    That would be the 24ft Strider....

    Bear off or luff up; its easier to control a luff - bec all sails are depowered without doing anything but turn the rudder. In a bear off with flying hull - on the edge - if sails are not eased perfectly it can easy tip over. The heeling moment will not be so big in a luff bec that is usually not many degrees - in a bear off it can help - but the windforce will easy counter it.

    Seems like interesting story about stuck at sea in Covid.... I will read it later.

    Mr. Oudrup is a serious sailor - he didnt cheat with motor thats for sure. He has also sailed regatta in heavy winds in Denmark where he beat a 40+ X-boat on a upwind leg. Often you see these type of boats with sail that is totally useless - but they have strong rigs that can handle better and bigger sails. And if you are abit concerned about weight and keep the boat klean with saildrives - they can be made sailing if you want too.

    well - I suppose reefing is allowed if you dont want to hold the sheet. Its only when you really start to lift the windward hull you need to holdt the sheets. Fast and lights as it is - it will go fast event with conservative reefing and big safety margins.

    I will see the interviews - but just on how slow the Lagoon 380 is - ask Lars Oudrup - the designer of the Havkatt boats of Denmark he retired in one and sailed the world and ARC and did pretty well there some years ago - so if the boat get a good set of sail and dedicated skipper some can get surprised.

    As I mentioned before - kiting would suit a symmetric proa very well. Its hard to see a tack with a kite on a boat - maybe it could be done with ballast. On a bord that weights next to nothing and where the sailor/kite totally dominate the energy its perfect. Downwind with a kite jibbing would be better - on a boat....

    To get 3m arm the boat has to heel 20deg - when its level - its nothing. When you lift out the ama its less than 0,5m arm (6,7m c-c) - so not a big thing.10kg in the ama would counter it - or a person moves slightly out. Using water ballast is interesting shorthanded. The thing with a tacking proa is that it is different - stable as atlantic and exiting as pacific. The pacific side - the crew can move out - and it can be sailed on just the main hull in light condition - making it the fastest on the water. The rig can be smaller bec it can use a bowsprit - a very cheap and effective way of getting more sail-area when needed (you always need more in the light). Ok foils can be two directional - but one is better, and two foils in the end - how is that working compare to a dagger in the optimal place? Me build a proa? Well I have an idea of a light recreating wessel that can be transported on a car-roof - a proa like Waa Motu - but smaller - could be a fun project, but I would do the design myself. No need for books when you have internet.

    Yes this is really cool....

    Nice boats that is linked over - makes a lot sense. Vikingships and traditions boats - yes many are double enders - using planks it makes sense - also bec they dont sail faster that the following seas and have to have a solution for that. Vikings - like the people in the pacific used streering-oar - not rudders - they had no daggers either and didnt know how a good foil should be shaped. Yes Farrier has double end amas - he had a reason for that - a SC30 has a "longer" amas that is cut - and its a lot faster. Im from the region of Oseberg and Gokstad - some years ago we met the Oseberg replika on its first sailtest with the yellow tri. And I followed the building of it - very impressive from logs to vikingship using basically an axe. I have nothing to do with Harryproa. The argument og one big hull is a good - and I have experienced that a trimaran has some issues with slamming hulls and motion in seas. Many foils; its ok - a tacking proa could have good use of two rudders and even two daggers - the problem is when a rudder or dagger has to work both ways - then it gets complicated. Same with the rig.

    Pro-people are very sensitive - but its very hard to get some facts. Downvote what you want. The basic idea of proa I got after a while - but I can not see the point in shunting and symmetric ends. But there a solution to that - why isnt this popular - is it dogmatism?

    Of course you add a pod - but bow and stern and tacking - atlantic on one tack and pacific on the other. To sum up: Tacking/jibbing is better than shunting. To have a bow and stern is better than symmetric - can have more space and a "longer" hull for the same lengt. Just one dagger and one rudder - no need to double up or change place. Simpler and easier to use. Rigging - unstayed and you have the same advantages as other proas. Very light and cheap - one main hull and one ama. Better for motor.

    Scale up to 35ft - why would it be more prone to capsize than a pacific proa?

    And why isnt this a good idea?

    I think its rather big difference here; 40ft ocean going powerful trimaran with - see the vid. very easy 20+ knots - no effort - can take the payload that trip needs - so its the right thing to use. But it was listed at 280.000USD.
