Over the past decade or more, "regular" topics come up repeatedly.  In developing responses to questions, many of us use the handy links to earlier discussions.  I've developed these "101" topics, which are groups of links to popular subjects and those discussions.  I'll leave this topic as a sticky, and add any new "101"s that may develop.  Many of them include links to other websites and message boards, since boat systems are not always boat-specific.

Our "very own" ARCHIVED FAQs and Projects pages - no longer updated, most have been posted to the tech wiki, but these are the very first efforts on our website, predating this Forum and its contents:


Also, don't forget to use the C34 tech wiki.  Just click on the link at the top of every page.

Steve's Anchoring 101

The Rocna.  All 20kg of it with 100ft of chain.  The rest of the world can debate all they like.   When I pull into a place like Bodega Bay at midnight and the fog is so thick I can't see the jetty 50 feet away to make an entrance, I drop my hook in the rolling ocean swells with the surf crashing (Foster says it's like staying in a cheap Best Western beside the highway), and I sleep.  And in the morning I have a windlass to pull the beast up and I wouldn't trade it for anything.   (I also wouldn't add more chain - this works perfectly in 25 to 30 feet of water - you let all the chain out and you tie off nylon at the preferred scope and don't bother with separate snubbers and chain hooks and all that stuff...

This was our best upgrade.

LifePO4 Batteries

Hi All,

As many of you know I suffered a major stroke back in September which Has left me paralyzed on the left side of my body. It has also left me with some vision issues. The good news is I'm back to writing articles for Marine how To.com Using Dragon speech to text... . I just published an article that I started the outline of back in August, before the stroke.The article is sort of a 101 level course on lithium iron phosphate batteries for boats.I know there has been a lot of interest in the forum recently about lithium iron phosphate batteries, so this may help.
