I rely on board rudders to create most of lateral resistance, hence the main hill is relatively shallow with flattish bottom. Originally the boat has had lots of ideas I tried to test. Some of them proven to be difficult to implement or not functioning as designed. The stubby outrigger is from that era and it needs to be replaced with a long and skinny one. I tried to build a boat which has a shallow draft(success), very maneuverable (satisfactory), and very light (acceptable). I also was hoping that in any wind above 4 knots I would be able to drive the outrigger in planning mode. That I can’t archive reliably in all conditions and I’m planning to build a new outrigger over the winter, although I may start building a new boat from the scratch, knowing what I know already.

Thanks yeah. The boat likes going to weather.

Да проект не завершен. Нужно построить новый аутригер. У меня есть идеи, как сделать управление еще проще, собираюсь построить вторую проа, в которой думаю воплотить новые идеи. Вообщем, нет, планов продвигать проект нет. Проа - это поиск, каждый должен пройти своим путем :)

I went out testing my F27 after repairs. I crashed the boat last year in Race To Alaska.i just got it floating again.

I built the boat to participate in Watertribe events. Sailing in very shallow waters are part of challenges. So rudders are designed to kick up/absorb a hit. It is impossible to do with Newick/Brown/Harris designs.

@@VladimirUD very sensible. Russ Brown says he had never hit anything in his travels…would I be so lucky

It is slow but it is safe unlike gybing in heavy weather. Yes in light to moderate winds sailing by lee totally possible and I have done it a lot. The volume of outrigger is limiting factor and I’m going to build a bigger ama.

@@VladimirUD ok, but jybing a catamaran is not usually an issue

@@markthomasson5077 well, I’m not arguing that a proa is a better boat:). But it has its advantages. No need to jump around to keep a boat sailing is one :)

@@VladimirUD not going into irons as you tack and getting pushed onto a lee shore is another…don’t ask me how I know! ps, I would love to build a proa. I did have a 16’ v hull one once, lots of fun, but not much control

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.

Это только по вашему она никуда не годится. :)

Thank you, Skip. In GoPro editing app called “Quik” (comes with the camera) you can add so called “stickers” to a video. There are stickers for speed and for gps track. If you shoot video with a phone there are several video auditing apps allowing to add data to a video too.

@@VladimirUD Thanks, now I just have to finish the boat.

Обожаю сумасшедших комментаторов за безумные комментарии :)!

No it isn’t possible on my boat, I have stayed mast and the sail wouldn’t pass the stay. It is possible to design such a boat but it would be called tacking outrigger canoe.

Ok thanks

The boat was built for Watertribe events. They have very strict rules about reefing. So yes the mainsail have more reef points. I sailed the boat in 30+ knots of wind….

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.

Спасибо! Ну, может, когда и допилят…

Doesn’t it look like a falling leaf? Beautiful. Thanks for watching!

It was easy. The main hull is sealed, the paddling foot wells are self draining, so she doesn’t ship any water.

Well, once the boat out in clear water it goes in straight line without any input. It actually can be set to self steer.

Yep! :D

The kid is actually accomplished sailor already. Proa or no proa, she is great!

The "eventually" got me, hah!

Thera are a few things, by design, to make it easier. One is the light outrigger. Another one is high volume sealed mast acting as a float. And the third one is the mast stepped on main hull and tilted to leeward. It prevents the boat from passing the “outrigger straight up” point. It is very stable on its side and it has no tendency to turtle, unlike Hobie 16… The only problem is the need to stay attached to the boat, it can get blown away faster than I can swim…

На самом деле, она груженная еще легче ставится, так как все пакуется в основной корпус:)

The boat’s vertical clearance is 25 ft.

Yes, it is. And it has 125 sq ft area.

@@VladimirUD That is a lot of sail area for a very light boat. This has to be fest and fun. How long is LOA?

@@lesp315 Main hull is 18 ft long. She is surprisingly well behaving boat.

Glad you like it! I don’t have plans. There are lots of things o would do differently now. So consider the boat being an inspiration and not the instruction of how to do it:)

She shunts through 90 degrees. She is ok going downwind but she whould definitely benefit from a longer outrigger. It is something I’m planning to build eventually. Too many boats too little time…

@@VladimirUD Thank you for reply. She is beautiful and clever boat. I have a couple of dinghies and now I'm thinking about a canoe. I would like to use it to sail up the California coast. I live in San Diego. Have fun with your toys.

@@lesp315glad you liked the boat! Have fun sailing!

@@VladimirUD I saw you on the another video sailing by a trimaran at the Everglades Challenge. Was that fun?

@@lesp315I have finished Everglades Challenge in several different boats before. So I actually built this proa for the challenge. Very shallow draft and high maneuverability were design parameters. There are several things I would do differently now, but overall the boat turned out to be up to the task :)

Well, as you see I can reliably tack through 90 degrees. So 45 degrees to true wind. I can sail a bit higher but speed drops dramatically. Here is another video of me working upwind ua-cam.com/video/gYwC8ETMIik/v-deo.htmlsi=Z3ydhhQ_-DJ4JNp2

Thank you! Shunting the boat is easy. You can see the rudder lock in another video on the channel. “Crazy Proa project. Steering system” ua-cam.com/video/39JlbHJr7rU/v-deo.htmlsi=w4MTUmh3L_6ogjhT

Площадь погруженной части шверта 0.8x0.24 = 0.19 кв. метра Удлинение 3.3, площадь паруса 11.4 кв метра, площадь проекции погруженной части основного корпуса 5.5x0.1/2 = 0.28 кв.м. Передний шверт работает в диапазоне от 3/4 погруженной части до 1/4 при курсе бейдевинд, в зависимости от условий и силы ветра… То есть суммарная погруженная часть швертов в средних условиях 0.19+0.09 = 0.28 кв метров. Суммарная погруженная площадь, работающая на создание бокового сопротивления (корпус и оба шверта) 0.28+0.28=0.56 кв.м, или 5% от парусности.

I’m glad you liked the boat. I designed the boat with help of my friends and I built it from a scratch. There are no building plans available.

Do you mean daggerboard? Yes, the boat has very efficient high aspect foils. It points as well as any racing dinghy.

Thanks. I made all parts for the rudders system. I either fabricated them from a scratch or I used premade carbon fiber plates and tubes. Plates and tubes are available from several sources. Such as DragonPlate, RockWestComposites or Amazon.

The main hull has flattish bottom with round chines. majority of lateral resistance necessary to sail upwind comes from the boards(rudders). To do so I need to match center of lateral resistance (summary of centers of boards) to center of effort (center of sail area). So I need to readjust rudders at every shunt. If I don’t do so, the boat will round up and stall.

Thank you. The mast is not standing on the main hull. It sits of a strut about a foot off the hull. So the geometry of stays and loads on the mast is not any different than on a wide multihull. Look up the video where I talk about sail rig on my channel.
