which converts to roughly a min of 2x3x4x30=720 sq ft. and a maximum of around 2x3x5x30=900 sq ft.
not to mentioan that i could have roughly an added lets say 120 sq ft from hanginf plants above
...
lets say that this section of the boat is air tight with only one vent that has a system for controlling moisture, humidity, and salinity
lets leave out the lighting system for now as i my idea is a preliminary one
there will be no glass(at most a plastic alloy or other type) but for the sake of arguement lets just say that i have no glass and no electric lighting system

A picture is worth a 1000 words. How about attaching a rough sketch of the greenhouse as you have imagined it? It would help us visualize your idea.

You did not comment on the input you got earlier.
This is a discussion board where you can get some really professional advice about boat design. Not greenhouses! If you however have that knowledge to put in here, you will perhaps get somewhere here.

Since you also don’t seem to have a clue about how to grow crops there really no point in this.

I repeat my advice - This is a cool idea but you have approached it from the wrong side.

A rough sketch is not art ...... just scribble

And rest of us are terrible gardeners, so your project probably ends here.

They are all willing..............

You would have to cope with some upfront cost though!

Most probably you would do much better with a project manager to start with.

Why don't you just grow mangrove trees on the deck? You just need a big tank of salt-water and a source of nutrients. They have edible "fruit" (actually air-root nodules, I think), leaves for tea, and you can use the wood as fuel (or even make another boat with it - it's good in salt water apparently).
