nice video! :D thank you for sharing your faults.. also nice DNA ;) (since they where called this at the beginning, never mind) But what software did you use for "generating" the video? (map and speed overlay are nice)
I use GoPro (7 in this case, with extended waterproof battery for 4+ hour recording). Especially the newer ones (9 and 10) have great video stabilization, but no extended battery. For the overlays I used RaceRender in this video, but recently i switched to Telemetry Overlay that you can see in latest video. GPS is taken either from GoPro when mounted statically, or in case of flying mounts, I use GPS data from Sailmon MAX synced with the video.
yes. that boat has only 75kg and everything is constructed for lightness and aero. but to be fair, in this video I broke my 3D printed hinge, which is less rigid than the original carbon hinge (what i broke last year 8-).
@@flyinggorilla, Thank you for the reply. I did have a question I meant to ask before: Does the boat point well(close haul) without a jib? I remember sailing a catamaran without a jib and I could not get as close to the wind. Thanks
@@evvignes it points perfectly upwind. when i sail yardstick club races against melges, j70, brenta 30, musto skiff, tornado...., i can go as high as all the other boats. maybe here or then i sacrifice one or the other degree in height for speed. trying to optimize vmg. the key bummer is in light winds of 2-6kn going downwind with the lack of a gennaker. then the a-cat is slower downwind then all the other beforementioned boat classes that pull out their extra 10-50 squaremeters of sail. with more winds you fly or foil the A-Cat downwind. If you foil you rock!
2 x Cardinal sailing rules not followed, never ever wrap a ‘sheet’ in this case a ‘main sheet’ around the hand, a trap for beginners, obviously if it’s wrapped around the hand the sheet cannot be thrown off instantly, secondly, never allow yourself to fall onto the Mainsail!!!! whilst capsizing, by doing so can be very expensive!!!!, mainsail damage, mast, rigging it’s endless.
A-Class sailing is a bit different, so not every "general sailing rule" fits every boat class and situation. Agreed on the rule not falling into the sail, so sliding along the tramp underneith the boom is preferred. jumping to the other sides where the foils are may be a risk of losing the boat. as to not wrapping the sheet around the hand, yes, completely agreed for for boats heavier than a moth or A-Cat. As a general rule especially on heavier boats you should avoid it. There had been an incident on Nacra 17 where the helmsman had wrapped the traveler control line around his hand and lost 3 fingers in a capsize (www.sail-world.com/Australia/Bora-Gulari-injured-in-training-accident-prior-to-Nacra-17-Worlds/-156851?source=google) . Nacra 17 weighs 171kg + crew. An A-Cat is 75kg light and built for one person sailing, so much lower risk. And on the foiling A-Cat you have almost no other choice than wrapping the mainsheet, especially when balancing the boat on the foils, the mainsheet needs to be worked hard. When you watch worlds #1 on A-Cat foiling Mischa Heemskerk you will see him wrapping the mainsheet around his hand too (see czcams.com/video/0RMf8PlS1GM/video.html and czcams.com/video/vh6n0RSoOio/video.html as an example), because when foiling in the trapeze you have to react so quickly and there is no time to hand over the mainsheet to the tillerhand and regrab it (unless for preparing for a tack/jybe). Finally, also as recommended in the Nacra report mentioned before, I do wear cut-protected gloves and not the regular thin gloves. While those dont provide any guarantee when wrapping, they may help, at least in cases when hands hit foils or shrouds hard. In case there is a technique on the A-Cat on how to achieve the same sheeting agility with one hand only without wrapping, let me know.
Fast boat! ...Gotta have the bad days to appreciate the good ones!
Forgetting to hook the trapeeze - classic :-) Too bad the tiller extension broke. Great video.
Did that on my taipan last season, missed the trap, went for a swim, broke the tiller extension... Was a dnf..
Dude I've totally forgot to hook in before and just fell off the boat just like that lol
Always interesting videos ;)
Nice video!

thanks. I use these days TelemetryOverlay for that purpose. goprotelemetryextractor.com/telemetry-overlay-gps-video-sensors
I really liked the gps data over the video, what kind of camera do you use?

Wow, that boat is fragile. I guess that’s not unusual for high performance craft.

The main sheet is designed to be let out as well as tightening. This is painful to watch
Wow! Fun to watch! Reminds me of the old days, raced 18◻'s, don't think they exist now. I had a Nacra.
