Today the first half of the hull mold got planked using about 60 of the basswood strips we cut earlier. It seems like we have cut just enough to finish the other half and the inner deck. It took another full day to complete the planking and create epoxy fillets on the inside that hold everything…

The CNC work is done and we are moving to our final workshop.  

Finally getting started with the actual building process… it was nice to see the design we have been working on for such a long time turning into something real!

Cutting a few sheets of basswood veneer into 900 m of strips on a bandsaw…  

An optimization of the hulls stability and self righting ability was carried out using CAESES. The goal was to improve upright stability and maximum righting arm of the hull while keeping it’s self righting ability. 2100 different designs were evaluated using an algorithm to find the one suiting our needs best. More detailed information on the process…

Just picked up our ducted propeller at the customs. It is a T100 made by Blue Robotics and will serve us as a temporary propulsion system to test all of our hardware and get the autopilot and gps tracking running. Later on we are planning to design our own propulsion unit wich shall be less prone to getting…

In order to prevent the boat from slipping sideways in case of sidewinds and providing a center of rotation to improve maneuverability it was decided to add a small keel. This decision also adds a few other benefits: Although the selfrighting ability of the hull doesn’t inevitably require a weighted keel, we will probably take…
