RAINMAKER DISMASTED OFF HATTERAS IN GALE

[Christian]

Multihulls have too much athwartship flex to allow the multiple shroud approach to standing rigging to function the way it does on a monohull.

Instead, spreaders, jumpers and diagonals are used to provide sufficient stiffness to the spar and prevent mid-section buckling.

The head stay, the windward shroud and the mainsheet act to support the rig and keep it from toppling over. The leeward shroud is often (literally) unbelievably slack.

Wrong. Plenty of cats (including many GBs) have lowers, caps, topmast shrouds, runners, etc. The decision comes down to windage vs weight vs cost vs lots of other factors. You can dispense with cables if you increase the carbon in the tube. Likewise, you can go without diamonds altogether, or a single set of diamonds, or inferior and superior diamonds, or double diamonds, jumpers...

But...single shrouds with single set of diamonds is a perfectly acceptable configuration if engineered for it.

Well - obviously not - unless something else fucked up......................

Generally speaking, I mean. There's no inherent flaw with single shrouds/single diamonds.

I'm not saying that the 55 rig was engineered right or wrong, I'm just speaking generally.

Well - generally, you would be right - but- it does require a stiffer/stronger spar than a multiple shroud setup. In this particular case it is impossible to say what didn't work without more detail on the failure mode - could be design/engineering, manufacturing, install or user error.

Yeah and we will never know unless they find the boat and that isn't looking too likely at this point.

Unless it gets run into by something, it should float for years...

Are you the same guy that got flicked for stalking here a while back?

Didn't you mean CDX?

100 foot wave and it would still be floating....I was thinking freighter or similar.

Well, it doesn't matter now, it's probably out of the environment.

Wasnt it 'Rogue Wave' that was abandoned upside down & then found years later restored on a Russian lake?? Ruski ca[t came across it, hoisted it aboard, fixed it up & had his own personal Yacht!

I thought this boat was cardboard fiber...

In case you guys haven't noticed, there is a parallel thread over on Multihull Anarchy. No real news there either except a cryptic post from Peter Johnstone yesterday with some sorta half-information. Still no detailedl post or days-in-editing interview. Instead we get a horse on a boat and a regurgitated story about ISAF on the front page to distract us.

It was Gulf Streamer, not Rogue Wave, that flipped north of Bermuda in 1976, stranding Phil Weld and a crewman for five days before a British container ship rescued them. It was later picked up by the Nikolai Ananiev, a Soviet freighter on her way to Lisbon. There, Gulf Streamer was transferred to another Soviet ship bound for Odessa, where the trimaran was restored and sailed by a member of the Odessa Yacht Club.

Dick Newick, right, with Gulf Streamer, a 60-foot boat he designed, and its owner, Philip Weld.[/size]

Rogue Wave was Phil Weld's next Newick trimaran, after Gulf Streamer and before Moxie.

P.S. More of the story here...

What's your personal interest in the Gunboat loss?

In other words, what harm are you suffering from not receiving your free information now, rather than later?

 

[fastyacht]

^haha good question

 

[DryArmour]

For such a skilled and intelligent group I kinda think we missed an opportunity to salvage a boat that except for the rig sounded like it was in good to very good condition. Did we wrongly assume "someone else" was already in hot pursuit? Discuss.

 

[Edith Bicknell]

Why salvage an inherently designed dangerous catamaran that is doomed to repeat the same catastrophic failure, when there is a perfectly good

Carroll Marine IMS 43 withthe rig still up floating around 200 miles off Nantucket?
