So, I managed to lift a boat with two ratchet straps of 5 ton rating. I assume that is the SWL. Not sure what the boat weighed? Trad Breton fishing type of 16ft, with a 200kg Volvo Penta donk.
Now, I have been offered a grp 20ft sailing boat, for free.. I need to lift it up so we can get a trailer under it.
So, about how much can a 5ton strap lift?
I looked at the spec for the boat and about 950kg.
Then looked at the ratchet straps and seemed to be about 9:1 ratio. If I heave at 50kg, then 450kg. So a bit short, for two straps.
Anybody with experience in this?
