FIRST TOWING TANK TESTS
Right after the exhibition in Den Helder the little Windfinder traveled south for a completely different adventure: Here is the scale model of the Roaring Forties Windfinder in the towing tank at TU Delft!
This first test campaign was purely about the hull, without windmill and propeller. We towed the boat with different ballast at different speeds to measure hull resistance. Below you see the equivalent of 7 knots, with half a kilo extra ballast.
The resistance data are needed for wind tunnel tests later this winter for improvements of the headwind propulsion system. Windmill, propeller and hull have to match perfectly. Until now, with the older Windfinders, I have always done that with trial and error, a lot of real size testing on the ocean with adjustable pitch windmills, so I do have an idea of what works and what not. But of course, that can be optimized! That's what I'm going to do the coming months.
Many many thanks to the towing tank people in Delft!

Vrijdag 3 mei 2019, 14 - 15:00 uur
Nederlands gesproken; voor mensen vanaf tien jaar
15 jaar Windvinder! Wipke Iwersen vertelt hoe het begon en waar het naartoe gaat: van de Oer-Windvinder en zijn groeiende familie van nakomelingen in de noordoostpassaat op de Stille Oceaan, tot het nieuwste Windvinder bouwproject - een speciaalschip voor een tegenwindexpeditie rond Antarctica...
De grootste en meest zeewaardige van alle tot nu toe bekende Windvinders, wordt dit de ultieme stormversie. De eerste zelfrichtende Windvinder! Een schip dat kapseist en weer opstaat - gemaakt voor een reis tussen ijsbergen en enorme brekende golven... gestuurd en aangedreven, zoals het hoort, door niets dan tegenwind. Hoe moet zo'n schip eruit zien?
Kom kijken! Wipke Iwersen laat nooit eerder getoonde actuele foto's zien van ontwikkeling en bouw van de nieuwe prototype. De prototype wordt in de komende maanden in Nederland getest. Daarna gaan we het levensgrote schip bouwen. Misschien wil je wel meedoen?

SEPTEMBER / OCTOBER 2016:
FINDING WIND ON THE NORTH ATLANTIC
I left Thor and the family of Windfinders alone for a while to help FAIRTRANSPORT in an urgent operation to sail the Tres Hombres home across the North Atlantic, from Canada to the Netherlands.
The schoonerbrig Tres HombresTres Hombres
It was the second half of September; there was no time to lose. We went to Nova Scotia with an international emergency crew and Captain Arjen van der Veen (one of the original Tres Hombres), to relieve the old crew and bring the ship home. The cook and some of the trainees were still on board - and the precious cargo of rum, molasses, coffee and cacao. We borrowed some more salty sailors from tall-ship Picton Castle and Viking long boat Draken, and were ready to go.
What a phantastic challenge for a Windfinder! North Atlantic crossing with an engineless sailing vessel between hurricane season and autumn storms...
We would bring the ship home WHATEVER would happen.

Windfinder Workshop - July 2016
BREST 2016
One thousand participating ships ... so many wonderful things to do and to see!
We built a beautiful three meter model of a simple Windfinder - two light and flexible skin-on-frame hulls and a windmill drive with eight sails. Unfortunately, when the thing was ready to be launched, there was no wind, just no wind at all! So the experiments in the water are postponed to the next nice opportunity.
Anyway - we had a great time, met fantastic people, and built a wonderful thing that's waiting for the autumn storms. Many thanks to everybody who helped with lashings and sewing sails - and very special thanks to Jerry and Erik for all your help the whole week!
Thanks to the Embassy of the Netherlands for inviting Project Windvinder to the festival - and thanks to tugboat "Elbe" and her wonderful crew for the lift from Rotterdam to Brest (for me and all the building material), and tall ship "De Gallant" for the lift back from Brest to Amsterdam, for me and the little Windfinder...
BREST 2016
13 - 19 July
Join us in Brest!
6-DAYWINDFINDER WORKSHOP "HOW TO TURN HEADWIND INTO PROPULSION"
By order of the Embassy of the Netherlands, a 3 meter model of a basic headwind-driven Windfinder will be built and launched at the maritime festival Brest 2016
- come with us and meet them in person!
Join us for a part of our Pacific expedition (sail with us) to help developing the fleet of real size, oceangoing headwind-driven vessels, or join one of our shorter workshops in harbors of Europe and America, to build and test smaller working models of the ocean versions. The models become part of the traveling Windfinder exhibition.

2014: WINDVINDER MEMBER OF THE INTERNATIONAL WINDSHIP ASSOCIATION
INTERNATIONAL WINDSHIP ASSOCIATION LAUNCHED
An international association has been created to facilitate and promote
wind propulsion for commercial shipping worldwide.
all industry stakeholders, experts, academics and NGO supporters in the development of a windship sector to shape industry and government attitudes and policies.
The objectives of IWSA include:
- create a clear sectoral approach, grouping like-minded organisations and individuals that can share ideas, skills, as well as technical and market information for the development of commercial wind-ships.
- assist in securing funding streams, project collaboration, grant applications, research and the pooling of resources.
- act as a central information hub for the wind propulsion sector, ship owners and operators, shipyards, ports, governments, equipment producers, the media, NGOs, and the general public.
