OHANDA ONE
We need truly international criss-cross disciplinary art&science safe havens for celebrating and fostering curiosity in the scale that can make a difference. We have CERN on land ISS in space. Ohanda One will pilot a fleet of sea vessels, capable of crossing the ocean, gathering 100+ curious minds at a time for research and prototype on their topics of choice. Ohanda One is about open science, open software & hardware, open data and formats. It aims to be emission-free in the first five years of sail. Onboard, each individual will be a part of greater collaborative team, and besides their own topics, work together towards the sustainability goals. We work together, we make food and eat together, we relax together. There are no passengers.
“The impossible missions are the only ones which succeed.”

Shiplet Launching Ceremony
Even though it is a bit hard to tell when exactly we’ll feel ready for it, there will be a hilarious get-together around the official launching of the first [(fully)] functional 1:100 scale model prototype of OHANDA ONE – aka the shiplet. We plan to welcome everyone who wants to join at a waterfront in[…]
AHOD I – All Hands On Deck!
Preparing for a simulation / summer camp for an enacted journey on Ohanda One 2025 Ohanda.One is a long-term utopian science fiction (project) played out by an international, transdisciplinary group of Open Knowledge Enthusiast, designing, building and operating a futuristic zero emission ocean vessel. The vessel will host about 150 to 200 people for traveling[…]
Pressure Contra Ultrasonic Turmoils
A good lesson about failures of theoretical design and learning from practical research findings is when we observe that the shiplet won’t plunge when test-driving in open waters. After checking the software and many other possible reasons, it turns out the depth meter does not work. But it only fails when driving, what made it[…]
History Repeating?
In April 1875 Sir Henry Bessemer launched the Bessemer Saloon Ship, an experimental Victorian cross-channel passenger paddle steamer, intended to combat seasickness with a swinging cabin, a concept devised by the engineer and inventor that he patented in December 1869. The cabin was designed to pivot independently of the ship’s hull, suspended on a system[…]
Good to go?!
After 7 years of prototyping it feels almost a bit unreal when we suddenly start wondering what actually still needs to be done before the shiplet’s first test run on open waters. Besides continuous iterations of optimizing the code it looks like there is not so much left to do at the moment. Are we[…]
Cybernetic Marine Mechatronics
Our vision of a “sailing submarine” aka a sailing ship with a submerged hull requires a set of sensors and actuators to compensate the absence of stabilizing buoyancy, caused by minimizing the ship’s volume near the water surface. While the design is supposed to reduce the response to sea state and minimizes the stalling bow[…]
Balloon Blast
In free-style scale model prototyping one can daydream into that microcosm, where you can do miraculous pointy-headed things you could never do in full size reality. A good example for this is to use air balloons from the jamboree store to level and balance the shiplet’s position and mass distribution inside the tubular ballast tanks.[…]
Sviveling Static Sails
Inspired by the DynaRig, designed in the 1960s by the German engineer Wilhelm Prölß, we decided to equip the shiplet with likewise sviveling, but static sails. We will use radio controlled servos to manually rotate the konvex profiles within our pivoted mast supports, also to test detrimental positions and situations. To start with, we use some[…]
Colorful High Hydrostatic Hopes
Finally the shiplet got painted. Sincere thanks are given to Cadus for providing the space for the paint job and to Tuomo for providing the coloration. Now we are of course really eager, ney, we are thrilled, excited, super curious, on tenterhooks, … (!!!) to find out, if all our calculations and estimations about downforces[…]
