The project fast lightweight power catamarans - is possible?

I need to build a lightweight fast and economic power catamaran for the waters around the Canary Islands (waves about 5 '- 6'). The unit has to have a length up to 50'(maybe even longer floats - 60-70'?) and swim at a speed of 20knots at sea to 6'. Is it possible without the seasickness for passengers?
It has to have an open deck and seating for 25-30 passengers. I want to build it with the use of aluminum (or steel) and not to large diesel engines... Is it possible??

Just about anything is possible if you throw enough money at it.

I forgot to add - I do not have too much money on it The design must be simple ... I'm asking very seriously. If someone is able to design something like this, please contact at PW or romanewas@wp.pl . Or maybe someone knows something about this kind of boat?

Why open deck ? You mean uncovered ? It would require a very dry boat, and a climate with no rain, to avoid disgruntled passengers !

"not much" is not a recognized accounting term ! However, if people start talking about a lack of funds, boats don't fit well with that.

Especially if you have exceptional design goals in mind.

Gold Coast has some wavepiercer cats that may work.

I spoke with Warren Mosler. He has a yacht from Gold Coast - 50' wavepiercer cat:

http://www.goldcoastyachts.com/Yacht...50WP-index.htm
It is impossible to swim faster than 8 knots in a 6 'wave. The waves to 3 'can swim fast ...
Maybe it would be possible build such a boat but with longer floats - for example 70' and the hull hung higher for example 6' above the water? Maybe it would help?

Talking about ability to handle 6' waves is not definitive, without mention of wavelength, or direction of travel relative to waves, superimposition on swell etc
