass panels coved together. They are cheap and fast to build compared to a glass cat.

The people I've met who built theirs, don't seem to agree. They take as long and cost as much to build as mine did.

Aluminium is a great material for boats when designed and managed properly. See Link below of excellent example of high quality execution. I think it would make a great catamaran for cruising.
