There is alot of dfference between hibernation and simple closed storage
. Most of it relates to system protection/integrity, heat/cold management, humidity control and protecton of the exterior UV ad polution. Boats should be adequately ventilated to manage mosture or closed completely with no leaks
Bugs can also be a problem. I have hear of people using an inert dry gas inside the vessel like Argon to flood the spaces to cut out the potential for mold
growth and it drives the bugs nuts.
techniques work well to control heat and UV. UV inhibitors help protect sensitive surfaces.
Systems need to be run occassionally or pickled completely to avoid drying out packings and seals
motors do well in dry storage unless there is a mosture problem...then they need protection and routine servicing.
How much are you paying for dry storage and what kind of facility are you at?
