Swelling
It’s 3 days after launching and Meritaten has almost stopped taking water. I checked today that it still increases in the bilge but at very slow rate so that the pump starts once only during the day. I hope that my repairs have improved the situation and she will become fully dry in the bilge after a week.
As a reference for next years I documented where the leaks occur during launching - and at what scale.
It turns out to be mostly amidships and under the cockpit. Today these leaks are mostly gone so the cause of slow increase in water level must be on the garboard plank.
