History, Science, Design, Art, Sailing

At about 35 min. into this, they discuss the hesitancy of sailing in a 29 knot, 2 metre wave seas, and it was reassuring that the ‘spidery’ ship could have done it easily.  It is understandable that after the win, the skipper and the owners have a lot to celebrate, and not time to ‘oncore’ the feat with a show of bravato.

But this concern goes to the design. If a max of 29 knots is it, then this design should be considered as unsafe.  It may be that the tri-wing mentioned and discussed a little bit might be more flexible or reefable, perhaps not require the 240 foot height, although a 747’s wing is certainly adaptable to higher than a full gale of breeze (flying at 650 mph).  It’s not the wing; it’s the hull, stupid.

The catamaran is a great idea … not.  It was only good when it was used as a single outrigger on a main dug out hull by the polynesians… and they were paddling it.   The Aligahi looked like it was skippered by a pilot who just found the keg of rum, and didn’t think they needed the ballast anymore.  It was a shameful display of wiggling towards a mark.  And gave me another reason why I hate sailing the little things that family members con me into when we’re at the beach and someone goads me by saying ’ He’s a great sailor’ .  Yeah, well wiggle your body around while I tell everyone, ‘She’s a great dancer’.  (of course that’s not fair, ‘cause the cat. can’t do anything else.)

Now that brings me to the Trimaran… a 70 percent improvement over a cat, but slill lacks the stability of a pure monohull.  Now that doesn’t mean it can’t be radical, or even act like the Trimaran as it sails healing to one side…. just at a sharper, more dramatic angle, perhaps … but not necessarily …. but in an emergency, it is survivable.  Anyway, using the beautifully curved daggerboards, the wing, the ballast shifting pumps of the Alighi, or even a mechanical collapsing of the trimaran into a monohull in an emergency condition would test the true meddle of the sailor and the ship.

And thanks, EQ.
