Depends on which context in which you’re interested. Internet? Hm… For the refit part and thinking through/designing for all of these factors, maybe The Duracell Project (https://www.youtube.com/@TheDuracellProject/videos). Most of the people I know actually doing this stuff are… actually doing it. There’s not a lot of time and bandwidth to create an accessible internet resource. And the seriously salty folk, most of them barely have email. Among my sailing peers, I’m the most technologically capable, and that’s not saying much. :D We tend to eschew the high tech that invariably will let us down when we most need it. Much of seafaring knowledge and skills are born from hard experience and sitting around getting drunk with old salts, which is its own kind of hard experience. :D

You start small, push the limits, break shit, find fixes in order get back to port, and find what works for you with what you have at hand. Anything you couldn’t fix, you go to your marina neighbors or the internet to find jury-rigs for that specific failure mode. In your day-to-day life, learning some basic knots, how to make whoopie slings and soft shackles with Dyneema, wilderness first aid, wilderness first responder training, even basic disaster preparedness all help change your perspective on how you approach your day. For example, drilling for natural disaster response, at least for me, shifts my mindset into a “what could go wrong,” “what are the failure modes of [this critical component]” way of thinking. These are aspects you can explore without a boat or having wilderness nearby.

I haven’t watched a lot of her stuff, but Wind Hippie Sailing (https://www.youtube.com/@WindHippieSailing/videos) is a seriously badass solo dirtbagger (not a pejorative; it’s technical term cribbed from rock climbing). Solo sailors are a breed apart and a few steps above the rest of us salty dogs who have crew.

Downloaded to my Kiwix app or installed on phone/tablet and mirrored across a bunch of backup devices:

• 100 Rabbits
• Ready.gov
• Animated Knots
• U.S. Army Ranger Handbook (hard to ignore 200 years of military refinement)
• Survival Manual (sadly no longer available)

Now if you’re okay with books, lots of great resources there.

• “Sailing Alone Around the World” by Joshua Slocum
• “Sailing a Serious Ocean” by John Kretschmer
• “Cruising in Serrafyn,” “The Self Sufficient Sailor,” “The Capable Cruiser” by Larry and Lyn Pardey; hell, almost all of their books are great reads; they sailed the world for decades with almost no electric and no engine
• "Where There Is No Doctor and “Where There Is No Dentist,” Hesperian Health Guides
• “Annapolis Book of Seamanship” by John Rousmaniere
• Just about anything by Fatty Goodlander, funny stories on the dirtbagging lifestyle

Let me know if you any additional questions. Happy to share.

Edit to add: Practical Sailor (https://www.practical-sailor.com/), a great internet resource . JFC, how did I forget that?!
