I sail a Cal 29. 8,000# unloaded. Here's the anchors and wind speed calcs:
Working Anchor: (to 30 kts) Bruce 10KG, (sand, mud, gravel)
Storm Anchor: (to 45 kts) Fortress FX 16 (sand, mud with flukes adjusted)
lunch hook kedge) Danforth 15# (sand, mud)
Back-up anchor: folding SS Northill (sand, gravel, rock, weed)
Tandem Anchors (theroetically to 80 kts. or surging) Fortress/Danforth I mad up a chain arrangement to do this.
Agree that Hinz is dated especially on anchor types with all the new anchors out there. It served the era of technology on my boat and was a good source for load/strenght/calculations. Id doesn't cover cleats all that well and I found out was that my cleats were the weak point in the system. When you check out shear stress for threaded ss bolts it's quite low. If you can get the cleat stress on the non-threades shank you can handle a lot more. The tables are hard to find. I put in a larger cleat with 4 larger diameter bolts and a pretty large 1/8" ss backing plate to cover the calculated stress.
