I just tend to live in the mystery…
Seriously though, I tried various organizing tools in the past, both analog and digital. None really stuck for me. What did stick is just living with the space. Things tend to find their natural location, so I learn where to go for them.
As far as inventory of spares, I’m mildly unorganized. I have separate storage bags for various systems (electrical, plumbing, engine, fibreglass, varnish, general tools, power tools). I keep small spares with the various systems, and I keep larger spares in a few bins. I guess I have a mental tally of most things, but I sometimes get caught in my own ignorance.
For major provisioning we do use a list, but we don’t keep an accurate running tally of usage. Again, with constant usage comes awareness of what remains in the larder, so minor provisioning is pretty natural.
I guess my system (or lack thereof) works if you’re in the space all the time. Mine is my home (during the warmer months). Probably not so good for those who only use their boats periodically.
SanderO, I am once again in awe of you. I only wish my mind was that organized — seriously!
