Intuitively most skippers will turn toward the rising AMA to bring it down, only those who race beach cats and fast foilers will know to turn away.
Standard for everyone that has pushed any sailing boat hard downwind. True of anything from a laser to an ocean racer. So should be intuitive for him

Some good wind forecast right now on the lake
If they don’t do it today, Sunday/early Monday looks to be slightly better.

After that, it could be too quiet until the next front comes through. Typically, they are roughly 2 weeks apart this time of year, which means just before Xmas for the last chance. If it transpires that way, it could be a pretty boisterous S2H for some of the fleet as well…..

Greenbird might look the same, but it was smaller and lighter and built with a different philosophy in mind. take advantage of the gusts. Horonuku is heavy and much larger and builds and builds and builds speed. It just needs a consistent wind.
And a much longer course. Greenbird did it in about 1 mile of distance, NZ is looking at 5-6 miles.

If you look back on the iron duck story, it gets to be a matter of nerve and fearlessness. The one driver thought that the iron duck could so faster than the record that it set (prior to Greenbird), but he said it would have to be someone else driving it!

Even if they get the exact conditions to break the record, how far do you push it? There a very few Chuck Yeagers that are totally fearless and can push crafts to their limits of breaking up. It is a matter of cheating death.

FIFO maybe?

“Mt Ive has a very good 2 strip airport that is Kincaid capable. All the accommodation will have been booked out a year ago. It will be camping only. The only access to the lake for speed week is via Mt I've. The lake is about 30 km from the homestead, so you will be hitching rides. Speed week gets over 1000 people, so the resources of MtIve are heavily taxed.”

And another reason, apart from lack of wind, why they didn’t try in March.

Probably best not to be there at speed week with your big sailing thing. GA doesn't seem like the kinda guy who laps up the limelight either.

Go hard GA, shiny side up!!

Provided there’s sufficient wind it comes down to drag vs. lateral resistance. The aero drag is 44% greater at 240 than at 200.
Actually, drag is related to AWS, not SOG. So at 30 knots TWS, AWS respectively is near enough to 270 and 230. When you square those, it means a 38% increase in drag. Still a big jump.

PS:


So Horonuku is designed to do at least 250 km/hr……

yeah, I think Horonuku is built with a little bit more professional qualifications and processes. Can probably have a higher level of confidence in the craft.

Taking nothing away from the Iron duck guys who set the previous previous record, but it does look a bit basic garage vibe. From that youtube vid.

Interesting comments from Lenny in this, Sail-World article:

'It was the most positive session for the Land speed team so far, not yet about timing or clocking official records but identifying obvious elements that can be improved to increase performance to be able to achieve the best speeds possible'.

“The steering was tough work,” explained Ashby. “There is constantly a lot of load on the steering so this is the main focus to identify solutions to lighten that load as this will help with performance. From 90-95 true wind angle, which is where I am building vital speed it was really heavy but as soon as I bear away though, the steering wheel is neutralised and unloaded and goes very light and floaty. So to be able to build speed more efficiently and effortlessly will help in reaching higher speeds before the bear away.”

^ nice, had to backtrack to find the article, the link is to a picture SBD.
I saw a big high heading over the area in a couple days, hopefully generates the wind.
