Thanks for the informative rant JB. Have you assembled any data points on the relative energy density in manufacture of the emerging alternative fibres compared to Carbon? I'm guessing basalt needs a lot of heat, for example, but I could be wrong there...
Take your point on gaming, but that happens aplenty in IRC - there are ways to work around the opacity to identify how to game the rule. I'd argue, however, that the transparency of ORC makes it harder for cheaters to get away with it. As rule owners and race managers leave it to competitors...
I count around 370 Australian IRC Certificates at present and guess maybe 450 ORCi at a quick glance - hard to say as some boats have more than one 2022 certificate listed. Also hard to parse the raw certificate numbers into "Offshore" vs "Inshore".
It's intruiging.
There are some real ORC haters amongst the top end of the blue water fleet. I'm not sure what their specific objections are as the two systems give pretty similar overall results. I'd imagine the transparency of ORCi would be an annoyance to some elite programs.
I suspect...
Likely 2,3 & 5. Boat is now well obsolete and beyond bringing back to competitiveness in this strong wind geography, but is still well suited to Med lighter air races. Ditto WOXI.
@Jono As you know I'm about you're size (albeit a handful of years older). I had the same midlife crisis 10 years ago and bought a Tasar. Yelling at a friend is more fun than yelling at oneself. Still lovin' it. Combined crew age currently 126...and thanks to Rob for the image
yep, you win on numbers but my gut still says theres more to it than just endplating. Moths may be a special case but presumably there are some insights to be gained from their extreme windward heel practices too.
Looking forward to a few keen minds chewing over this one. Would be good to...
If we assume that a sailplan's force vector acts perpendicular to the mast, a windward canted rig creates vertical lift, which should reduce apparent displacement and hull drag. A leeward cant creates downforce and increases apparent displacement and drag. I guess that's why the foiling...
