    Completely true Gomboc is just a physics box, it does have some aero hydro models built in but that is lower fidelity data. The teams would need to do their own CFD runs.

    Whatever the case. All the other AC teams are very happy NZ is spending their money and man power on something totally unrelated to winning the cup.

    Had to go back through articles and your right it wasn’t the battery.

    AC40

    AM sunk because a battery wasn't tied down properly or broke the tie down and shot through the hull bottom, different than this. The AC40 broke because they didn't carry the deck beams forward far enough. The deck panel that buckled looks pretty big and flat and is surprising that they stop...

    There are auto dump system like upside up and things like vspar sail vision but haven’t seen anybody make a soft sail control system for wl kinda sailing. Its a really hard problem.

    Asked a guy on base. Main and Jib controls are all hydraulic but i don't know of any system to auto control soft sails (wings are easier to control). So somebody still has to push buttons. Steering is full manual basic cable and quadrant system no fly by wire or actuators. I think its kinda...

    I’m more ok with ap’s on distance races but even ultimes don’t have flight control system that can’t be used during races. (They have them but not class legal). If ultimes judge that’s too far than surely an inshore day racer shouldn’t have full auto flight

    I bet they get the autopilot. It’s all part of Dan’s company zero to sum https://sumtozero.com/products/ Gomboc is the simulator that most teams are using. etnz, lr, am, ineos Blogger is the autopilot that the ac40 most likely uses. From what I’ve heard gomboc is used to help program blogger

    Not really apples to apples. With the laser its weight dependent for rig size. That's why they have laser radials. With these boats and the switch to cyclors it would make it easier than previous boats to include women. There are plenty of strong women into cycling and the rest of the jobs...

    Having youth and womens AC is just a waste of time and money. Just write in the rules that 50% need to be women and two members on the boat have to be 18 or under, done.

    I want a video of what’s it’s like from the perspective of the leeward cockpit in a capsize. Is it as dangerous as it looks or is it fine and he’s just hanging out in his personal pool with a nice sun shade?

    Boat building in general is not green. You end up tossing twice as much in the bin as you put in the boat. Think of all the prepreg plastic backer, consumables, molds, plugs, cutoffs. Adding hydrogen to it doesn’t make a lick of difference. If they modified a 50 year old powerboat with...

    Glen should just pack up and head to the states. The whole southwest US is stuck in a mega drought and it doesn't look like it will change anytime soon
