Do Multihullers Ever go Back?

I guess you are now far away for the topic of this post...

no not really because i want one of these in my Cat:

Don't fool yourself that the wheel actually does anything. It's only there for the owners kids to play with.

Just back on topic, I just found out that some days ago a unsinkable catamaran sunk. Out of the Australian coast an almost new Lagoon 500 in 35k winds opened a breach on a hull. The boat was American and the owner planned to sell it in Australia. The crew of 4 was saved by a cargo ship.

SNIP

Or at least it developed a leak and was abandoned and the owner contacted his insurance company with a claim. Lots of speculation about finding the boat and salvaging it.

I only have limited knowledge but some of the guys at SA (tough crowd there) are claiming it may have been an insurance scam. On the other hand the manufacture sure seems to be back peddling about how unsinkable the boat is.

A red courtesy light? I think you can achieve that.

Dude, you are confusing it with this Lagoon 500 that sunk too:

The Accident » Lagoon Litigation

This is another Lagoon 500 that sunk. It happened 4 days ago. Old topic?

Been discussed on CF for well over week. Lets get the facts correct not hearsay. Nearly 2 weeks now.
Vessel was abandoned not sunk. I believe the reason for water ingress is unknown at this time. Numerous possibilities.

All motor sailers go sideways.

Old topic. Already been worn out dude.

Lets get back to motor sailors and power boats, ok?

Love how topics go off topic. Just like normal conversations.

It was you that brought current models into play and it was referring current models that you said:

No, it is not hull L/B it is much more precise and complex.

Yes, I have seen a Leopard 44 hull, yes the chine helps to diminish very slightly the beam at WL but just some centimeters. The fineness has only to do with WL beam. The one of the Voyage 450 is much smaller (even consider the chines) and has also a much finer entries (the forward underwater part of the hull).







and it really seems that sometimes your opinions are exaggerated. You said about the Voyage 440:



and later said about the same boat:



What really seemed to be a terrible design characteristic (sound like bombs are going off under them. Friends of ours with one complain that their feet hurt from the pounding and they can't stand in the cockpit or saloon when going up wind) is after all just a trade off with advantages also (lower CG) and if the disadvantages were so bad as you say, to the point of be impossible to stand up in the boat upwind, nobody would want that boat.

Those owners of a Voyage 400 again say it an a way that seems correct to me:

"Does the bridge deck slap or pound? Yes, again under certain circumstances. Like the high speed bursts, the weather situation has to be just right for this to occur. Despite what some brokers and dealers will tell you, ALL CATS POUND under these conditions. Some cats, with lower bridge decks, will just start a bit sooner. What is important is that most catamaran manufactures accept this as a fact of life and build heavy reinforcement into the bridge deck. It is also interesting to note that mono hulls also pound in heavy seas when going to weather. It is not quite as loud as they pound only on the lee side of the hull while healed over. "

Our Boat

and I bet "caradow" would not have said this: "Oh yea one more thing after falling off waves in monohulls for years a little wave slap to me is very tolerable." if he could not stand up in the saloon when the boat is sailing upwind.



No, you are wrong personally I have not any interest in that kind of boat but I have in boat design and I try to be objective. Personally if I could I would have a Dragonfly 35 or a Farrier 39 trimarans, both more uncomfortable in several ways, wet and faster boats and that would not pound less since pounding has also a lot to do with the speed. All boats are compromises, I like to have fun sailing and I am not yet old enough to be wise

Polux,

You don't seem to get it.

I have never heard of anyone including owners consider the Voyage range of Catamarans as performance cats.

They are an older design comparatively these days with cosmetic updates (evolution) on the recent models it seems to me.

By comparison with another SA production charter cat, Leopard in the 42-46ft range has used 3 different designers (also design concepts) in the last decade whilst the Voyage hull appears essentially the same.

Voyage are designed for and seem excellent in charter in the first instance and many of those design features also make them excellent cruising cats as indicated by numerous proud owners.

But their specs simply do not a suggest performance cat and any suggestion is misleading.

You certainly are doing plenty of cat research. Are you looking to purchase one?

Cheers

Some generic cat performance numbers to consider
Beam to length ratio
Less than 10.5 Slow- go buy a mono
10.5 – 11.5 Baseline for good sailing
12.5 - 14.0 Mod to high performance
14.0 – 20 Racing cat
Bruce numbers
1 Slow
1.3 – 1.4 Good cruising
1.5 – 1.9 Very fast
