WIND FRIGATE I
Windschip Project has partnered with Bosgraaf Yacht Design
An important step forward to build a CO2-free freighter: The Windship
Research has shown that, in order to meet the UN Convention to stay below two degrees of global warming, eleven percent of the existing merchant fleet will have to be powered by wind
AMSTERDAM APRIL 15, 2016: Windschip Project is initiated by Ron de Vos. Over the years 2000 to 2014 he wrote three books on the historic development of Dutch sailing ships. It is therefore not surprising that he has developed an innovative CO2-free windship for the merchant navy.
Peter Bosgraaf has been successfully working as an independent ship designer for over 25 years. Being an active sailor on sail- and motorboats, he knows what does and does not work, and he is an acknowledged designer of innovative and comfortable ships. He specializes in durability and light weight constructions.
The collaboration goal is to innovate and to concretize the rigging as well as the hull so when a client wants to build a windship the plan can immediately be worked out.
* Research has shown that if the shipping world will meet IMO requirements (based on the UN Convention to keep global warming below two degrees), 11% of the existing fleet will be powered by wind.

EXAMPLE WIND FRIGATE I
If government plus individual(s)/concern(s) are prepared to launch a Wind Ship, a feasibility study will have to be initiated, solely to accomplish the construction. The Wind Frigate will have to be built as cheaply as possible.
A market research will be needed. This research will only focus on the transport of sustainable products. This study can not be decisive to build a Wind Ship or not. On this moment, both in the freight market and in the financial world, there is so much uncertainty, that a balance in the decision is almost impossible.
Therefore, after the ship is launched, a first reconnaissance trip is needed in order to discover the market conditions.
1. The hull will be built according to the wood core system: wood skin (cedar) on both sides reinforced with fiberglass and epoxy. All the timbers, such as frames, deck beams, stems etc. (Larix) will be laminated.
2. The rig will be composed of hollow wooden masts and support poles (Larix) reinforced with glass-mat and epoxy. The trapezoidal shape of the poles is easy to construct.
3. There are only two types of yards. After preparing a mold from each type the yard is made of one piece from a very light material.
Also, the connection between the mast and the yard will be carried out in laminated wood.
4. Sails: the canvas of square sails, nine large and five small ones, and three staysails, a total of 2.500 m², will be made with a weight between 9 and 12,5 oz.
5. Winches. There are two types of winches to control the sails: sail winches and brace winches.
All winches are operated independently by electric or hydraulic system.
The anchor winch plus anchors are conventional.
6. The mechanical hybrid propulsion. In addition to a main engine, an E-propulsion system will be installed. This is an electric engine and batteries. Besides a generator will be installed on the propeller shaft.
Also, where possible, wind generators and solar cells will be used.
7. Passenger and crew quarters are sober, but must comply with the latest safety rules.
After several trips, shape, material and rig will be looked at.
We will also consider whether the type of vessel is suitable for the market in which it was sailing. What is the best place from where the ship will transport the sustainably grown products? Will the products be delivered as bulk cargo, general cargo or containers? Which is the best cargo for a Wind Ship?
Did the sailing freighter, during his voyage, meet some infrastructural problems? Without doubt, there has to be taken measures in ports to make it possible for a sailing ship with fixed masts to load and unload easily.
The owner(s) of the Wind Ship will assess the transport on sustainability. Perhaps the shipowner can use his influence on the market to transport certain products.
Once inquired all, one wooden mold will be used for building more hulls of the same size and of the cheapest and lightest materials. Also an evaluation of the rig could take place.
