I am once again trying to reduce my volume of stuff. I currently live on a 30 foot racing sailboat and have a 5 x 5 storage unit. I hate living in clutter and would like to end the need to pay rent on the storage space.

I am trying to be guided by the principle that if I have not used it lately [1 year? 2 years?], then I must not need it and should find it a new home. This is remarkably painful.

I am also trying to follow the principle of replacing bulky stuff with functionally equivalent compact, lighter stuff. Candidate new gear is proving remarkably expensive.

And, I am trying to follow the principle that each set of functional gear should be stored as a "kit" within one bag or container. This has meant spending a lot of time thinking of, creating, or shopping for containers.

As a further matter of storage principle, I am labeling most sides of most containers.

Are there principles of storage that I am missing or about which I am in error?

Thoughts?

Thanks.
