Have fun!
Foresail and keel is added, it improved steering a lot.
Files for the clip-on-keel added...
The boat hull have to be printed with very low infill for low weight. I used 6% Infill.
I made the hull out of PETG and the other parts out of PLA and sprayed the hull with clearcoat for water tightness.
The pipes are 6mm and 10mm carbon fiber pipes and the connection between thr rudder and the rudder arm is made of 3mm cfk pipe just as the steering rods to the servos.
I use ball bearings for the main beam and a knurled nut for the beam adjustment.
The hinges at the beam suspention are made with 4mm teflon tube.
