Ok team, here goes my first blog post. My goal here is to build a Digital Flight Control System (DFCS) for my UFO using a sonar range sensor as opposed to the wand. The design needs to completely mimic the performance of the wand system currently in the boat. The system needs to be fully removable to allow for One Design Racing if desired.
A few design guidelines...
Improvements to current control system:
1) Sensing wave terrain out ahead of the boat
2) Not engaging the mainfoil flap until the boatspeed hits 7 knots to reduce drag while floating
3) Toggle settings for upwind vs. downwind (maybe a button press?)
4) Data acquisition
5) Auto rear foil rake adjustment (this is a maybe feature, this would be lots of extra hardware for limited improvement)
Questions to answer:
1) Do I need a GPS to get good boat speed or is the accel, gyro, magnetometer IMS good enough?
2) How and where will I couple the servo to the flap control push rod
3) How big a challenge will marinization be? Is enough to buy waterproof parts and a waterproof box?
4) Is it useful to have more than two sonar sensors to create an accurate map of oncoming wave motion? Does wave motion traveling orthogonal to the direction of the boat matter? Or are waves going so slow compared to the speed of the boat that it doesn't matter?
I will endeavour to use parts that have excellent tutorials available online.
I will be concerned about the cost of my time even when it costs a bit more money to buy parts that are easier to integrate.

I am entertaining offers for my boat.
3200 lbs of fast 26' boat. We win enough for it to be routine when we go out.

It is getting just too hard for me as a disabled person to maintain and sail the boat. Plus I am not getting any younger.
After a stupendous summer of sailing/cruising, we're back to find there's a HUGE security breach in Google Android, affecting Samsung S9, Huawei P10, LG G6 and Sony Xperia XZ Premium phones (one of which I own).

Sometimes we wonder why we bother making land, with all this junk going on. But we persevere.
Today's mini-happy was getting a Top Tweet rating on my @AussiGigi feed. More than I ever get here, huh, @Zapata?
Someone from SA asked offline why aft deck photos keep showing up on my Background, and how long we've been following ocean racing. A little while, I said, ever since we retired from fighting the tides. As for the wide beams...
"A team would need between NZ$145m–217m to be in the hunt to claim the Auld Mug." —Dennis Conner
"As much as Team France would like to contest the next America's Cup, without a war chest to play with, it's unlikely they will be able to mount a challenge.
The French outfit lost its naming rights sponsor Groupama earlier this year and have been unable to find a replacement ahead of the December 31 deadline of late entries for the 2021 regatta in Auckland.
Skipper Franck Cammas told the Herald his team want to be competitive, and will give themselves until the beginning of December to work out if they will be able to do that or not.
'We are still in contact with prospects so we will communicate that, but for now we are not going on but we have one month to go or not to go and we want to work until the end of November for that....
'For now I don't know at all [to be a possible team member of another Italian syndicate entering the 36th AC or not] because I'm now focused on Team France and I never try to open the door to go with another team.
'For now the problem is if we have money to go; how can we do our best with the lack of time? We have now compared with the other teams, and I think the first goal is to link with a big team to try to be on time for the first race.
'This is more my concern now, then we will see what happens next year.' —Franck Cammas, DongFeng team member, and winner of this year's Volvo Ocean Race

Skimming through my albums this past week, and of course thoughts of 34th America's Cup popped up when this magnificent yacht staircase appeared. Didn't cite the photo. Hoʻoponopono.<sigh> Howzit, Mr. Ellison?
