Re: Condensation inside sailboat...

An installed garboard drain (a keel 'plug') and OPEN windows and portlights (can be covered to prevent snow rain, etc. from entering) is probably your best bet. An 'open' boat with a dry bilge and emptied tanks will quickly thermally equalize with the outside air due to the constant 'change of air' (convection). if you have thermal equilibrium due to air being able to rapidly 'change', you will have the least amount of 'condensation'. Ask yourself - why dont 'rowboats and dinghies' have problems with 'condensation'.

The goal is to keep the 'inside temperature' equal to the 'outside temperature; closing a boat up tight results in a 'time lag' for the temperatures to 'equilibrate' or become equal inside vs. outside.
