On September 1st, we launched the hull in Aughinish bay, without sails, rudder or electronics. The purpose was to see how the hull performed in open water, with the keel attached. As the keel wasn’t properly attached or sealed in place, the main compartment flooded with water, but as the compartments are individually water-tight, this wasn’t an issue. It did lower the boat in the water somewhat, but not to any significant degree.
As the compartment wiring wasn’t completed, and the deck panels weren’t glassed in place, they were attached to the hull using duct tape. Not pretty, but it works.
