With a carport having Colorbond sheet roof I had avoided a pulley lift because of the need to instal extra cross beams, however yarning to a builder mate he advised that riveted pulleys and no additional support would be adequate to lift the kayaks.
Got a couple of saddles, pulleys and cleats to tie off the rope at Whitworths on Sat arvo and riveted in position with one pulley each end, and while it worked it was a deal of effort to lift the yak.
Sunday morning I made a couple of extra saddles from aluminium [Whitworths closed] and with the inclusion of a second pulley in the sling [Bunnings cheapy] the lift became a breeze, although webbing slings around the boat had a lot of stretch and the one on the bow kept going towards the narrow end as weight came on to the lift and had to be tied back to stop the slipping.
Into bed to think, and come up with a solution overnight.
The stern end was easy, a board with a couple of bolts through scuppers, and a piece of ply underneath and nuts finger tight to remove the slack; on top of the board some angle aluminium to shackle to the pulley and no longer use a bolt in the shackle [as in the pic]] instead use just a bent 3" nail which is a lot quicker to insert.
For the front pulley, made a triangle loop from the wire handle of a bucket and inserted a ratchet strap to hold firm to boat and eliminate stretching, with the pulley connected to the loop by a nut and bolt and have used a fibre tap washer on th wire side to stop the bolt pulling though. To stop the ratchet from sliding to the bow I screwed 2 saddles on the yaks deck to prevent slippage [and can be used on the water for tying off]
After the kayak is raised I include an extra black webbing sling with a hook at either end as an added precaution.
The unsupported colorbond depresses about 2mm at most under load, and the four 4mm rivets on saddles are doing the job in safety.
Anyone contemplating something similar just get the gal pulleys [$5 ea] they are doing the job as well as the quality pulleys [$13 ea]
All the fittings and 12m of 6mm silver rope added to about $60
