New sail TNT 34

Tnt 34

Kris, I'm impressed with your boat and even more impressed with your willingness to publish meaningfull numbers(the more the better)- too few designers do that even though this is a design forum-so thanks.

 

It looks really cool All the best with it
I'm new to the forums so excuse me if I'm out of place here, you say the beam "trailer mode" is 2.9 m. I was under the impression that the maximum width for a car trailer in N.Z. and the U.S. was 2.4 metres, I would have thought it would make more sense to build to standard trailer limits. Which from memory are 11.5M x 2.4M x 4.25M max weight 3500KG

 

The max width for transporting in Europe is 2.65 m , except Italy , where is really 2,5 m , but till 3.05 m You need to buy local permition only . Above 3,05 is special transport required . As a manufacturer of trailerable power cats Motorcat brand ( www.motorcat.com ) , we are living with width problem , so this why we built MC 29 , which beam is 2,65 m. Regarding to US permits it depends to local state law ( see attached ) . Anyway one of MC 30 owners every year trailered His Mc 30 ( 2,98 m ) from MD to FL without any permits or problems. http://mc30deuce.blogspot.com/search?updated-max=2009-05-06T19:35:00-07:00&max-results=7

 

see the movie shows, how the folding of TNT 34 work . Simply and practical , isn`t it ?

 

We posted the movie shows, how the folding of TNT 34 work on Utube and add the second one with a view from the back side .
Simply and practical , isn`t it ?

Missing link

I seem to be missing something- what holds the hulls in the extended (sailing) position? I don't see any water stays or struts. I thought I saw them in the cad drawings, but don't see how/where they attach on the prototype. The boat really looks nice and innovative. B

 

There is wire strut but 2 ft sleeve acts as cantilever to fix the beam and wire will take minimal forces..
Large ORMA tris do not have any struts and TNT 34 simulates this kind of solution by this telescopic /sliding mechanism.Once sleeve is fixed is a solid as "fixed " beam.

 

Motor,

you were asking for suggestions about how to market this boat. I am still unsure what your intended market is. Are you going after people who want a fast boat for themselves, racing, OD racing, cruising, ect... The answer to this will help identify how to market it.

 

This paricular unit is cruiser/racer (to beat DF 35 or F 36 or F 33 X)but with beam of 28 ft and 50 ft mast we can easily have racer /crusier

 

Already in the water? I have received a mail from Italy offering a test drive.

 

Already in bulding progress . First trial for a public early spring in Poland near the shipyard on the Bukowka lake . Just now we have a terrible winter with minus grad celsjus and more than 50 cm snow outside

 

The 10 m float is almost 10 m (32’) long and can be lifted by one person (each side)

 

last drawing

enjoy
