Despite the fact that the duct appears to be galvanized it will likely eventually rust in spots. You might want to paint, coat, or otherwise line the inside (if it is snap-lock just open it up and lay it flat.) Regardless, first, clean the surface, it may contain light oil used during forming.
Also, do not store items in the tube, especially damp or wet sails, just use it to transport them to the water and home. Due to possible moisture in the contents (wet or damp sails, sheets, PFD, etc.) or just atmospheric humidity and temperature changes, you can expect the insides to "sweat" as moisture condenses- that can quickly lead to rust and mold.
It is summer- you should be sailing and not messing with the trailer!!!
