Joyon & IDEC have nothing on this dude's ride:

Hulls & Ama's made out of huge alu I-beam's...while the actual beams are out of tubular trusses.

The young chap expects to finish anyday now and immediately set off on an arond the world solo cruise.

Stay tuned folks, this is sure to entertain <img src="http://www.catsailor.com/forums/images/graemlins/tongue.gif" alt="" />

Entertain? Sounds and looks more like an accident waiting to happen. One would think it prudent to at least give the craft some serious testing first.
10 out of 10 points for doing it.
10 out of 10 points for trying something different.
0 points for not testing his creation (if I got it right).

Just read up on his other Esquire article " I do not have a death wish "

He is finishing work in San Francisco and plans to do some bay sail tests, then transit to Long Beach prior to starting the circumnavigation.

Hulls are filled with foam. 8,000 lbs, $25,000 budget. Build in about 3 months (goal was 2). Deadlines for departing keep slipping. 1st Naval Architect walked away from it when he got the willies about the around the globe attempt.

Check out the boat layout & diagrams...the beams form a "X" at the main hull.

Looks very weak for the racking it will need to take.

All welded alloy...so he's lost the temper strength at the weld areas.

Yikes!

You think it will fail before it gets out of cell phone range? <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" /> EPIRB is more like it, and a liferaft or two. BTW: Mast looks like a standard industrial alu extrusion as well?


Seriously, he obviously have got some feedback since he says he dont have a death wish and will do some testing. Hope he tests it hard enough.
Looking at the design, I think living aboard will be a challenge in itself even if it holds together structurally. Flat bottoms, very narrow main hull for use as living quarters, storage etc. A metal boat so it will be very noisy inside.

It looks weak cos it ain't finished, the renderings of the finished boat make the beams look pretty sound to me.
This is the kind of adventure I love, good luck to the guy. [Linked Image]

Did you see the Volvo 70 DVDs?, it cant be much worse than carbon. <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
Everytime they would ease the gennaker sheet from winch the entire boat was like a giant oildrum (not good for light sleepers).

I don't see this thing floating on it's line, it just may be a submersible.
Then there is the issue of twist. One can only hope that when it comes apart no one is harmed in the rescue effort.

I admire the spirit, but really now...come'on. There's not much chance of success on this one. The flat bottom is going to have terrible sea action, the narrow width of that hull has very little room inside, the aluminum is going to be incredibly noisy and COLD, and while I think his truss system on the ama supports seem to be OK, I really question the attachment method to the amas (rather the lack of anything appearing significant).

I like the nice sharp edges on the house/coffin. That'll be great to get slammed into. I hope he got his tetanus shot.

Haven't managed to find other info on this one, but is he trying to breake any record ?
It will surely set a new record for ugliness.
I have seen a few years back on Discovery Channel a documentary about a young kid rounding the world in 7,5m boat named Lionheart or something like that. No fancy boat , no fancy equipment, just ....optimism.

I would love to have a neighbour like this tincantri guy. He deserves a lot of apreciation. Pioneers, explorers, inventors have a large dose of insanity and optimism. Insanity overcomes fear, while optimism overcomes the lack of reality sense.

He's a winner no matter what will happen. Eh... I hope he doesn't injure himself too bad, but some scars will represent cool medals.

I'm near San Francisco and going that direction in a week. If somebody tells me where it is I'll go and snap some pictures.

THere is a long thread on Sailing Anarchy on this fiasco...someone there posted they have seen the boat at the SanFran site...and walk by in regularly...maybe you can get in touch with him to figure out exactly where.

Ever try holding on to an aluminum beam or mast when it cold? It just sucks the heat right out of your hands very quickly....big heat sink! I guess you could over come this with enough insulation...but the housing is incredibly small (was it 6x8x4?...stated in the second article I listed). So, once you've got your foodstuffs, minimal gear etc (spare sails??), where will you fit reasonable insulation?

I hope he's though about foot traction...alu when wet is very slippery, even with good boots on.

The second article I posted states he is trying to become the 1st American ever sail solo around starting from the West coast. Apparently only 1 other person has done it, a Canuck.

I'm heading up to the city Thurs. Who knows where it is? Looks like East Bay somewhere from the pix. I don't know a boat yard in SF with that many weeds in the background. Vallejo, Berkeley, Oaktown, Alameda? I'll go check it out if someone let's me know.
