"No sense of perspective." Perhaps I didn't provide enough information.
I'm not talking about going out with NO anchor. I have three anchors, two of which are well-suited to the lake according to those who replied. (thanks!)
I'm not the type to pay a premium for the Latest Thing because it's a little better than what I have. I buy the not-newest cell phone when mine wears out, and until the used car market went nuts, I drove used cars and always paid cash. Even now, I'm driving a 6 year old Subaru (bought new, cash) and I see the new ones with better safety features and heated steering wheels but a price tag that's half my household income and I'm glad I have what I have and don't have to swing that payment.
If I lose an anchor and have to buy a new one - it will be one of these box anchors. But until then my Danforths that have worked for years (on sailboats that can't run from storms - on much bigger water than an inland lake) will have to do.
When I first started sailing I read a lot of books - Chichester, Roth, Slocum, etc. Guys that were circumnavigating. They heavily influenced my decisions. I still carry way more safety and "what if" gear than necessary. What little storage I have is a weird combination of chandlery and a prepper's bunker.
I don't recall what my insurance deductible is, but my annual policy is ten bucks more than that anchor.
This boat is no peach. Sturdy, and in exemplary mechanical condition, but it's not going to win any awards.
