Valiente, Thanks for the input. Yes, heavy boat 33K hanging on the straps.
That's incredible. I have (as mentioned elsewhere) a steel 40 footer cutter with vast tankage that weighs 29,500 lbs. in the straps. The boat beside me in the yard is a Tayana 45, and while you wouldn't think a steel tank like mine would have anything to worry about, but I wish it wasn't upwind of me when those winter gales start blowing. It's the only boat heavy enough to crush mine like a pop can if its cradle failed.
Of course, my full keel might act like a wedge...
