      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

    I have to say, that all Ross boats are the sexiest looking boats on the planet!. Considering thier age (design) they still look fast (10 knots on the mooring)and have not aged! I have seen some butchered re vamps and adittion though! Sex on a stick for sure! imagine a 100 foot Ross in composite everything! drooolllllll!

    Shuzbot! so you guys do'nt get together for a Inter state or regional champs. I suppose if you did you would have to run a handicap system! geez thats a pain! Mind you getting all your different boats toghther for a regatta would show what boats and innovations are "HOT" Whats a Ross 780 that is 8.2 M long called???

    So if you 32:1 for rig tension, what tension do you run? Do you have a loose guage to check, seems like a lot. Six Pak has no where near 32 and seams to get enough. The best advice i ever got on rig tension for all boats is to tension the rig so that the leeward stay (cap) is not loose while sailing (in powered up conditions but not overpowered)and thus the rig will be straight sideways and in as much equilibrium as you can get. a loose leeward stay means your rig is overbending / de powering and also means you forstay is slack and you distance between you mainsail tack and head has shortened and thus has compromised your leech control. On interstella Overdrive we had a doulbe spreader set up that held the rig static (with pre set pre bend) and thus we had complete rig controll and quick upwind speed. Do not bother with loose gauges they are a complete sham. why well... they give different readings depending on ages, batches they give differing readings depending on wire type, diameter and where your measure point is. they are only good for you boat only for reference and when calibrated with a Load cell to give true loadings. I had a engineering guru from a local university run tests on 5 brand new gauges in 2004 and on a pre tensioned wire these things varied by up to 12% at the same point and when you move the measure point to the middle of the wire (more deflection) they were giving differing readings by 18-20% If you tension anything between two ponts the middle will move (defelect) more than the attached ends! thus these things are useless when comparing between two class boats unless everything on the two boats (wire type, batch, measure point, diameter, mast type, mast alloy temper...) is exactly the same! Also after reading all these posts i ask one question... Are there any two identical Ross 780's in the world any more??? what happened to the class rules around rigs, keels, ballast...

    do you want my bank account? heres my ross 490... doh! how do you get this upload thing to work?
  5. Ross 780

    Nice. but i hope you have not put any Alloy next to the carbon without isolating. (i am sure you haven't) just remeber that carbon has poor compression or impact strength so using E glass or kevlar in the mix is important. !

    Yeah (3 sheaves = 3:1) Many solutions to dothe same thing. Murray Ross ran a chute tru the anchor well on One tonner- Smack water jack, and his half tonner, and other boats, and it went thru a pulpit that had a round loop in the front. Worked a treat food for thought

    Kaiora bro, Can't draw a picure at present but....... from the mainshet block behind the traveller the mainsheet runs up to the boom then down to the single block on the traveller then up to another single block on the boom then alnog to the gooseneck, down thru a hole (with a oversize tube, 1 inch long, glued into the top of the hole to stop water from going below) at the mast step then from here the mainsheet goes thru a single block at floor level (beneath the mast) and joins into a 4:1 (this is actually a 8:1 as it pulls on the 2:1 on the boom)on the floor with the tail exiting thru the cockpit floor to a cleat system above the floor. (harken swivleing cleat set up.)_ The distance from the mast to the travller on the cabin floor is more than adequate to let the boom travel its full distance in and out!

    Thumper Mainsheet. If your a hard out race nut then you need to go to a 2:1 OFF THE BOOM TO TRAVELLER. with the boom end going along the boom to the mast then down the mast thru the cabin top and then running into a 8:1 along the floor and exiting out of the floor on a swiviling floor mounted cleat set up. The other end is your "course " downwind trim that is on traveller bock / cleat)this system is fantastic and worth the effort as it reduces clutter in the cockpit, weight on the boom, give a easy adjustmet up wind and good pumping down wind. Rig tension. 8:1 is like pissing into the wind. Either go with the Etchells system of adjustable side stays or do the Flying fifteen thing and tension your forestay with a 32:1 adustable systen that runs out the bottom of the mast. I presume your 8:1 is in the bow like in NZ. Also you could go radicall and do the Flying Dutchman thing (if rules allow) AND HAVE ADJUSTABLE SIDESTAYS / LOWERS AND FORESTAY that all link together so you can tweak rig tension and also rake the rig forward and aft for ultimate upwind and downwind performance! If you use heeps of vang / kicker upwind (to tension leech / set mainsail shape) then i would go to a cascade 32:1 kicker or 16 to one (and a winch) system and then go down to a 4:1 mainsheet (mainsheet effectivley becomes traveller, except in the lightest conditions) Food for thought??? 8:1 is more than ample for a fit person to haul rig tension on. If you run it onto a winch! then yes! But if you want to go fast... get some grunt on ya rig tension. and if you want to go real quick... Get a ross 490! Also look at your sheeting angles for you Jib! Murray Ross used to "whip Arse" with quite narrow sheeting angles on the self taking blades and guys with overlappers could'nt get close!

    we now have intersella overdrive in dunedin its now called spilt milk, it seems to have more freeboard than the others,or higher cabin? cant tell.do you know more? Yeah. it was built in Taupo and owned by a sailmaker. and is super quick in the light (or was) If you get a standard hopwood boats trailor and put interstella on it you will soon see the differences! it will sit on some roller s/ pads and be inches of others. The guy that built it did a few tweaks or got confused? Its got less rocker finer in the stern more freeboard... infact its debateable if its a ross 780! but with little measurement spec's at various "controll points" in the class rules then what do you expect?
  11. Ross 780

    having sailed ross 780's in NZ or a few years they are great boats. (mystery achivement, Interstella overdrive) however i have now found something even better,... the Ross 490! this is murrays finest and "sex on a stick!"
