Build yourself a boat and do a lap, crazy or not?

Gray matters
He who cares
Looked after,
not forward
He did it his way
He He He.
Does not rhyme
Welding broke
F'ing stupid
trying again

 

Looks like he made it back in about 10am this morning to San Francisco

K9

 

The story continues!!!

 

Tell that to Francis Joyon.

 

But the one developed on this thread had ABSOLUTELY NO HOPE......

 

As the Cowardly Lion said in The Wizard of Oz---"You can say that again".

 

Yes

 

Geeees, this idiot does NOT need encouragement, read the full thread please and study the pics, bloody fool and dammm dangerous.....

 

Ain't most small boat sailors tho Mas - that's what makes em what they are!! Hell for 'crazy' read 'individual' read 'ecentric' all depends who you are and how much money you got really - you do the same things, just different price levels!

 

Read his exploits - he ain't anyway near "most" unless the most are those locked away in padded cells & wearing those funny jackets.....

 

Hmmm, I've only touched this thread partially earlier.... Now I've made up my meaning......

First:
There's no reason why it shouldn't work with 3 boxy shaped hulls......

But;
Welding must take ino the fact that fatigue is a factor to consider, badly shaped welds must be excessively strong to take that. Saw a lot of strange welds on the pictures. (http://flickr.com/photos/mmm_beer/tags/tincan/)

Alu, doesn't like fatigue too much, so the stress has to be spread out, doesn't seem to have been in the designers mind here, that issue...

Escape hatch in the water...hey, its a BOX, with (a lot of) beams, how difficult can it be to calculate weight displacement??? Probably the main hull should been a bit wider/ deeper.

The X-shaped frame, all stress in one/ few areas, the bolting of these to the hull... The washer, on one of the pictures.... The vertical beam holding the upper/ lower arm at a distance, not added diagonally strength in the beams, arms. Man..... ( http://en.wikipedia.org/wiki/Truss And Scroll down to "Cremona diagram").

Why not do an estimate of the stress....

When this hits a wave in 15+ knots, the stress to the side of the bolts will be formidable, the bolts are of stainless steel the holes are Alu... guess what will hold... to redrill and replace bolts in high seas, make it quite possible that he'll without any big fuzz get off with cheaper manicure next time...

If i understand it correctly; he's done a stunt just a little different like this before, which is probably why he settle for a low budget boat, that's still no excuse to not consider stress/ weight/ shape/ rescue issues more seriously.( http://www.amazon.com/review/produc...dphist_3?_encoding=UTF8&filterBy=addThreeStar )

He'll need some luck, or a better kind of medication.

PS, I have not seen any pictures of the repair/ changes, so there is a possibility that there's serious improvement to this project that I've not come across yet.

Or not....

 

Damn

I nearly got excited

thought he's at it again

but oh no

This tread is still DEAD

DOES ANYBODY really know what has happened to "TIN CAN" in the mean time

Just a suggestion
if you want to debate these kind of boats

Start a New Thread

Dont hijack "Tin Can"

 

First, I want to appologize for not reading the entire thread before going off half cocked meself.
That said; I don't think that there is anything wrong with an experienced sailor having a boat built, rebuilding a boat, or refitting a boat to "do a lap".
Rushing any job and doing it on too small a budget is: what appears to me, to have been the problem... and I don't know enough to say wether it was a design flaw, or a construction error that caused this guys problems. My hat is still off to him for trying something new.
Again, my appologies for not reading all the way through before diving to my conclusions.
