This may be a bit off topic, sorry PKv.
MrsMac and I started prepping when we lived on our sailboat in the PNW. At minimum, we had one item for everything that might break.
I remember motoring (no wind) up to Nanaimo, BC Canada. We were on a vacation and there is a great restaurant in Nanaimo that serves GREAT halibut fish and chips. Any way I digress.
We were motoring along with the flood tide and all of a sudden by engine started to over heat. Shut the engine down, grabbed a chart and identified a cove about a mile to our west. Started the engine and at very low RPM's limped Mad Max over to the cove. Once there, dropped anchor and told MrsMac we were swinging on the hook that night. Halibut fish & chips would just have to wait.
MrsMac shrugged her shoulders, opened up one of our food lockers and grabbed 2-cans of clams and some pasta. I opened up the wine cellar (The bilge) and grabbed a nice Chardonnay.
Once our basic needs were met, I tore off the cover to the engine compartment and started the process of looking for the over heating problem.
Was the water intake clogged? Nope. The strainer was clear. Turned the engine on and there was no water coming out the exhaust. Mmmmm.
To make a long story short, I checked the heat valve and it was stuck closed. Okay, we are getting somewhere.
I went to the locker that housed Volvo marine engine parts and voila! I had a new one stashed.
Installed it, started the engine, and sure enough water was exiting the engine through the exhaust just like it was supposed too. Let the engine run for an hour or so to make sure nothing else was not working and all was good.
Turned on the anchor light, opened the bottle of chardonnay, and turned on the ham radio to listen to the BBC from the United Kingdom. Watched MrsMac mix up linguini with white clam sauce, a salad, and garlic bread.
After my first glass of wine, and in the middle of listening to the news from the UK that seemed to be focused on, OJ being found not guilty. MrsMac, turned to me and said, "dinner is done. Please light a lamp and set the table.
That little drama, was amongst many great evenings on old Mad Max. Swinging at anchor in a cove on Vancouver Island. Why? Because I had the part and a serious drama turned into a very nice evening.
It is called being prepared.
