While I applaud your idea of creating a website for your boat, travel, plans etc. I wonder why you would not consider using an already existing blog space like: SailBlogs | Sailing Blog Hosting & Social Network
Apparently it is free, you can post text and pics. It already has a lot of bells and whistles built into it.
You would not have to touch a line of code and could spend your time writing and taking photos instead. There is a fellow here named Chris (SV Pelican Fate, part deux | The Big Trip
) who blogged his way down to the Bahamas and back up to NY with his family.
Having said that, I have built a website for my boat using Dreamweaver and while it is not that difficult it does take a bit of time and patience and you have to pay something for the domain name and host server.

Good luck however you proceed.
