As a die hard alloy boat owner and also a bit of a die hard mono owner I was wondering were there any manufacturers of quality alloy cats.

I would love to know names and prices of quality alloy cruising cats in the 40'ish range...

Only real requirements are a rugged boat that sails well. I can trade living space for performance since a "small" 40' performance cat is a lot bigger still than my 42' mono. Doesn't need to be new either, in fact prefer a couple years on her to lower cost and let someone else do the shakedown...

Thanks for th help

Oh and don't get crazy, I am not converting...just curious

Re: Aluminum Catamaran Manufacturers

Allumarine in France, who made my boat make some semi production aluminium cats. They have also made quite a few one offs.
I have seen some other French aluminium cats "banana" I think

Re: Aluminum Catamaran Manufacturers

Aluminum doesn't become very favorable for use in catamarans until ~50', so finding an aluminum cat around 40' that still carries cruising loads and isn't an outright dog will be difficult. Here is another: Hy-Tech Marine, Inc. - FastWater 52 SailCat

Re: Aluminum Catamaran Manufacturers

Weight mostly. The scantlings required for aluminum catamarans are heavier than those for fiberglass or wood until ~50', when they become equal and even lighter. To a lesser extent, aluminum building techniques are relatively more expensive for smaller boats.

Re: Aluminum Catamaran Manufacturers

I was going to ask that.

So, it reads like Aluminum is preferred for cats over 50'?

Thanks

Re: Aluminum Catamaran Manufacturers

Hello Foolishsailor,

Here is a cruising cat made from aluminium;

http://www.ngyachtdesign.com/multico...oile.php?id=14

42 ft and 8.25 tonnes,so it is definitely a cruiser and not a racer although it is a bit lighter then a lagoon 400 I believe.

Cheers,
JJ

Re: Aluminum Catamaran Manufacturers

It would be interesting if someone could find some displacements for aluminum cruising catamarans under 50 feet. I would imagine many people would like to see the facts.

Re: Aluminum Catamaran Manufacturers

I am most familiar with monohull construction. For an equivalent strength, aluminium is lighter than a solid fibreglass structure, about the same same as a cored fibreglass structure and heavier than an epoxy laminate cored structure.

The limiting factor with aluminium is that a skin thickness less than 4mm is not practical. Welding a fair structure with a skin thickness less than this is difficult.
In a monohull this sort of skin thickness would be used on a 30 foot boat. For a catamaran the length is somewhere around 40 feet.
So below 40 feet an aluminium catamaran is likely to be heavier. Above 40feet the aluminium catamaran will be lighter than a solid structure below the waterline and cored above. Above 50 feet it is likely the aluminium will be slightly lighter even compared with a cored structure.
An epoxy carbon/Kevlar/E-Glass cored structure will be lighter again.

A cored structure is more prone to damage (delamination and water penetration) and this must be weighed against the strength and cost saving advantages.

In short a monohull of less than 35 feet, or a catamaran less than about 40 feet is not sensible to construct from aluminium, unless there are specific requirements.

Re: Aluminum Catamaran Manufacturers

The listing on the second one says it is made of aluminum, not fiberglass.

Either way, it looks nice to me! It is larger than what you originally said you were looking for. Aluminum build at 48' hits the sweet spot for aluminum much easier and better than 40'.
