Very interesting discussion…it is amazing how Mr. Roberts can explain over and over again how things work in the real engineering world, only to have the catamaran community hide it’s head in the sand and ignore the reality of Physics.
Seems, everyone wants a faster boat…BUT…they artificially paint themselves into a corner with self imposed limitations on Length, Width, Weight, and Sail area, Mast height…etc… You know one of the definitions of insanity is “one who wants to do things the same way they have always done them, but achieve different results.
I am starting to come to the conclusion that “racing rules” have done more to harm the development of boat design, be it power or sail…mono hull or multi hull…than any other factor. To get a very good handle on this topic read “Seaworthiness, The Forgotten Factor” By C.A. Marchaj. It talks about how racing rules have driven ocean going Mono Hulls farther and farther away from seaworthy designs, as designers have gone to extremes to “cheat” the rules…he speaks of how many of today’s mono hull designs have little to do with what is “best” at sea…and everything to do with twisting design perimeters, forcing them to design in a self imposed box. All for the elusive carrot of ‘fair racing”. Which for all practical purposes will never be achieved 100% …
Some where along the line things went way off track…no longer is it about designing and building the best boat regardless of limitations. “Trailing width” has become one of the “all powerful” limiting factors of Catamaran design. I find it amazing that everyone pretty much acknowledges this fact, and accepts it without protest. Instead of limiting “on the water” performance because of trailering…why not attack the real problem…the transportation of the boat to the water.
It appears that SC/ARC has made great strides in that direction, but the majority seem easily defeated by this problem… so quick to “roll over and play dead”. We sent a man to the moon, are you going to tell me we can’t come up with a better solution in transporting a 400 lb. boat?
I find it very sad that the designers of true innovation and superior products (like Mr. Roberts) who strive for the “best” within practical limits…who refuse to be put in a box…find limited commercial success, while those who are more adept at marketing than design/engineering, fair much better in the economic arena.
I will venture to say that until the catamaran community is willing to shake off its self imposed chains of “racing design rules” (which I don’t see happening), it will be artificially frozen in the doldrums of mediocrity.
The 38-year-old Tornado Catamaran’s current level of performance when compared to the “latest and greatest” drives this point home with undeniable clarity.
In our new “ politically correct” society”… we have come to expect that things will conform to “our reality”. Unfortunately…or dare I say fortunately…physics has some frustrating lessons for those that choose to ignore it's Laws...
