Crazy_Proa project, Shunting out of narrow creek in light and shifty winds

- I added two speed sheeting system and boom limiter(pusher) to prevent it to go up while shunting or going downwind. Things work much smoother now...

Great Vid man, best Shunting I seen on the tube!!! Amazing! First time I see the advantage of Aft CE on shunter. My rig carries CE ahead of mid ship, yours Aft. I must go off the wind, sail on a beam reach, some times slow, sometimes I may almost stop, now I shunt and move my rig to my new bow, boat heads up and off I go, sailing to windward....
Your boat turns around it's sail, like a wind vane, Amazing!! I lose distance sailing towards a hazard on a beam reach, you shunt like a tacker losing nothing! turning the vessel around your sail, Well Done!!!
Keep Shunting Bro,

Thanks, man. That was the idea. I always thought that I can make a proa which would shunt without loosing forward momentum. I almost there. Thinking about building second proa which will shunt on a spot.
I've done this on a bigger proa and it's really not that much different than tacking once you get the hang of it. Sailing right up to the rocks and coming to a complete stop within a boat length and then shooting off in the other direction again is a unique experience
Thanks I always wanted to see a video of a proa shunting up a narrow channel. Interesting that using both rudders worked so well, though it would take a bit of concentration to get it right.
Totally get the name Crazy Proa. I like the lazy man's shunting style.
Охренеть! Никогда не думал что он может и передом и задом. А разворачивается-то как почти на месте)).
Да Владимир может делать вещи!!!
Short-shunting zen. This is inspiring. Thanks.
My pleasure!
Обожаю сумасшедших конструкторов за оригинальность !
Обожаю сумасшедших комментаторов за безумные комментарии :)!
looks like it's going great! I've never seen a proa with the rudders right on the very ends like that!
wouldn't mind a close up view of how they work!
I’m planning to do walk around video with an explanation of all system as soon as I finish active “try, break and fix” phase.
How clever is that! Interesting and wierd looking.
Doesn’t it look like a falling leaf? Beautiful.
Thanks for watching!
Thank you, have an idea of how I want to build a Proa, this gave me an idea about the sail, great! 🙂
Grad to be of use! I just want to point out that the type of unirig I use will not work well on classic deep V asymmetric proa hull. I use adjustable-on-a-fly deep boards to bring the center of lateral resistance where I want it to be.
Excellent…but did you also try tacking to compare. (If that is possible)
I have to problem to shunt out of any small place but it is slower than tacking. Kids outperform me on dinghies going out of the cove.
wow it really picks up speed when it gets out into the channel!
The boat is fast. I clocked 7 knots going upwind in 10 to 12 knots of wind.
@@VladimirUD what is the sail from?

well done! did you use the rudders or was it just sail position? it‘s impressive either way, i‘m just curious about the design and possibilities
There are rudders on bows. I can steer with both in light conditions. However normally front rudder locks and becomes a daggerboard. I can lift or lower boards remotely from about anywhere on the boat to adjust lateral resistance.
So as long as I’m on a straight course, handling of the Crazy_Proa isn’t any different than any performance boat, I steer with rear rudder. While shunting I can swing the boat around on a spot steering with both rudders.
very interesting design, thanks for video and info
@@VladimirUDis there also a centreboard. I am surprised you need any forward rudder acting as a centre board at all with the sail pressure aft.
..sure shows up all those folk obsessed with traditional proas how to do it. (Though they have their place)
She does seem to point remarkably high.
There should be a significant force on a rudder, right? Center of lateral resistance is constant, but the sail force goes around the mast while you tacking 🤔
Light winds in the video. In normal windy conditions I can adjust center of lateral resistance by locking front rudder, it becomes bow daggerboard and raising it about 2/3 up. So basically I always can shift center of lateral resistance anywhere I want(or need) by raising or lowering boards. I actually can steer the boat with both rudders locked and by just raising and lowering the front one just a bit.
@@VladimirUD you good!
Handsome!
What are the specifications? Length, weight, sail area?
Cheers!
Main hull 18 ft. Outrigger 8 ft. Width 8.2?(I need to measure, I was reducing it from the original build) Weight is under 175 lbs. I need to weight it but I built it to 140 lbs and now I slowly adding weight with all the reinforcements,
Sail area 130 sq ft sail plus mast.
Mast is 23 ft. Draft with boards up is 5 inches. Draft with boards down 3 ft.
@@VladimirUD Thank you very much!
It's a great project!

Can we get the measurements in cubits?
