Re: Konzept/Bau einer hochseetüchtigen 12 m Fahrtenproa
Verfasst: Sa 12. Dez 2015, 07:18Hallo Reto,
immer mit der Ruhe, ich wollte hier erst einmal überhaupt auf die Website hinweisen. Manfred wird sicher über die Feiertage seine Informationen updaten, hat er zumindest gesagt. Der Mast ist inzwischen verstärkt und steht einwandfrei.

Hier einstweilen ein Auszug aus dem Text für das proa_file:
When sailing I am always impressed by the course stability. I remember one trip when I did not touch the tiller for more than one hour. Further more it is incredible how quit and calm this boat is behaving. On one of the photos you see a post card. I put it there at the beginning of the season and it did not fall over during the whole summer and under all weather conditions.
The boat leads to a lot of new contacts. If you are not communicative from nature, you will become it with this boat. Almost always people stand in front of the boat and ask what this exotic thing may be and how all the features may work. One time a couple came across the whole harbour. They first saw only the strange form of the A-mast in the forest of masts. They could not imagine what this could be but in any way it must have been very exciting. So they walked through the whole harbour.
Another time a sailor asked us when we would leave. He wanted to follow us to see the boat in action and take some pictures.
Right from the beginning of the project it was clear that shunting would mean some effort. You have to roll up the genoa then to turn around the main, to lift the first rudder, to lower the second rudder and to roll out the second genoa. At the moment this manoeuver takes almost 1 minute. With two well skilled people I guess it might be possible to come down to 30 sec. But still it is not comparable to the tack of a monohull. Especially when you take into consideration that the boat stopps. So sailing in narrow waters will not become the preferred trip with this boat (which is not a real surprise). That is a pity because there are some nice sounds around the home port Boltenhagen in the southern baltic.
In light winds the speed is quite considerable. I measured 4,4 - 5,6 kn at 1,8 - 3,1 kn true wind. At 5-6 kn true wind the speed was between 6 and 9,3 kn. All this data were taken on a course close to the wind. But because of the relatively high speed this means 90 degrees to the true wind.
