Apparently these mini dehumidifiers do help!
Though there was not enough support at the back on the boat and more weight was held by the keel causing floor bending and even not closing the fridge lid properly... All resolved now.
Also drill charger stopped working. Heat exchanger bolt snapped. Faucet's rubber rings shrinked and made it leak. 220V inverter took it's last breath.
New books arrived and solar charger was replaced with configurable MPPT one to avoid AGM batteries overcharge on float mode.
TODO list hasn't decreased but plenty of time to plan for the next visit :)
