It easily lifts my WS23LSV with full fuel and all the gear, ice chests and a couple of humans.
We tried a new 247 on it with 2 guys on board and it wouldn't lift it.
So we figure it will lift 4500 lbs
Its a front mount style so doesn't need to be attached to both side of the slip
I've had it since 2002 and it has performed flawlessly
I keep my boat on it on Lake Ray Roberts year round
I'm building a new garage so won't need the slip anymore
