If you don't want a blog but just a personal record, you can store a document in the cloud somewhere, a Google doc, for example. You'll want something that is available wherever you have internet access, can be downloaded for offline access and will sync later. You could convert your online record to another format and print it or send it electronically to friends, family, etc. Many of the cloud docs can be shared with others so that they can view and/or collaborate.
I use multiple Google Docs, one for maintenance, another for ToDos, including parts shopping lists, and another for a log. After having the boat for 5 years, the docs were getting too long, so I started breaking the docs into seasons or in smaller parts that made sense. I use other cloud tools or documents for noting specifics about important parts, model numbers, radio callsigns, license expiration dates/renewal instructions, anchor rode marking, fuel purchases, and on and on.
It can be a bit of a mess at times, but I've evolved the organization over time so that I have what I need wherever I am. It takes time to know what you need, when you'll need it, what devices it has to be compatible with, and where it needs to be to be accessible. Accept that you're not going to find the best answer for you with the first thing you try.
I'm experimenting with an HTML-based desktop wiki which I really like and use for all of my project ideas and notes, but I haven't figured out how to store it in the cloud so that it's always accessible.
Good luck.
Greg.
