> The initial fabrication of the boat is complete and I have started a series of commissioning test. She has been in the water for the initial tea bag test. For the last 6 months I have been building a house with me son so have not done any further work on the boat. I hope to be back on the test program after my son and family have moved into their new house. Initial test confirmed basic buoyancy states and hull/hatch integrity and identified a bad solenoid valve.
