Self-supporting and tidal sail




by Verna » 16/02/08, 10:12

Hello gentlemen,

It should be noted that the following two systems could be applied to this sailboat, or future ones to come:

1 ° / A freestyle sailing concept published on my website:

http://inventions.a.verna.free.fr/voile.htm


2 ° / A concept of tugboat turbine visible here:


http://inventions.a.verna.free.fr/pagehydrolienne.htm

Already offered here:

Sincerely,

Christophe Verna

For sailing it looks like the project Skysails not?

Self-supporting sail




by Verna » 16/02/08, 10:30

Hello,

My system is preferable to that of "Skysails", in that in the event of a drop in the wind, the freestanding wing cannot fall into the water, because it is carried by one or more gases lighter than the air, this avoids the loss of time inherent in the recovery of the waterlogged sail, or its entanglement in the propeller.

On the other hand, the "Skysails" sail is only a large "Kitesurf" type sail.

Have a good day,

Christophe Verna

Hello everyone.
I just registered on this site full of very interesting information and it is with pleasure that I see a subject on CTMV.
Indeed, I am closely involved in this project and I can perhaps provide some answers to your questions.

"Are the docks (still) equipped to be able to unload sailboat freighters?"
The rigging will not interfere with the loading and unloading operations because there will be no balm between the two masts (where the hatch cover is located). In addition, the wines will be transported by pallets and loaded and unloaded using the two on-board loading masts, using the "flying package" technique for those who know.

The speed of the ship to sail will be between 6 and 14 nodes depending on the conditions.
The planned area of ​​navigation (gulf of Gascony and Celtic Sea) is well supplied in terms of winds.
I invite you to consult the modeling of the future sailboat on:
http://www.ctmv.eu/Modelisation.html

Compared to the ton it is impossible that a sailboat is advantageous in terms of human resources ... Unless it is fully automated as the phocea of ​​the other crook of tapie ... and again ...

Once again Janco was right in comparing oil to virtual slaves ... "


The ship will obviously be very automated.
It must be realized that, for a conventional freighter, the cost of the bunkers (fuel) represents between one third and one half of the total cost of exploitation. Salaries are for less than 10%.
The purpose of this venture is to achieve commercial viability, not to build a project that is kept alive by grants.

First of all, Hi Choucane and welcome to forums econology.

Good, to be unpleasant : Mrgreen: , I would start by saying that it is normal that there is no ointment between the two masts (we write "boom" for a sailboat, "balm", it is for cosmetics).

Well then, to be more constructive, on the plans that we see there: http://www.ctmv.eu/carnetbord.html there is a boom on the mast before. It is also more or less essential in this configuration of sail.
On the other hand, nothing prevents staggering the boom from one side or the other for loading / unloading.

Oops! Well done Targol!

Otherwise, the plans you have seen are not the last ones. You can see on the final sketch that the boom has disappeared.
