Probably would be sensible but corrosion would be the major drawback as none of these things are specifically designed for marine use. On Raven we have a permanently open hatch that vents under the dodger thus eliminating any concerns about oxygen depletion.
ps - what beautiful lines your hull has. Reminds me a lot of a smaller version of the Alden ketch "Minots Light". I wonder where she is these days.
