Hi Jen
I haven’t tried it but I have read that the best way it to tie webbing or rope around the front and rear float arms where they join the hull and then join them to form a loop which you then hoist from (I recommend using a Butterfly Knot to make loops in the middle of a rope).
Ensure that the lifting point is slightly towards the stern from the centre of gravity so that the bow is slightly down which keeps the mast and shrouds away from your crane – although you may want to add another line from the crane to the bow as this can tip forward if there’s any water in the hull or floats.
Hope this helps
