K1W1307,
Those are the specs used in the US back in the 60's.
They came from the Land Yachting Bible least ways that is what is thought of the Book. Landsailing..... friom RC Models to the Big Ones. First Printing Circa 1973.
It would seem that we have made a few alterations to then but the Yachts are still very similar just the same.. The Book is worth the read.. If you can get a hold of one.
Ron
PS it is much easier to get through than the Tome was suggested.
Ron, I was reading that book freshly released when I was at High School (and I'm pretty sure I left school in 1966 and the book was in the library)! I started building in the 70's and believe it or not things have moved on in the last 50+ years!
The book has never been more than an interesting book to me, certainly NOT the bible of Landsailing. Even the Septic Tanks don't give it too much credence!
The Flat Earth society lives on!
It was either a different book or your memories are mixed up.. Us Old Farts di stuff like that.
Ron
Whatever, I have a copy and it's still way out of date (just like SOME old farts)
Whoa! Bitches!
May Hap the Publishers maked a Hoo Ha!
May Hap they are first publishing's of different material. WTF anyway. FActs is Facts, maybe we should apply Occum's Razor and perhaps Skin Schrodinger's Cat

Hi Blake
How is the new yacht progressing.(we seen to have lost track of what we where discussing here)Over the last week I have rebuilt aus230 from the Y frame forward , I found everything was to far out of alignment, Some how got things wrong while making some frame changes so it was easier to start again, Everything is nice and square now ,I have changed the rear wheel angles to 14% and also made the steering adjustable forward and back so I should be able to get everything balanced now.
Cheers

I'm not actually building at the moment...should be sailing, the Americas Cup ends today, but family disasters kept me from going. 'Tis the season here should have some sailing adventures to report soon.
...my fed 5 was like that (the Rocket less so), by the time I had the steering far enough forward there was no room for my feet to move. I ended up driving in the skinniest shoes I could find or just socks and more or less steering with my toes. If I hadn't sold it I was going to add "blisters" to the seat to give my feet room to move.
Blake
I wear boat deck shoes so I really don't have a problem. Steering may be a little heaver but that does not bother me much.
I thought I had really stuffed up with the changes I made, it took a couple of frustrating races to get it sorted again, Moved the steering and then it started to preform well again. Certainly better being able to adjust the steering quickly
Cheers

Hey you fellas on the other side of the Pacific Ocean.... What is with the Alameda Runway?? Damn! Would it ever make a fine Land Yachting Venue?? You reckon you could gain access??
Ron
[}:)]
Yeah! Ok. It is just that I have been watching The Myth Busters tonight. Love it when they Blow S%^t up
It was The Presidents Challenge Episode. I thought a Blind Man would see that the Hell Boys Fist part wasn't going to happen even before it was started but people want it done any way.. That series of trials were done at Alameda Runway as they called it so I went to Google Earth for a closer look. Damn I think Paul would commit murder to get a free shot at that sight Hey Paul??

that particular base was closed down, it gets used for a lot of hollywood scenes.
I think there are a lot of US military bases that have been pretty much abandoned due to budget cuts- if you can get access you would have an ideal place to play!
Here we go again, started to build the new frame for aus230, Not sure how it will go so I have decided to keep my current frame intact in case this one does not work out. main difference is 250mm longer axles and a plume type front.
Cheers
aus230
hmmmmmmm........
in that case Id better 'fes up Vic, Im working on my OTTmini, but the world keeps getting in the way.
I do hate working on things and not telling anybody about it, and the construction section gets a bit slow too
have fun
because we shouldnt, because its bad for us,because weve got a life
even as I start to build , I dont think I will fit in it, the kids are just drooling , looking at the awkward thing.
give me a T frame any old day
Some time ago we where discussing weights of class5 yachts. I just had a look at the plume factory class5 and there yacht comes in at 62kg. so I guess our yachts are not to far of the mark. Site can be translated to English (use Google translator)
www.plumefactory.fr/yachts/5-5-sport
To continue the theme, a while ago we were talking about...
Now that my son is partway (well almost finished) his engineering degree with Aero-Hydro dynamics and Composite engineering as majors, I have got the "best man in the street method for calculating the centre of effort" out of the senior lecturer in his department.
It is, wait for it... cut out a profile and hang from each corner with a plumb line across it! The windtunnel actually modify this some by moving forward from this point a small %age (not as much as 5%) depending on the draft of the sail. Apparently using the old traditional line to midpoint of the opposite side only works for pure triangles with no leach area.
Hate to say it, but "I told you so"
In regard Plume weight I am a bit surprised as they were always, in the good old days, the lightest of the yachts, seems even they have come to realise that very light does not work too well!
not sure how this center of effort thing works. Any diagram's on how the measurements are taken and where does the pilots size and weight come into the effect. All quite new to me and I should imagine there would be plenty of others interested.
Cheers
Vic
it also seems to be the fastest ones too!
So KIWI 307. You seem to be telling us to build the Chassis, less Mast Step, to the Rolling Stage Fit the Seat and a bunch of weight, to the point of EML (Estimated maximum Load) then start Dragging this lot about the Paddock, Sideways, on a rope until through adjustment you find a point of EB (Equidistant Balance) and at this point the mast Step should be placed???? No?
