Scored a great marine dehumidifier on eBay – Dry-Pal 1 by Mermaid.
My friend Viktar joined me again for a fun workday. While I built a shelf in the stern section (just behind/above the battery bank), Viktar hardwired the unit into the AC panel, rewired the control panel and extended its cord so it could be mounted on the interior.
Next steps are to run ducts and 3D print adapters for intake.
